P1167 NISSAN - Heated Rear Oxygen Sensor 2 Maximum Voltage Monitoring Bank 2
P1167 NISSAN Possible Causes
- Faulty Heated Rear Oxygen Sensor Bank 2
- Heated Rear Oxygen Sensor Bank 2 harness is open or shorted
- Heated Rear Oxygen Sensor Bank 2 circuit poor electrical connection
- Fuel pressure
- Intake air leaks
How do I fix code P1167 NISSANCheck the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
Cost of diagnosing the P1167 NISSAN code
Labor: 1.0The cost of diagnosing the P1167 NISSAN code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
When is the code detected?The P1167 code is triggered when the maximum voltage from the sensor is not reached to the specified voltage.
- Engine Light ON (or Service Engine Soon Warning Light)
- Possible high fuel consumption
- Possible excessive smoke from exhaust
P1167 NISSAN MeaningThe heated oxygen sensor 2 (rear), after three way catalyst, monitors the oxygen level in the exhaust gas on each bank. Even if switching characteristics of the heated oxygen sensor 1 (front) are shifted, the air fuel ratio is controlled to stoichiometric, by the signal from the heated oxygen sensor 2. This sensor is made of ceramic zirconia. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. Under normal conditions the heated oxygen sensor 2 is not used for engine control operation.
