hello all jimbo here, i have a 1998 accord f23a1 5speed and im throwing the knock sensor code, so i replaced it and drove it around allllllll week and the code will not go away, i disconnected the battery for a bit, checked it with a multimeter and cleared the code with my scanner but still comes back on, any ideas of what to do next? btw the car has 169K miles if that helps

 

It's the wiring. Check for continuity from the connector back to pin D3 at the ecu connector.

 

well tested the wire and that is fine.

 

Have you verified the timing is correct?
Use a stethoscope, or large screwdriver, or broom stick and place it against the block and the other end against the side of your head near your ear. Do you hear any knocking or other noises?

 

If you're sure the wiring it correct and the knock sensor is good then the next thing would be a substitute ecu if you can find one.

 

they are sending me out another sensor in case this 1 is defective and if that doesnt fix the issue then ecu will be inspected for any burnt marks and if that doesnt work then off to the service station

 

What is the exact diagnostic code that you are getting?

If wire is fine and sensor is good should start looking at your ignition timing and fuel. Check your spark plugs and see if any of them are really black or chalky white.

 

P0325 is the code im getting, im just waiting for the replacement from the company i bought it from and go from there. thanks everyone for your comments and suggestions.

 

There are only three listed issues for that particular DTC.

• Short/open in knock sensor circuit
• Knock sensor
• ECU

Good luck! Hope it was just the sensor
