P1167 2004 NISSAN ALTIMA SEDAN Possible Causes
- Faulty heated rear oxygen sensor, bank 2
- Bank 2 heated rear oxygen sensor harness is open or shorted
- Poor electrical connection in the heated rear oxygen sensor circuit, bank 2
- Fuel pressure
- Injectors
- Intake air leaks
How to Fix Code P1167 2004 NISSAN ALTIMA SEDAN?
Start by checking the “possible causes” listed above. Visually inspect the corresponding wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector pins.
Technical Notes
Replacing the rear oxygen (O2) sensor usually resolves the issue
When is the Code Detected?
The P1167 code is triggered when the maximum sensor voltage is not reached at the specified voltage.
Possible Symptoms
- Engine light on (or service engine soon warning light)
- Possible high fuel consumption
- Possible excessive smoke from exhaust
P1167 2004 NISSAN ALTIMA SEDAN Meaning
The heated oxygen sensor 2 (rear), after three-way catalyst, monitors the oxygen level in the exhaust gases on each bank. Even if the switching characteristics of heated oxygen sensor 1 (front) are shifted, the air-fuel ratio is controlled to stoichiometric by the signal from heated oxygen sensor 2. This sensor is made of zirconia ceramic. Zirconia generates a voltage from about 1 V in richer conditions to 0 V in leaner conditions. Under normal conditions, heated oxygen sensor 2 is not used for engine control operation.
