My Toyota camry has had the check engine light on for some time. I finally took it and had the codes pulled and was told it was code p0136 and that I needed a new Oxygen Senser. Which one do I need to replace?
Code P0136 - o2 Sensor circuit malfunction B1 S1.
This means the downstream o2 sensor has an issue and is not sending a signal to the computer. The Downstream o2 sensor is located after the catalytic converter assembly in the exhaust pipe.
The Fix: Replace the failed o2 Sensor
