So swapped sensor with a known hood one from a ba turbo. Same part number etc. It's only has the one sensor on it so mechanic swapped it for him. Used a snap on scanner and no code showed Today I scanned it with forscan and had code come back again. Also a knock sensor 1 code aswell ...... This car does not have 2 sensors...why does it keep saying this and also now other code ? Car goes fine...is modified but drives...looks imaculant Link to comment Share on other sites More sharing options...

That's probably what needs to be done. Link to comment Share on other sites More sharing options...

Seems I was 1min late in burning keith... Link to comment Share on other sites More sharing options...

Sounds like you need to check the rear knock sensor. 1 Link to comment Share on other sites More sharing options...

Having the worst memory in the history of men makes me susceptible to "what was I just talking about" and "what's that tool you turn the cork screw thingy on to undo a nut or bolt"... CRAFT in other words! Link to comment Share on other sites More sharing options...

The rear one is hard to get to unless you have a very long skinny arm or a hoist. Link to comment Share on other sites More sharing options...
