Toyota Tercel Oxygen Sensor

The Usual Problems of a Busted Toyota Tercel Oxygen Sensor:

As an important part of the car's emissions control system, your Toyota Tercel oxygen sensor is designed to measure the fuel-to-air ratio and to send the data to the engine management computer. Through constant use, the oxygen sensor may eventually wear down; and since the oxygen sensor is located in the exhaust pipe, the toxic chemicals may also contribute to the sensor's early malfunction. When you notice signs like bad engine timing and increased fuel consumption, you have to do some troubleshooting immediately. Read on to know some of the problems you might encounter.

Poor engine timing

When your Toyota Tercel oxygen sensor starts to malfunction, it has a tendency to incorrectly determine the fuel-to-air ratio, and it will cause the engine to run irregularly. Aside from this, the faulty sensor will also have an effect on the normal fuel delivery within the engine, therefore causing the engine to miss continuously.

Pinging noise inside the engine

When you hear your car's engine pinging, this can be an effect of a faulty oxygen sensor. The pinging noise is similar to the sound of a shaking can of stones when you step on the gas pedal. What actually happens is the engine ignition timing abruptly slows down or advances because the combustion gases are ignited at the wrong time.

Increase in the emission of toxic gases

Since the oxygen sensor is the one responsible for the correct fuel-to-air ratio, it can also be the culprit when the emission of your vehicle increases. This can occur because the sensor could have inaccurately measured too much fuel in the ratio. As a result, unburned fuel will clog the exhaust system and will later become toxic gases. This problem is critical to your engine's performance and is very crucial if your car needs to undergo an emission test.

Overheating catalytic converter

If your catalytic converter overheats, you may blame the faulty oxygen sensor. This scenario is similar to the other problems because of the faulty oxygen sensor's misreading that sent too much fuel to the engine. The excess fuel becomes soot that may clog the catalytic converter and cause it to malfunction. When the converter is filled up with the excess fuel, it will turn red and soon overheat.

  • Toyota Tercel Oxygen Sensor: Prolong This Part with These Helpful Tips 27 February 2013

    The oxygen sensor of your Toyota Tercel is crucial for good vehicle performance because it measures the fuel-to-engine ratio for the engine. On a classic car like the Tercel, the oxygen sensor can be replaced every 100,000 miles. Although this is the ideal mileage, it may still vary depending on your driving habits and regular maintenance. To make sure that your car's sensor reached the ideal mileage, you should check-out these simple tips that can be easily done at home:


    Clean your car's oxygen sensor.


    One way of maintaining your car's oxygen sensor effectively is by cleaning it, and what you need is a container filled with gasoline. The amount of gasoline should be enough to submerge the oxygen sensor inside the container. When the sensor is already submerged, all you need to do is to rotate the container gently to make the gasoline swirl inside. This will allow the sensor to be washed thoroughly. When that's done, you should cover the container store it overnight. Make sure that you dry the oxygen sensor with a paper when you reinstall it to your car.


    Know when to replace your car's oxygen sensor.


    Since the first generation of Toyota Tercels has been produced in 1978, the oxygen sensors of these cars belong to the first generation of heated sensors. This means that the mileage replacement recommended for the oxygen sensors of these cars should be every 60,000 miles. On the other hand, the second generation of heated sensors for Toyota Tercels that were produced in the mid 90s has a mileage replacement recommendation of every 100,000 miles. You can use this as a guide when you need to replace the one in your car. However, the condition of the oxygen sensor can also rely on your driving and maintenance habits, so you should be aware of that as well.


    Check the performance of your oxygen sensor periodically.


    A good way to check the performance of your car's oxygen sensor is by measuring its voltage. This is also a good preventive maintenance tip that can help you detect problems in the long run. All you need to use is a voltmeter and a diagram to know the right location of the oxygen sensor inside your car.
