    Default TD5 crank position sensor: Where is it mounted?

    The pic in the Rave manual does not show clearly where it is....

    I think mine is acting up. Have a new one I want to try.

    on top of the bellhousing at the 1 o clock position as seen from the rear of the vehicle. it is approx 50mm behind the cylinder head.
    on the Defender it is easy to get to once you get that thick rubber pipe out of the way.

    just for interest sake the V8 D2 sensors sits at the 8 o clock position on the face of the bellhousing

    Disappointing...

    Fitted the new one (Britpart NSC10090) this afternoon. 3min job. Engine starts but as soon as I try to rev it up it goes "grk", dies.

    Replaced old one.

    did you ensure that it is fully home?
    sometimes the o ring snags and she does not seat properly
    even if marginally high, it loses signal and dies

    Is it true that if the crank sensor fails totally, the defender won`t start at all? Thus always keeping a spare crank sensor if traveling?

    Absolutely. This part is critical.

    OK, I could feel that I was tightening the bolt against pressure coming back from the O-ring so perhaps it was not seating well. Weird though that it would idle but not run. Will try again tomorrow.

    apply a little vaseline or red rubber grease to the stem before inserting.
    have seen a couple that will start and rev to 2000 and then start stuttering and die.

    I need to learn how to replace this part. Almost left me stranded on the way back from Kruger.

    landyluvver any chance on a step by step approach to replacing this on a Disco 2 TD5?

    Its really a very simple job, 2nd time round took me 3 minutes.

    1. Remove the pipe that connects the air intake to the air filter
    2. Remove the crank position sensor (7mm 1/4" socket works best)
    3. Disconnect the plug (I found its easier to remove the CPS first, then remove the connector.
    4. Install reverse above.

    I'm confused now Why would you want to remove the air intake pipe, which is located on the left side of the engine when looking from behind, when the CPS is located at 1 o'clock, which means the right side of the engine?

    I think LRwit is refering to a defender where the plumbing is a bit different

    OK, ja on my bakkie there is a thick pipe that routes air from the intake behind the RF wheel on the fender to the air cleaner mounted on the bulkhead slightly on the passenger side. This pipe blocks the view to the CPS.

    Could the CPS cause the vehicle to struggle to start and then vibrate like an old Lister for a few seconds before it settles on a cold day?
