This Maxima failed the MIL/check engine light due to a warning lamp failure. The fault codes reads:
P0325 Knock Sensor 1 Circuit Malfunction (Bank 1 or Single Sensor) and P0141 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor2)
With four sensors, one on each side of the motor and two before and after the catalytic converter, the mystery is finding which is setting the fault code. Any suggestions on which one of the four O2 sensors blew the heater circuit?
Thanks
