Hi!

Have you a copy of the Haynes manual? Just thinking you can look through the wiring diagram for later models, identify the sensors and the wiring colour code for each from that - then compare to what he’s connected up.

Hope that’s some help
Andrew

I understand that, here’s a walk through example for the knock sensor.

1. Find the sensor in the index (named “Key to wiring diagrams) which is pages 12.42-12.44. Here’s the knock sensor:



2. Note the sensor number (P46) and the track number (153-154, 227) in this case and locate the page with the track number on. In this case look at 153-154 which is on page 12.45 - note the track ranges at the bottom:



3. Find the sensor on the page, following the track numbers - or just look for P46 on the page if that’s easier:



4. Note the wiring colour codes down, in this case BRWS and BRSW:



5. Look up the colour codes on page 12.23 - in this case the wires are BRown with a White Stripe (BRWS) and BRown with a Black Stripe (BRSW):



In addition to the two wires we noted there’s also a solid brown (no stripe) wire which is a ground/earth. That will be there on many/most sensors.

That’s all there is to it - so now you know that the knock sensor has two wires that are unique to it, both brown and one with a white stripe, other with a black stripe.

It’s just a case of repeating for each sensor you’re interested in.

That could be a problem, I’m not a site admin but maybe the plugin doesn’t support large files. I use Tapatalk to post/read - it has its own image support and is available for iPhone/iPad and android.

Hi ghartwell

agw9262 has offered a very good comprehensive explanation regarding the knock sensor harness......which I may add when looking at circuit diagrams gives me a "Brain Freeze" also Lol.

The only help I can offer is in relation to my Cally turbo,.............the location of my knock sensor is at the back of the engine facing the bulkhead.   You can best get at it from under the car and is held on with one bolt.    It does indeed have two wires to trigger it and it is located just above the join of the sump flange ....where it is mounted on a round machined base with the bolt hole.

Because it is a type of conductive microphone it is of paramount importance to clean this mounting base for a good signal pickup.

If not clean the new Knock sensor will not function properly.
