Thread: Engine stopped - won't start - Looking for ideas

Country mechanic did have a fault code reader - the following info is what I've been given - I was sent a pic of the report but it has details on it I don't wish to share so below is the relevant info.

P0405 Exhaust Gas recirc
P1355 Refer official manual
P140A Refer official manual
P140D Refer official manual
P140E Refer official manual
P0494 Refer official manual
PO342 Refer official manual
P0046 Refer official manual
P0341 Camshaft position sensor

Does the cam position sensor fault shut the engine down - that's the one that stood out to me.

TIA

Realising that the D3 can generate lots of unrelated faults so this could just be a total coincidence - but at least 8 of the above fault codes can be caused by a short circuit to ground.

There are 4 EGR related faults, a Turbo boost control fault, a Viscous Fan fault, and two Crankshaft Position Sensor faults all which could be due to individual sensor failures or a short circuit to ground.

Ideally now you want to be able to clear all faults, then see which comes back first.

The crankshaft position sensor though should be the only fault in that list that stops the engine running.

Check the wiring schematic, they could be on a common power supply, one short can take down multiple circuits, giving you all those faults

Check all the engine bay fuses and fusible links too.
The sensor earths are provided by the ecm so possibly a fault with one of the ecm earths.

Sorry to be old fashioned, but suck, squeeze, bang and blow was pretty easy to diagnose. It's when they want tinsel and tissue paper that it fails.

I'd be thinking wiring issue / ECU failure as well.

Might be awkward to diagnose, had they recently been through water or a car wash?

Graeme and shack raise good points.

May be worthwhile also pulling the transfer case module, and the engine ECU behind it and checking plugs for evidence of water or corrosion as well.

Water in this area has been known to generate lots of faults and prevent an engine starting. Worst case is the ECU has failed.

Here’s hoping it is something simple (like a bad earth).

Haven’t had a chance to get an update today - will check later on but I think it was towed to LR.

Better to go to a good Indie.....

Someone no doubt will tune in with one in the area.
