Possible causes
– Faulty Air Fuel Ratio Sensor 1 Bank 1
– Air Fuel Ratio Sensor 1 harness is open or shorted
– Air Fuel Ratio Sensor 1 circuit poor electrical connection
– Air Fuel Ratio Sensor 1 harness is open or shorted
– Air Fuel Ratio Sensor 1 circuit poor electrical connection
When is the code detected?
The current amperage in the heated air fuel ratio (A/F) sensor 1 heater circuit is out of the normal range. An excessively high voltage signal is sent to Engine Control Module (ECM) through the heated air fuel ratio (A/F) sensor 1 heater.
Symptoms
– Engine Light ON (or Service Engine Soon Warning Light)
P1032 NISSAN Description
The Engine Control Module (ECM) performs ON/OFF duty control of the Air Fuel Ratio (A/F) sensor 1 heater corresponding to the engine operating condition to keep the temperature of A/F sensor 1 element at the specified range.
