If the P0136 code is triggered, it means that the ECU has detected a problem with the O2 sensor circuit. This could be due to a faulty O2 sensor, a damaged wiring harness, or a problem with the ECU itself.
Symptoms of the P0136 code can include:
* Check Engine Light illuminated
* Decreased fuel efficiency
* Engine hesitation or stalling
* Rough idle
* Increased emissions
If you experience any of these symptoms, it is important to have your Toyota RAV4 diagnosed and repaired as soon as possible. The P0136 code can lead to serious engine problems if it is not addressed.
Here are some possible causes of the P0136 code:
* Faulty oxygen sensor
* Damaged wiring harness
* Loose or disconnected electrical connections
* Problem with the ECU
To diagnose the P0136 code, a mechanic will use a diagnostic scanner to retrieve the trouble code from the ECU. The mechanic will then perform a visual inspection of the O2 sensor and the wiring harness to look for any damage. The mechanic may also test the O2 sensor to see if it is functioning properly.
If the O2 sensor is faulty, it will need to be replaced. If the wiring harness is damaged, it will need to be repaired or replaced. If the ECU is the problem, it will need to be reprogrammed or replaced.
Once the problem has been diagnosed, the mechanic will clear the trouble code from the ECU and test drive the vehicle to make sure that the repair was successful.
