hi,

ive just done a ecu diagnostics check and error 34 appears. this relates to knock sensors.

according to the manual, each sensor at the ecu should read approx. 4v. my first sensor reads 3.8v (acceptable), however the second sensor reads 7.8v. this is out of range by quite a lot...

does this mean the sensor needs to be replaced, or there is a problem somewhere along the wire connection between the sensor and ecu pin?

also, how hard is it to change a knock sensor? i know where they are, and they arent that easy to get to. is it a hard job, or just a matter of unscrewing them?

will there be oil spillage when they are taken out?

thanks heaps for any help
