Common questions

Can a unburned oil damage the oxygen sensor?

Can a unburned oil damage the oxygen sensor?

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.).

Can a bad mass air flow sensor trigger a check engine light?

Bad mass air flow sensor with no check engine light? Sometimes a mass airflow sensor can start to fail and even trigger engine error codes such as P0101 and P0102, without triggering a check engine light. There must be a problem with the mass airflow sensor circuit for the check engine light to illuminate.

When is a bad throttle position sensor a warning sign?

Engine won’t idle smoothly, idles too slowly, or stalls If you start to experience engine misfires, stalling, or rough idling when the car is stopped, it can also be a warning sign of a failing TPS. You don’t want to wait to get this checked out!

How to avoid the need to replace the O2 sensor?

The price of the component varies according to the brand and engine type. The least expensive option, with no need for disassembly and entailing the shortest service time, and which is an alternative to part replacement, is hydrogen treatment via the Carbon Cleaning station.

Where is the O2 oxygen sensor in the engine?

Also, The (O2) Oxygen Sensor is not able to measure the air or the fuel entering the engine. Because, the (O2) Oxygen Sensor is located in the exhaust and that where it reads the actual oxygen content in the exhaust. Depending on the year; make and model of your vehicle you could have anywhere from one to four (O2) Oxygen Sensors.

What happens if the O2 sensor fails to function?

Finally, if your (O2) sensor fails to function properly; your engine management computer cannot determine the air to fuel ratio. Therefore, the engine is forced to guess how much fuel to use. Resulting, in a polluted engine and a poorly functioning vehicle. It’s true that many of these symptoms could be caused by various problems.

What’s the difference between AFR and O2 sensors?

What distinguishes Air Fuel Ratio Sensors from regular O2 sensors is that the AFR Sensor is what is known as a wide range O2 sensor whereas the basic O2 sensor is a narrow range sensor. It can detect a wider range of air/fuel ratios than the basic O2 sensor.
