Check ingine light and your gas mileage get worse.
You can test the 2002 Chrysler 300 M knock sensor with a diagnostic tester. The diagnostic tester will tell you if the knock sensor is working.
On some cars there is a reset button in the fuse panel, check with your cars manual to see if they tell you how or where to look. There is no reset on a 300m. If the oil light is on, you are low on oil, have a bad sensor, or a engine malfunction.
You bring it to a service station and tell them to replace the oxygen sensor.
The rear oxygen sensor looks at the percentage of oxygen in the exhaust after it has passed through the catalytic convertor. The computer compares this with the reading from the front sensor to tell if the catalytic converter is working correctly.
Hi , hope you can help me. Can you tell me where the oxygen sensor and the EGR valve are located on my 1997 Buick LaSabre. Thanks
An auto xray scanner can determine if a O2 sensor is bad.
There will be a two wire sensor sticking out of the top of the "pumpkin" if it has ABS.
it sense oxygen come out from your engine to tell the PCM your car is running rich or Lean
Your MIL ( malfunction indicator light ) will be lit and a code for your O2 sensor will be logged.
Generally, the onboard diagnostics will tell you when you scan the computer codes.
Code P0135 means upstream oxygen sensor heater circuit problem right cylinder bank. Did you clear code after replacing the oxygen sensor?
The computer will tell you. If you have a "check engine" light, connect a code scanner to see what the computer has detected. If there is a problem with the oxygen sensor the code scanner will display the appropriate problem code.
