AUII knock sensor

Anyone had trouble with the knock sensor in an AUII? I keep getting code PO3325 when I do a code check (knock sensor out of range). When it is cleared it takes about a week of driving before it reappears. I first thought I had logged the code by hitting the speed limiter (oops) a couple of times, but havent done this lately and the code still logs. At times it seems a bit gutless until 2000 rpm then it takes off. The only spec I can find for the sensor is that the resistance should be >10k ohm. Mine's about 4.5mega ohms.

Re: AUII knock sensor

this may sound funny but.... un bolt it and clean the bolt and shaft it sits on make sure there is no corrosion on any thing..... I havnt had any experance with au knock sensors but some use the mounting bolt as an earth.. if u get any high resistance there it could throw it out of range.. But im pretty sure the au ones are a 2 wire one (own earth) so this could be usless information any hows its worth a trie i gues.

Re: AUII knock sensor

Yeah, already tried that. It is a two wire sensor but like you said, anything's worth a try. Thanks.

Re: AUII knock sensor

Could someone tell me where the knock sensor is located and is it hard to remove?

Knock Sensor
The Knock Sensor is on the left side of the engine under the intake manifold near cylinder #5

Re: AUII knock sensor

I think you'll find that the bolt will be loose or excessively tight which throws the readings off. Make sure the knock sensor bolt is properly torqued to the correct value.

Re: AUII knock sensor

Hadn't thought of that, thanks. Any idea on the correct torque?
