Thread: Crankshaft Position Sensor Fitting

The plug is behind the passenger side head (nearer to the firewall) and is easier to get from above.

The sensor (including plug) is a 5min job. No need to take tyres or guards off, just creep under and go to town on that sucker!

From memory there's two sizes, the outer casing is small like an 8mm head, the sensor itself is a 10mm (or the other way around).

If the engine is hot, allow curse time for when you burn your hands.

Cheers for that, There are a few how to`s on Disco but apart from a vid where they take the exhaust off on a P38 for access not a lot on the PLUG. Can you remove the sender and pull the whole lot up to get at the plug or is it a knuckle fight with the head and firewall?

I read its 7mm outer and 8mm inner

That might be the case (7mm and 8mm), its been a while!

The plug is easy to get at and easy to unclip. Life is better if the car is in access height, but if it isn't just stand on a chair or milk crate. Very easy job.

I got my hand down there this morning for preliminary investigation. Think I have found the plug and should be able to release it. Dont want to mess with it till the new one arrives most probably in a couple of weeks the way the post is lately.

It is quite easy to trace from below, the wire has a silver sheath over it (mine had a bit of old engine oil on it from a previous leak somewhere which I degreased before the job).

Rangie just stopped! Engine no go!

And it was you who have me the clue to pour water over the hot sensor after it failed!

The cold water trick is general for all cars, hence the suggestion. I have a Merc with the later M113 V8 engine and they are notorious for cps failure. I now keep a spare in the boot. Never done one on a Rangie. 1st thing I did when I got home and the RR would not start was turn the garden hose on the cps, car started straight away so 90% sure its the cps. Hooked up a Rovercom on the car but no errors or anomalies. The only thing comparing it with the other car ( with a good CPS) was that the tooth count on live data with the engine running did not seem to be acting in the same way. Anyway car is parked up now waiting the new CPS. I have bought 2 so will do both cars.

The search function on here is not the best, I never came across that thread you put the link to

That's a pretty safe diagnosis! Bet you can't wait to have it going again!
