The shop replaced the CKP sensor. It didn't fix my misfire problem, but was a step in the process of elimination, and another part to replace on the list of preventive maintenance for this high mileage (166K) vehicle. Diagnosis continuing.

 

Did you have a code indicating that the CKP sensor was faulty? I'm doing a mid-life reliability update on my LR2... is the CKP a known point of failure.

 

I did not have a code indicating it was faulty. I watched a Youtube video where the guy explained that codes for the camshaft and crankshaft sensors only appear if they are completely dead. You will not see a sensor code if they are faulty but still sending a signal, even if it's a bad signal. In that case, the only codes you will see are related to the symptoms (e.g., misfires).

I have not heard that the CKP sensor is a known point of failure. It was just on the list of things to consider if you have a misfire condition.

It's inexpensive, the OEM sensor can be found online for as little as $35 USD. The difficulty is getting to it, at least for the gasoline engine. So if the car is on a lift for any other reason, you might consider replacing it at that time to take advantage of the access opportunity.

 

LR2driver: I see this is a 4 year old post, but you are still active on the forum. Do you have any photographs or directions how to get to the CKP sensor on a 3.2 i6 LR2 (FL2)?

 

I took it to my local LR2 independent shop and they replaced it. This was one of those times the "right tool for the job" was a lift and some helping hands. Sorry I don't have more for you.

 

Did you look at post #6 and the posts above it?

 

Yep, more than I could do in my carport.

 

Yes, that is why I posted the question asking if anyone had a photograph and/or steps required to access.
To get to the sensor, what has to come off, or is it merely crawling underneath or putting up on a car hoist and looking from below?

The OP sent me a PM saying in the end he took it to a workshop. For me, taking to a workshop involves a $200 ferry ticket and a day there and back, so I would rather DIY

 

There is more than one video showing the procedure on YouTube. The videos are mostly for diesel models but the work is not much difference for gas engines. Here are a couple of examples. This is not a "holy cr@p, what did I get into!?" job. Both of these dudes did it in their driveways!

 

As you can see on the back of the first video, it shows TD4 on the back of the car. It's a diesel. The second video does not show the car, but the sensor fits in the same place as the first. I found both videos and kept hitting the stop key, running back and forth to the FL2 until I realises the first video showed it was a diesel. Seems in UK, most are diesel whereas in New Zealand, most are imported 3.2 I6 petrol from Japan or NZ new petrol. Finally found this post which said the petrol sensor is in a different and harder to access location, but unfortunately, the OP put it in the too hard basket and took it to a mechanic.

There really is a big difference between the locations for petrol vs diesel.

I would say I spent half an hour doing various google searches before asking for help on this forum.
