Code P1164 Acura Description
The P1164 diagnostic trouble code for Acura vehicles indicates an issue with the Air/Fuel Ratio Sensor 1, specifically a range/performance problem. This sensor plays a crucial role in monitoring the air-to-fuel ratio in the engine, providing vital information for the engine control module to adjust the fuel injection and ignition timing accordingly. When the sensor detects that the air-fuel ratio is out of the desired range or if it is not performing optimally, it triggers the P1164 code.
Common Causes of P1164 Acura
- Faulty Air/Fuel Ratio Sensor 1
- Wiring issues or poor connections
- Exhaust leaks
- Faulty engine control module
- Vacuum leaks
Symptoms of P1164 Acura
- Decreased fuel efficiency
- Engine hesitation or stumbling
- Rough idling or stalling
- Check Engine Light illuminated
- Poor acceleration or lack of power
How to Fix P1164 Acura
- Begin by using a scan tool to verify the P1164 code and any other related codes.
- Inspect the Air/Fuel Ratio Sensor 1 and its wiring for any signs of damage or corrosion.
- Test the sensor's operation using a multimeter to ensure it is within specifications.
- Clear the code from the engine control module and perform a test drive to verify that the issue has been resolved.
- If the problem persists, consider replacing the Air/Fuel Ratio Sensor 1 or addressing any other underlying issues that may be causing the code.
Cost to Fix P1164 Acura
The typical repair costs for addressing a P1164 code can vary depending on the specific cause of the issue.

What causes the P1164 code to appear in an Acura?
Common causes include a faulty air/fuel ratio sensor, damaged wiring or connectors, a vacuum leak, or issues with the engine control module (ECM).
Can I drive my Acura with the P1164 code?
While the vehicle may still be drivable, it is not recommended to ignore this issue as it can lead to reduced performance, higher emissions, and potential damage to other components over time.
How is the P1164 code diagnosed in an Acura?
A mechanic will typically use a scan tool to read the code and inspect the air/fuel ratio sensor, wiring, and related systems for damage or faults. They may also monitor live data from the sensor.
How can I fix the P1164 code on my Acura?
Repairs may include replacing the faulty air/fuel ratio sensor, repairing or replacing damaged wiring, fixing vacuum leaks, or reprogramming the ECM if necessary.
How much does it cost to fix the P1164 code on an Acura?
Repair costs vary but typically range from $200 to $400, depending on whether the air/fuel ratio sensor needs replacement or if additional repairs are required.
Can a dirty air filter cause the P1164 code?
While unlikely, a severely clogged air filter can affect the air-fuel mixture and sensor readings, so it's worth checking and replacing the filter if needed.
What is the difference between an air/fuel ratio sensor and an oxygen sensor?
The air/fuel ratio sensor is more precise and provides faster feedback to the ECM compared to a traditional oxygen sensor, enabling better control of the air-fuel mixture.
Is a software update required to fix the P1164 code on an Acura?
In rare cases, a software update to the ECM may be needed if the issue is related to incorrect programming rather than a hardware fault. A dealer or professional mechanic can confirm this.
