When I bought my car, I checked the codes and saw an 03 04 and so I bought a knock sensor. I replaced it about an hour ago and all went pretty well. It was incredibly tight on to begin with and took a full two hands pressure to get off. I used a telescoping magnet for the whole process if that matters. Once we fiddled a lot with the harness it went in and we replaced the U clip. I then reset the ECU, started the car, revved to about 5-6,000 and then turned it off and checked codes to find 05 05 --NOTHING! Then I was backing out of the garage and at around 2,000RPM the CEL came on. It was never on before, it just had a code in the ECU. So I immediately turn it off and check for codes....still 05 05...I was low on gas, so I drove to the gas station around 40MPH with the CEL flashing. It says that has something to do with a misfire...I checked codes again and still 05 05. I am really upset, I dont have any money to bring it to a dealer. Ive looked over everything and I dont see any loose connections or anything. The sensor is snug, but not TIGHT as before, it is a good one hand of pressure. What do I do??? Please help!

 

By the way, I now have full gas and checked the grounds. Im sitting here waiting for an answer so please help.

Check the plugs on all your coil packs and injectors.

You upset something while you were working on the KS.
