  • Getting code p0339 on 09 Accord. Part shop ran it and said it is crankshaft position sensor. I can replace it but dont have device to clear code. Will it hurt to replace and drive it to have code cleared.

    Reply to Comment

  • After you replace the sensor, you can just disconnect the car battery for about 30 min to clear the code. Nothing will happen if you don't clear the code, eventually the light will off by itself (may take several weeks)

  • Do you need to do a crankshaft relearn?

    Reply to Comment

  • 1. Start the engine. Hold the engine speed at 3,000 rpm (min ?1 ) without load (in neutral) until the radiator fan comes on.

    2. Test-drive the vehicle on a level road: Decelerate (with the throttle fully closed) from an engine speed of 2,500 rpm (min ?1 ) down to 1,000 rpm (min ?1 ) with transmission in 1st gear.

    3. Test-drive the vehicle on a level road: Decelerate (with the throttle fully closed) from an engine speed of 5,000 rpm (min ?1 ) down to 3,000 rpm (min ?1 ) with transmission in 1st gear.

    4. Repeat step 2 and 3 several times.

    5. Turn the ignition switch OFF.

    6. Turn the ignition switch ON (II), and wait for 30 seconds. The CKP pattern learn procedure is complete.

  • Hi, I attempted the relearn process above, no luck. I bought the Honda Accord OEM part (37500-R40-A01Sensor Assembly, Crank) replaced it and it self corrected.

    Additional, I drove it for a day, check engine light turned back on. I reset the code (I did not due previously) and now it runs good. However, the light came back on, I ran the code reader and resulted with P0139 HONDA - HO2S Bank 1 Sensor 2 Slow Response. I am replacing it ASAP.

    Can anyone give me a detail location for it (photos/diagrams)?

    Thank you
