P0135 Generic 02 sensor heater circuit malfunction(bank 1 sensor 1)
Honda - Code P0135 Generic 02 sensor heater circuit malfunction(bank 1 sensor 1) Question: I have a 2002 Honda Civic 1.7L. Recently my engine light came on and I put the auto scanner to it and it says "P0135 Generic 02 sensor heater circuit malfunction(bank 1 sensor 1)". I priced the Honda dealer sensors($110 ea.) and Autozones sensors($55 ea.), so I went with autozone, and then took them to a mechanic to have them installed. Once they were installed the mechanic said that he keeps clearing the computer but the engine light keeps coming back on for the bank one sensor one, or upstream sensor. He also said that sometimes with sensors you might have to buy the Honda original sensor from the dealer instead of the aftermarket sensors, is this true? What do you think it could be? On my auto scanner in the I/M status it states MIL status on, Misfire monitor- ok, Fuel sys. monitor- ok, Comprehensive comp. mon.- ok, catalyst mon. Inc., Evap. system mon.- inc., oxygen sensor mon.- inc., oxygen sensor heater- ok, Exhaust Gas Recirculation sys. mon.- inc. I don't know if the I/M status will help you out or not. Already Tried: I replaced both oxygen sensors already with bosch autozone sensors Answer: I have seen this many times the aftermarket sensors will not work in most Honda's you need to get factory parts to fix your problem.
