P0132 2008 Nissan Altima Sedan Code - Air Fuel Ratio Circuit High Bank 1 Sensor 1
Quick Answer
The Air Fuel Ratio (A/F) sensor is a planar dual-cell limit current sensor. Common causes include Faulty Air fuel ratio (A/F) sensor 1 bank 1, Air fuel ratio (A/F) sensor 1 bank 1 harness is open or shorted, Air fuel ratio (A/F) sensor 1 bank 1 circuit poor electrical connection. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P0132 2008 Nissan Altima Sedan Description
The sensor is capable of precise measurement λ= 1, but also in the lean and rich range. Together with its control electronics, the sensor outputs a clear, continuous signal throughout a wide range (0.7 < λ < air).
The exhaust gas components diffuse through the diffusion gap at the electrode of the oxygen pump and Nernst concentration cell, where they are brought to thermodynamic balance. An electronic circuit controls the pump current through the oxygen pump cell so that the composition of the exhaust gas in the diffusion gap remains constant at λ = 1. Therefore, the A/F sensor is able to indicate air/fuel ratio by this pumping of current. In addition, a heater is integrated in the sensor to ensure the required operating temperature of 700 - 800°C (1,292 - 1,472°F).
What are the Possible Causes of the DTC P0132 2008 Nissan Altima Sedan?
- Faulty Air fuel ratio (A/F) sensor 1 bank 1
- Air fuel ratio (A/F) sensor 1 bank 1 harness is open or shorted
- Air fuel ratio (A/F) sensor 1 bank 1 circuit poor electrical connection
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks may be faulty
- Exhaust gas leaks
How to Fix the DTC P0132 2008 Nissan Altima Sedan?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

Frequently Asked Questions about P0132 2008 Nissan Altima Sedan Code
1. What does the OBDII code P0132 indicate on a 2008 Nissan Altima Sedan?
The code P0132 indicates that the Air Fuel Ratio (AFR) sensor in bank 1, sensor 1 is sending a higher voltage than expected, suggesting the engine might be running too rich.
2. What are common symptoms of the P0132 code in a 2008 Nissan Altima?
Common symptoms include a check engine light, poor fuel economy, rough engine idle, or a noticeable decrease in engine performance.
3. What could cause the P0132 code to appear in a 2008 Nissan Altima?
Potential causes include a faulty air fuel ratio sensor, exhaust leaks near the sensor, shorted wiring or connectors, or an issue with the engine control module (ECM).
4. How can I fix the P0132 code in my 2008 Nissan Altima?
Repairs might include replacing the air fuel ratio sensor, repairing any exhaust leaks around the sensor, fixing wiring issues, or potentially replacing the engine control module if it's faulty.
5. Is it safe to drive my 2008 Nissan Altima with the P0132 code?
While you can usually still drive the vehicle, it's best to address the issue promptly as driving with a rich running engine can lead to other problems like catalytic converter damage.
6. How do I verify that the air fuel ratio sensor is the problem with code P0132?
Verification can be done by checking the sensor’s output voltage with a scan tool to see if it's consistently higher than normal. Further diagnostics might involve inspecting the wiring and connectors for damage or shorts.
7. Can a P0132 code cause my 2008 Nissan Altima to fail an emissions test?
Yes, since the P0132 code indicates a problem with the air-to-fuel mixture, which can increase exhaust emissions, it can cause the vehicle to fail emissions tests.
8. What maintenance should be performed to avoid encountering the P0132 code?
Regular maintenance should include checking the condition of the air fuel ratio sensor and associated wiring, and ensuring there are no exhaust leaks, especially near sensors.
