Customer Question
Replaced the 02 sensor...

Replaced the 02 sensor and cleared the POO31 code. the light came back on 30 minutes later in stop and go traffic. 2003 Camry with 80k miles

Mechanic's Assistant: Sometimes things that you think will be really complicated end up being easy to fix with a Toyota. The Toyota Mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so he can help you best.

Ive replaced the sensor twice in 2 days, hoping its not the ECM

Mechanic's Assistant: Are you hoping to fix this yourself?

Is there a drive cycle or distance I need to drive at 60 mph to keep the code clear.

Mechanic's Assistant: Is there anything else the Toyota Mechanic should be aware of about your Toyota?

Stock 4cyl, no other issues
