I recently pulled a P0325 knock sensor code, from my personal code scanner as well as Honda themselves, so I replaced it. Cleared the codes and within 3 miles the check engine light came back on. Pulled the same code immediately, P0325. I bought a cheap knock sensor off of ebay, so I thought that it was just a piece of **** and replaced it again. Same results, and I just took it to a shop who has told me that they are getting correct readings on the connector and the knock sensor itself. WHAT COULD BE THE PROBLEM???

I am also pulling a P1259 code, which is vtec malfunction, just so you know. I don't know if these codes would have anything in common or work together in any way.

Could this be a timing issue? I have a new timing belt and water pump ready to be done just haven't done it yet until I pass emissions, but with the two codes im pulling I won't be able to. If you have any suggestions or experiences with this, I would really appreciate any ideas. Thanks Htech-ers!!!

If the sensor is good and you're getting correct voltages at the connector then something is wrong with the ECU.

or intermittent open ... check for voltage on the wire while wiggling the wiring at the connector and ecu wiring

Well I hope it's not the ecu! I changed the oil, just to make sure that it wasn't the oil level throwing those codes. After that I drove it for a day, about 150 miles or so, and the car drove amazing with no check engine light coming back on. Light just came back on, but I'm not pulling the knock sensor code, just the P1259. This code has to be intermittent! The stuff you guys have mentioned to check I have never messed with before, so I might have to have someone check it out for me. Thanks for all replies.
