Freelander 1 RPM Sensor

Hi guys, I’ve got a 98 Freelander 1 with a 2.0 litre L Series engine. My rev counter keeps dropping out when the engine is hot and the engine management light comes on. There is a ‘RPM Sensor’ fault showing when plugged into an analyser.
Can anyone tell me where the sensor is located on these engines and how easy is it to get to. Thanks

One for @GrumpyGel he is the 'L' series expert!!

Quick look at manual says it is on the engine/transmission mounting plate at rear of flywheel. Simply remove inlet and exhaust manifold to access!!!!
Wow, great design.
I'd locate it and check wiring and connectors first as it is intermittent.

Erm, yeh. Its that pluggie thing with wires going to it.

Wires broke or pluggie thing.

Prolly means crank sensor - I'll have a google when I'm capable.

But I'd suggest driving only when its cold potatoes.

In other news, that 2016 Clayvin Pinot was bloody gawgus. Highly recommended. Especially when washed down with another Pinot, but I couldn't read the label by then. The Pinot Gris just added to the enjoyment. Happy times people, Freelanders are grrrrreat.

L series that is - all the other are fecking awfful.

Always a comprehensive reply from GG

Glad peeps are happy.

lol

Agreed, this is for sure a crankshaft position sensor (CKP) fault - or a fault in the wiring to it. All the symptoms are what Rave says happens when the CKP faults - also says idle will be raised.

Never touched mine, so don't know whether the manifolds need removing to gain access - but Rave is usually correct so presume they are. The CKP removal/replacement instructions are short and sweet...



Removing the manifold gasket is rather longer. Suggest downloading the Rave manual for info...

I think I'd have a look first,may be some oil on connector!!!

Just done a search to see if anyone's changed the CKP/CPS. Lots of hits, you have to filter out the non L-Series ones manually though!

Various people fixed similar faults by replacing the sensor - but I didn't find anyone describing the process - I didn't check all the hits though.

Its on the back of the engine above the IRD (if its not tucked in behind it).

There's no need to remove the manifolds to do the crank sensor. Access is tight, but it's possible to do. I changed the crank sensor on a Rover 420 with the L series engine. I'm sure I changed it from below, at least that's the way I remember it.

Thanks for the info and I hope I can get to it without stripping too much out

A 420 wouldn't have the IRD in the way (if it is).

That's true, but I can't see the sensor being too difficult to access from below.
