Hello all CRD enthusiasts!
The problem is as the title suggest, but I have a hard time putting into words what it does. This problem only happens when its cold and for about 5-10 minutes. In that time, it only happens when its in gear or has some harder load like going up a hill. If its in park or neutral, it doesn't do it. Also, if it stutters a couple times in a row, the temp gauge will spike, but then go back to normal. Once in gear and I take off from a light, it runs fine.
It has yet to throw any codes and doesn't puke out any smokes when it does this.

The vehicle has 192K (Engine has 25K on it) but the fuel injection pump is original. Any thoughts? Sorry if I am not explaining this very well, but will do my best to answer any questions. Thanks!

Ken

are you having to top off the coolant, mysterious disappearance?

Could be either the ambient temp sensor or air intake sensor failing and thereby confusing the ECM.


I would check the connections on these sensors or replace them and re-plug the connectors on the ECM with battery disconnected.

Whenever I see a post regarding a LHD 2006 CRD I have to mention the well known possible fault where the Fuel Filter Mounting Bracket presses down on the wiring harness going behind it!

This could cause fraying of the insulation and thereby shorts down to chassis or shorts between two random wires.....so it is advisable to remove this bracket and inspect the wiring in that area for any damage. :wink:

Almost certainly an electrical fault.

The way it happens between cold and warm and doesn't set a code sounds like a crankshaft position sensor starting to go bad. These are notoriously hard to pin down as symptoms vary.

I've never heard of one causing a temp gauge to spike though. This sounds more like a bad connection, loose ground, or, as noted, a short or ground within the loom.

Once in about 3 years, so basically no

I would replace the crank sensor as a preemptive measure to rule it out. :wink:
They are notorious for causing strange problems during the warmup phase of engine operation and most times never trip a DTC. :roll:

Thanks! Are they difficult to replace or expensive?

Neither,
can be replaced from underneath quite easily. Search on LOST; there are threads that describe exactly how to R&R it.
Cost, about $50 bucks at Autozone and the part that comes in the Autozone Duralast box is the OEM Bosch part.... :wink:

See section 14, page 81 in the Factory Service Manual for R&R instructions.
Note: FSM says to drop exhaust pipe, but that is not necessary. Sensor can be changed by working around pipe, there is room.
Picture below shows Crank Sensor location. There is a small heat shield you have to remove to see and access it.
