I have codes P0135 and P0155 displayed on code reader. Both are 02 heater circuit malfunctions. P0135 is Bank 1 Sensor 1 and P0155 is Bank 2 sensor 1. What is your recommendation on what to do? I am thinking I will need to change two 02 sensors? If so can you help me pinpoint and locate them? I believe there are four total. I need to understand which sensors I need to replace if that is the fix.
have the same problem?
