Code P1164 Honda Description

The P1164 Honda code indicates a problem with the Air/Fuel Ratio Sensor 1, specifically relating to its range or performance. This sensor is responsible for measuring the oxygen content in the exhaust gases and sending this information to the engine control module to adjust the air/fuel mixture for optimal combustion. When this sensor malfunctions or provides inaccurate readings, it can lead to poor engine performance, reduced fuel efficiency, and increased emissions.

  • I drive a 2003 Honda Civic 2.0 Type-S, I bought a code reader to find out why the engine management light came on, it was P1164, A/F sensor, had it replaced, but the light came back on later, had it reset by my garage, but came back on again shortly after.

    What do I do now, any suggestions???

  • I have 2002 CRV, i checked connection cable and computer no problem, tried many O2 sensors, but i still have the same error code P1164, any advice?

    Reply to Comment

  • Are there any exhaust leaks near the sensor? even a small hole can cause bad readings from the sensor. There is also an update ECM software for the 2002 CRV to help address the P1164 code problem, but the updated software was released on 2011, you will need to check with the dealer if your CRV already has the new software.

  • The wired thing is some of sensors gives the error right away and some others reads correctly for few miles and then goes down, the check engine light is back on and readings are crazy

    Reply to Comment

  • If the code comes back instantly and you have new sensors, then the problem is with the wires from the sensor to the ECM, or the ECM itself. Also, just in case, I would recommend heck or replace or swap the sensor relay.

    Here are the wire colors for the sensor and relay, and below the instructions from the manual on how to check the sensor.

  • Could it be that the catalyzer is causing the problem? And need to be changed or cleaned?

    Reply to Comment

  • The P1164 code is for the Air/Fuel Ratio Sensor, which is before the Catalytic Converter, it's unlikely that the problem is the Catalytic Converter. I recommend having the dealer reprogram the ECM for you.

    Reply to Comment

  • I have two, before and after!! And most probably the after is causing the check engine error.

    Today i cleaned up the catalyzer, and i will do the reprogramming
