Knock sensor fault
- Thread starter Drew1209
- Start date
I just changed the sensor in bank 2 as that's the one that my code reader keeps picking up there's a problem with. My car always felt quite lacklustre but I just thought this was the normal but if there's a fault and it's retarding the timing I assume this will have an affect on the performance
So the fault remains with the new sensor?
Suggests to me either the wires for bank 1 & 2 sensors are reversed (if that's possible so maybe you have changed the bank 1 instead of bank 2) or possibly there's a break in the wire.
I will try have a look at my loom for you (which is out of my car on the shelf) and see if it's possible to reverse them, the plugs are identical from memory.

The plug has a notch in it so the wiring can't be reversed and the length of the wiring for both sides isn't long enough to swap over so as Harv says it may be a break in the wiring. PITA to get to though.
Find out what voltage you need to be seeing and measure the wiring at the plug and also check the ohms of the old sensor to see if it is actually faulty.
