Mines bolted down....where did it go??? Just kidding. There is nothing to the sensors..have you checked the wiring?? A bad connection would be more likely. What makes you think it's that sensor and what are the symptoms??

won't run, ECU is throwing a fault code that says the crank angle sensor is the issue. I'm trying to test the wiring now with not much success. At the mo the continuity tester shows NO connection between the sensor plug and the ECu plug. 🙁

I'm hoping I have the wrong terminals, otherwise I'm gonna have to trace it back through the loom. 👎

can you bridge the wire from the sensor to the ECU to confirm?? (bypass the loom) Might speed things up a little....if you can it will confirm the sensor is dead or the wiring is u/s.

Hi,
They are a pretty bullet proof bit of gear, be surprised if it is RS, shouldn't be too hard to trace though. The can and crank sensors are the lot of 3 wires with the grey sheilding which goes pretty well alll the way up to the ECU.

Is it missing/backfiring when u try to start? sure you haven't slipped a timing tooth?

I think you would need to run both wires...you can check with a multimeter to see if the sensor is working if it is a pulse sensor....remove the sensor and connect your multimeter + and - to the wires from the sensor..the order doesn't matter. You are trying to detect if the sensor is putting out a voltage which you are about to make by waving a screwdriver past the sensor head quickly ,trying to simulate the movement of the pickup on the crank. Check to see if a voltage is present..the numbers on the multi should move up and down/fluctuate.You could try this with the sensor still in the car and by cranking the engine if you want to do it the easy way......but you will need long arms to reach the starter,or a helper. If that checks out OK dive into the spaghetti and check connectors.🤪

no idea what the EJ sensor is like, but this document for my V6 may be of some help (possibly);

http://www.offroadvw.net/bajawes/KLZE/reading%20malf%20codes.pdf

If you read down to code 2 you will see it is the crank angle sensor. On my V6 it has 2 of most sensors, so if the crank sensor dies it ignores it and runs off the sensor in the distributor.

The document does describe things to test, and resistance to measure. This will only help if your sensor is a similar type...

I've heard of this problem quite a few times on various forums, but all times it's been a fault somewhere else in the system and not the sensor. I have a spare if you want to confirm.

Newsflash: the wiring was fine, the sensor was not.

Just got a 2nd handy, $88 🙁

Let yáll know how it goes.

All good, plugged it in, bolted it down and it fired up straight off. Sensor came off an Ej22, just goes to show Ej22s are good for something. 😀

BTW, thanx for the call today Mick. Now I know why you spend so much time on the forum.😵
