The problem turned out to be a malfunctioning oxygen sensor. A faulty oxygen sensor can cause up to a 40 percent drop in fuel economy. Nearly one in 10 "Check Engine" lights is caused by a malfunctioning oxygen sensor. At the first sight of a Check Engine light, most owners of under-warranty new cars will simply head for the dealership.

But owners of older cars, or those on a budget, might want to go the do-it-yourself diagnosis route to save money. The CarMD diagnostic device will read the code and also connect to your desktop computer with more background and local repair and cost information.

How to Replace an Oxygen Sensor in Your Car (Air Fuel Ratio Sensor)

If your car's "Check Engine" light is glaring at you, it's probably because the oxygen sensor is malfunctioning. That's right, the oxygen sensor. It's a little device that's a mystery for most drivers but its misbehavior is the problem that most commonly triggers a Check Engine light, according to CarMD.

The oxygen sensor unseats the formerly most common Check Engine light culprit: a loose gas cap.

There are fewer reports of that problem because savvy motorists have learned to fix it themselves and consumers now buy new cars with capless gas tanks. But don't despair. Replacing your car oxygen sensor will keep you from wasting money by burning extra gas, and the repair isn't horribly expensive. We know this firsthand. We had to replace the O2 sensor on our Lexus ESthe subject of our Debt-Free Car projectand it wasn't as much of a hassle or expense as we had feared.

After the dreaded Check Engine light appeared in our Lexus, we plugged the CarMD device into the car's computer to read the error code. In our case, the code was P, which meant that the oxygen sensor in "bank 1" was malfunctioning. It was surprising to learn that something was wrong with the car, since it still seemed to be running fine. Even though a car seems to be behaving normally, a faulty oxygen sensor will cause the engine to start "gulping down gas," says Kristin Brocoff, director of corporate communications for CarMD.

She says this problem can cause up to a 40 percent reduction in fuel economy. Sure enough, when we checked our fuel record for the driving we did while the Check Engine light was on, our mpg had taken a hit.

The oxygen sensor, developed in the early s, is an essential part of the car's emissions control system, says John Nielsen, director of engineering and repair for the American Automobile Association AAA. The sensor is about the size and shape of a spark plug and protrudes into the car engine's exhaust stream. It determines if there is a lot or a little oxygen in the exhaust, so the engine can make adjustments to the amount of fuel being used in the engine to run at maximum efficiency.

Oxygen sensors in older cars fail for a variety of reasons, according to Boscha leading manufacturer of auto components. In some cases, sensors are fouled by gasoline additives or oil from worn engines. Newer oxygen sensors can lastmiles if conditions are right, but often problems occur sooner.

After we plugged CarMD's diagnostic device into the Lexus' onboard computer port, we connected it to our desktop computer. It accessed a database of information about this engine code and how to have it repaired. At the first sight of a Check Engine light, most owners of new cars that are still under the factory warranty would simply make a beeline for the dealership's service bay. But car owners on a budget might want to go the do-it-yourself diagnosis route to save money.

By using the CarMD device, or any engine code reader, drivers can learn what the problem is, and the skill level required to fix it, before attempting the task.Cleaning O2 sensor How to avoid the need to replace the Oxygen sensor. Its role is to inform the ECU of the oxygen content of the burned gases that result from combustion. The o2 sensor helps to ensure that the amount of fuel injected into the cylinders for the air-fuel ratio is at an ideal level.

The o2 sensor ensures low fuel consumption as well as reduced pollutants emitted from the engine. It is therefore an important component to help pass vehicle inspection.

The latest standards of emissions require the presence of a second lambda probe, located after the catalytic converter in order to determine its effectiveness. A faulty oxygen sensor has the direct consequence of disrupting the engine air-fuel balance.

This leads to an increase in pollutants emitted by the engine, as well as causing the engine to stutter and consequently fuel consumption to increase. The lifespan of a Oxygen Sensor iskm on average, as long as it is not shortened by engine malfunction.

Unburned oil due to engine misfire may contaminate the probe irreversibly. Exhaust leaks also damage the Oxygen Sensor, leading to an intake of air which can cause a dangerous increase in temperature.

To ensure the maximum lifespan of the Oxygen Sensor, it is necessary to perform strict engine maintenance spark plugs, air filter, et al. It is therefore necessary to have this service administered at a professional garage. How to clean the O2 Sensor There are two ways to clean or replace the oxygen sensor, falling within a broad price range.

This device is part of a car's emissions control system: it's roughly the size of a spark plug, and tests the oxygen levels in a car's exhaust stream.

Before you can clean an oxygen sensor, you have to remove it from the exhaust manifold. To make this easier, spray the sensor with WD40 and let it sit for 15 minutes. Once the sensor is loose, unscrew it and let it soak in a container of gasoline for at least 8 hours. When you do this, prevent leaks and fires by making sure the container is gasoline resistant and by covering it with a lid. Keep reading to learn how to find the oxygen sensors.

Article Summary.Oxygen sensors are small devices on your car or truck that measure and balance the oxygen to fuel ratio. Part of the emissions control system, the sensor feeds information to your car's power control module, which is your car's computer brain.

Typically these sensors are mounted near along your exhaust pipe on each side of your catalytic converter. Over time they can become clogged and stop working. When this happens it can cause your car to kill unexpectedly. You can clean your oxygen sensor to get a few more extra miles out of it, but ultimately they will have to be replaced when they begin to act up. Determine which sensor is bad. You can bring your car to any auto parts store and have them run a free diagnostic test which will tell you the sensor that is going bad and its location.

How to Repair & Clean Oxygen Sensors

Locate and remove the oxygen sensor. The sensors on your car are typically on the passenger side and are mounted directly onto the exhaust pipe on either side of the catalytic converter. Remove the sensor by unbolting the retaining bolts with a socket set and then unplugging it from its electric wiring harness. Gently scrub the metal tube-shaped end of the sensor with a wire brush to remove excess dirt and grime. Use a can of compressed air to spray it and clean it further.

Pour some gasoline in a plastic container. Set the metal tube-shaped half of the sensor in the container with the gas. Let it sit in the gasoline over night. Reinstall the sensor onto your vehicle by first setting it in place and putting the retaining bolts back in place and tightening them with the socket set. Plug the electric wiring harness back into the rear of the sensor. This should allow you to get extra miles out of the sensor before having to completely replace it.

On the batting front, Nitish Rana proved to be the surprise performer for the side, scoring a half-century while Hardik Pandya showed that he could a reliable finisher in the future, guiding his side to a win in the last over of the game. Extra Cover: IPL 2017 MI vs SRH: Sunrisers Hyderabad (SRH) Probable playing XI against Mumbai Indians (MI)In the bowling, Krunal Pandya proved to be the hero, picking up three wickets to stem the flow of runs of the Knight Riders.

With the presence of some explosive players in their ranks, the Mumbai Indians could make use of the shorter boundaries at the Wankhede and post a big total on the board.

Critically for them, Rohit Sharma will need to open the innings and give himself 20 overs to bat which would give him the chance to stand up and put a tall score on the board.

With the likes of Warner, Henriques and Yuvraj in the top four, the Sunrisers will look to make good use of the conditions on offer at the Wankhede. The venue also presents an opportunity to Dhawan to get some runs under his belt. Predicted winner: With the form that they are currently in, the Sunrisers Hyderabad look like the favourites to come out trumps in this game.

The Standard Deviation shows the relation that set of scores has to the mean of the sample. Again lets take the set of scores:to compute the standard deviation, we first find the distance between each value and the mean. We know from above that the mean is 20. So, the differences from the mean are:15 - 20. Next, we square each discrepancy:-5. Here, the sum is 350. Next, we divide this sum by the number of scores minus 1. Here, the result is 350. This value is known as the variance.

To get the standard deviation, we take the square root of the variance (remember that we squared the deviations earlier). This would be SQRT(50. Although this computation may seem convoluted, it's actually quite simple. To see this, consider the formula for the standard deviation:In the top part of the ratio, the numerator, we see that each score has the the mean subtracted from it, the difference is squared, and the squares are summed.

In the bottom part, we take the number of scores minus 1. The ratio is the variance and the square root is the standard deviation. In English, we can describe the standard deviation as:the square root of the sum of the squared deviations from the mean divided by the number of scores minus oneAlthough we can calculate these univariate statistics by hand, it gets quite tedious when you have more than a few values and variables.

Every statistics program is capable of calculating them easily for you. For instance, I put the eight scores into SPSS and got the following table as a result:The standard deviation allows us to reach some conclusions about specific scores in our distribution. Assuming that the distribution of scores is normal or bell-shaped (or close to it. This kind of information is a critical stepping stone to enabling us to compare the performance of an individual on one variable with their performance on another, even when the variables are measured on entirely different scales.

Nearly all the arrangements went without a hitch and what didn't go smoothly wasn't due to Nordic Visitor getting it wrong and indeed didn't ruin the trip at all (eg the guesthouse in Reykjavik wasn't aware of my travelling companion's very early arrival and were not prepared).

My only negative comment is some of the worthwhile sights might not be on their recommended itinerary so do a little research of your own. Also a bit more time (a day perhaps) in the north east of the country would have been ideal.

I dropped by their office in Reykjavik at the end of the tour (a little tricky to find as it is tucked away on the edge of town) and was pleasantly surprised by a request to do a brief video of our tour highlights for other travellers. I received a beautiful hardcover book of Icelandic photographs for my trouble. Iceland is a Josie, Puerto Rico Iceland Grand Tour, July 2015 16 amazing days in Iceland Not only did Nordic Visitor delivered on everything that was needed, all the extra tours that were booked by them exceeded our expectations.

Spent 16 days on a self-drive tour of Iceland including west fjords. Every detail was taken care of, the car was excellent, the accommodations that were booked were more than what was needed.

They gave us a telephone and had regular contact with us. Assisted us every time we needed any assistance. Will recommend this company and will be more than happy to use again in the future.

Tip to travelers: Do everything with lots of time. We planned this trip more than 7 months in advance. Find about weather condition, climate and clothing needs. Overall, we had a wonderful time and saw a lot of beautiful scenery. Overall we got exactly what we came to see. The itinerary was exactly as described, all buses,trains and hotels were scheduled perfectly. The phone was a great touch and very much appreciated.

The tour was amazing and let me see Norway in a way that I had not imagined. The hotel personnel were very helpful, and the breakfasts were amazing. I thoroughly enjoyed the fjord tour from Flam to Gudvangen. It was a great tour. From booking to the final date of the tour, everything was great.
