P1163 2003 NISSAN ALTIMA SEDAN - Heated Oxygen Sensor 1 Lean Shift Monitoring Bank 2
P1163 2003 NISSAN ALTIMA SEDAN Possible Causes
- Faulty Front Heated Oxygen Sensor Bank 2
- Faulty Front Heated oxygen sensor 1 heater
- Fuel pressure
- Faulty Fuel Injectors
- Intake air leaks
P1163 2003 NISSAN ALTIMA SEDAN Tech Notes
If there are no intake air leaks, the most likely cause of the P1163 code is the front O2 sensor bank 2.
Cost of diagnosing the P1163 2003 NISSAN ALTIMA SEDAN code
The cost of diagnosing the P1163 2003 NISSAN ALTIMA SEDAN 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 P1163 2003 NISSAN ALTIMA SEDAN code detected?
The maximum and minimum voltage from the sensor are not reached to the specified voltages.
P1163 2003 NISSAN ALTIMA SEDAN Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P1163 2003 NISSAN ALTIMA SEDAN Meaning
The heated oxygen sensor 1 is placed into the front tube. It detects the amount of oxygen in the exhaust gas compared to the outside air. The heated oxygen sensor 1 has a closed-end tube made of ceramic zirconia. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. The heated oxygen sensor 1 signal is sent to the ECM
. The ECM
adjusts the injection pulse duration to achieve the ideal air-fuel ratio. The ideal air-fuel ratio occurs near the radical change from 1V to 0V.
