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 https://www.fordxr6turbo.com/forum/topic/96609-knock-sensor-2-fg-xr6t/ Share on other sites More sharing options...

That's probably what needs to be done. Link to comment https://www.fordxr6turbo.com/forum/topic/96609-knock-sensor-2-fg-xr6t/#findComment-1710522 Share on other sites More sharing options...

Seems I was 1min late in burning keith... Link to comment https://www.fordxr6turbo.com/forum/topic/96609-knock-sensor-2-fg-xr6t/#findComment-1710526 Share on other sites More sharing options...

Sounds like you need to check the rear knock sensor. 1 Link to comment https://www.fordxr6turbo.com/forum/topic/96609-knock-sensor-2-fg-xr6t/#findComment-1710527 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"...

The rear one is hard to get to unless you have a very long skinny arm or a hoist.
