Code P1164 GMC Description
The P1164 GMC code indicates a problem with the HO2S (Heated Oxygen Sensor) Bank 2 Sensor 3 in the vehicle. This sensor is responsible for monitoring the oxygen levels in the exhaust gases to ensure the proper air-fuel ratio for combustion. When the sensor detects that the air-fuel mixture is too rich or there is a high voltage reading, it triggers the P1164 code.
Common Causes of P1164 GMC
- Faulty HO2S Bank 2 Sensor 3
- Vacuum leak in the intake system
- Malfunctioning fuel injector
- Issues with the engine's air intake system
- Wiring or electrical problems in the sensor circuit
Symptoms of P1164 GMC
- Rough engine idle
- Decreased fuel efficiency
- Hesitation or stalling during acceleration
- Check engine light illuminated
- Increased emissions levels
How to Fix P1164 GMC
- Diagnose the root cause of the rich condition or high voltage reading using a diagnostic scanner.
- Inspect the HO2S Bank 2 Sensor 3 and replace it if faulty.
- Check for any vacuum leaks in the intake system and repair as necessary.
- Test the fuel injectors and replace any that are malfunctioning.
- Inspect the engine's air intake system for any issues and address them accordingly.
Cost to Fix P1164 GMC
The typical repair costs for addressing a P1164 GMC code can vary depending on the specific cause of the issue. Parts such as a new HO2S Bank 2 Sensor 3 can range from $50 to $200, while labor costs can range from $100 to $300. Overall, the total repair cost for this issue could range from $150 to $500. It is advisable to check with local auto repair shops for more accurate pricing based on your vehicle's make and model, as well as the severity of the problem.

Frequently Asked Questions about P1164 GMC Code
What does the OBDII code P1164 mean on a GMC?
The P1164 code indicates that the Heated Oxygen Sensor (HO2S) on Bank 2 Sensor 3 is detecting a rich condition or high voltage beyond the expected range.
What are the common symptoms of a P1164 code on a GMC?
Symptoms may include poor fuel economy, rough idling, loss of engine performance, a lit Check Engine Light, or increased exhaust emissions.
What causes the P1164 code to appear on a GMC?
Common causes include a faulty HO2S sensor, wiring issues such as short circuits, a rich air-fuel mixture, a malfunctioning fuel injector, or problems with the engine control module (ECM).
Which sensor is Bank 2 Sensor 3 in a GMC?
Bank 2 Sensor 3 refers to the third oxygen sensor located on the side of the engine opposite the first cylinder (Bank 2) and downstream in the exhaust system.
Can a dirty air filter cause the P1164 code on a GMC?
Yes, a dirty air filter can contribute to an overly rich air-fuel mixture, potentially triggering the P1164 code.
How do I diagnose a P1164 code on a GMC?
Start by inspecting the HO2S sensor and its wiring for damage. Use a scan tool to monitor sensor voltage readings and check for rich air-fuel mixture conditions.
Can I drive my GMC with a P1164 code?
Driving with a P1164 code is not recommended, as it can lead to poor fuel efficiency, increased emissions, and potential damage to the catalytic converter over time.
What tools are needed to repair the P1164 code on a GMC?
You may need an OBDII scanner, a multimeter for testing electrical connections, and basic tools to replace the oxygen sensor if necessary.
How much does it cost to fix a P1164 code on a GMC?
The cost can vary, but replacing a faulty oxygen sensor typically ranges from $100 to $300, including parts and labor.
Can a faulty PCM cause the P1164 code on a GMC?
While rare, a malfunctioning Powertrain Control Module (PCM) could potentially cause the P1164 code by misinterpreting sensor data. Always rule out other causes first.
