Research on Oxygen Sensor for Mitsubishi Montero

A vehicle's oxygen sensor is programmed to measure the levels of oxygen in the exhaust gasses that exit the car's engine. The Powertrain Control Module (PCM) uses the information in order to determine the correct air to fuel ratio for the car's engine in real time. Located in the exhaust system, the oxygen sensor allows the engine timing and fuel injection to work efficiently. A malfunctioning oxygen sensor will affect the engine performance and environmental emissions negatively, which is why it is important to make sure that you get a Mitsubishi Montero Sport o2 sensor replacement as soon as you detect problems.

4 Signs that You Have a Bad Oxygen Sensor

Like other parts in your vehicle, the oxygen sensor will need to be replaced eventually. If you have a faulty oxygen sensor, there will likely be signs that indicate problems. Here are 4 signs that indicate that you need to get your o2 sensor replaced:

First, the fuel mileage decreases suddenly. If your o2 sensor is defective, your air-fuel mixture is likely to be too rich and have a direct effect on your car's fuel efficiency. Second, your Check Engine Light will flash, or the indicator lamp on the dashboard will malfunction. Although these problems can occur for other reasons, the chances are that your oxygen sensor is failing or defective. Third, the overall performance of your vehicle will be poor - stalling, rough idling, hesitation on acceleration, etc. and finally, there will be a failure to pass smog tests. The Environmental Protection Agency (EPA) reports that about 50 to 60% of all emission test/smog test-related failures are due to defective oxygen sensors, which cause high or low CO emissions.

When to Replace the Oxygen Sensor

If your car was manufactured within the last 15 years, you should get the oxygen sensor replaced every 60,000 to 90,000 miles. This important component of your vehicle will wear out over time completely failing ultimately. As soon as you notice any of the signs mentioned above, you should drive your car to the nearest auto garage for an inspection. If necessary, they will recommend that you replace the oxygen sensor.

Keep in mind that it is important to get a certified professional to handle your vehicle's repair and replacement needs. You want to make sure that only the best-trained pro takes care of your car's needs for the best results.

Cost of Oxygen Sensor Replacement for Mitsubishi Montero

To replace your Mitsubishi Montero oxygen sensor, you will need to spend an average between $235 and $442. Labor will cost you between $70 and $89 while for parts, you will need to spend between $165 and $353. Taxes and fees are not included in this estimate.
