Code P1135
I have just bought a RX300 1999.
I checked the check engine light error at AutoZone and the error code is P1135 (Air/Fuel ratio sensor heater circuit malfunction) (bank 1 sensor 1)
I have read many topic but I confuse on the reason of the Oxygen Sensor or Mass Air Flow Sensor?
Could you help me and give me the thread help me to solve it?
Is this the right thread?
