1989 CPS (crankshaft position sensor)

I’ve often thought about replacing the original CPS in my '89 XJ40 but never got around to it. But after reading Mike Stone’s post (My '94 Died At a Stoplight and Wouldn’t Restart) I decided to order one.

Much to my surprise it seems that new sensors for the 88-89’s are around 3 times as expensive as other years, over $300. Anyone know why ? Are there less pricey alternatives ?

Dennis, I found this on ebay. There’s one 4* review because apparently the plug was different. You need to find out if this sensor is a 3 wire one. The CPS for the X300 cars are cheap but they’re 2 wire sensors.

The expensive price is the reason I haven’t replaced mine. Since mine barely gets driven anymore, it doesn’t make sense for me to buy one as a spare.

I agree with Joe that its worth checking ebay. There’s so much competition on that site that you get can some great deals on parts.

WOW thanks Joe …

$23 vs $320 is a BIG difference ! I’ve sent the seller a text to find out how many wires it has.

I searched online and can’t understand why the CPS sensors for an '89 XJ40 could be so-o much more expensive than for all the other years and different makes of cars. They look exactly the same and do exactly the same job.

Of course I always expect any part with Jaguar in it’s name to be more expensive but this is ridiculous.


I wondered if this would fit as well.

This is the same but made by Prenco.

FAE and the OEM Bougicord also make the same sensor for Volvo for higher price.

The holstein one is a 3-wire - you’re in luck, just switch the plugs …here’s an even cheaper one on Amazon, check out plug photo

… and only 16 bucks and change on rockauto …


Folks, I don’t know about the '89 models (3.6 engine) but this would be ‘wrong-handed’ for a '94 model (4.0 engine) as the mounting bolt for the sensor on my '94 is on the radiator side of the sensor when installed - this one has it on the engine block side.

Big loop coming up then Mike! :woozy_face:

good spot!

Yeah, this right angle design would not work, there’s a chance the wires would press against the bracket too hard or even prevent the fitment of the sensor.

Well as you may know from one of my very recent posts I have had reason to become intimately familiar with my CPS! :sweat_smile:
