P0158 2007 Nissan Maxima Code - HO2S22 Circuit High Voltage

Quick Answer

The heated oxygen sensor 2 (HO2S), after three way catalyst (manifold), monitors the oxygen level in the exhaust gas on each bank. Common causes include Faulty Rear Heated Oxygen Sensor Bank 2, Rear Heated Oxygen Sensor Bank 2 harness is open or shorted, Rear Heated Oxygen Sensor Bank 2 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 P0158 2007 Nissan Maxima Description

The heated oxygen sensor 2 (HO2S), after three way catalyst (manifold), monitors the oxygen level in the exhaust gas on each bank. For optimum catalyst operation, the air fuel mixture (air-fuel ratio) must be maintained near the ideal stoichiometric ratio. The HO2S output voltage changes suddenly in the vicinity of the stoichiometric ratio. The Engine Control Module (ECM) adjusts the fuel injection time so that the air-fuel ratio is nearly stoichiometric. The HO2S generates a voltage between 0.1 and 0.9 V in response to oxygen in the exhaust gas. If the oxygen in the exhaust gas increases, the air-fuel ratio becomes Lean. The ECM interprets Lean when the HO2S voltage is below 0.45 V. If the oxygen in the exhaust gas decreases, the air-fuel ratio becomes Rich. The ECM interprets Rich when the HO2S voltage is above 0.45 V.

Frequently Asked Questions about P0158 2007 Nissan Maxima Code

1. What does the OBDII code P0158 on a 2007 Nissan Maxima mean?

The code P0158 indicates a high voltage condition in the HO2S22 (Heated Oxygen Sensor 2 Bank 2) circuit.

2. What are the common symptoms of a P0158 code in a 2007 Nissan Maxima?

Common symptoms of a P0158 code may include poor fuel economy, engine misfires, rough idling, and the illumination of the check engine light.

3. What are the possible causes of a P0158 code on a 2007 Nissan Maxima?

Potential causes of a P0158 code include a faulty HO2S22 sensor, wiring issues in the sensor circuit, a vacuum leak, exhaust system leaks, or a malfunctioning engine control module (ECM).

4. How do I diagnose a P0158 code on my 2007 Nissan Maxima?

Diagnosing a P0158 code typically involves inspecting the HO2S22 sensor and its wiring, checking for vacuum or exhaust leaks, and testing the ECM for proper functioning using a scan tool.

5. Can I drive my 2007 Nissan Maxima with a P0158 code?

It is not recommended to drive your vehicle with a P0158 code, as it can lead to decreased fuel efficiency and potential engine performance issues. It is best to address the problem promptly.

6. How do I repair a P0158 code on a 2007 Nissan Maxima?

Repairing a P0158 code may involve replacing the HO2S22 sensor, repairing any damaged wiring, fixing vacuum or exhaust leaks, or reprogramming the ECM if necessary.

7. Is it possible to reset a P0158 code on a 2007 Nissan Maxima without fixing the issue?

While you can clear the code using an OBDII scanner, the underlying problem causing the P0158 code will persist unless properly diagnosed and repaired.

8. How much does it cost to fix a P0158 code on a 2007 Nissan Maxima?

The cost of fixing a P0158 code can vary depending on the specific cause of the issue. Costs may include the price of parts, labor, and diagnostic fees, which can range from a few hundred to over a thousand dollars.
