D2 td5 - starts, then limp mode

Loaded up - normal select drive, motor away! Nix flash, wheel spinnin' stuff.

EAT is very sensitive to voltage drops, if battery is low will get M&S flashing prior to or during turning the engine over; if it starts alright but spikes down on revving up it could certainly be the alternator.

If the CAN bus comms are missing or interrupted the EAT will go immediately into limp mode. Reading EAT fault codes with Nanocom will tell.

Also possibly overboosting, usually boils down to a leaky/parted/disconnected wastegate hose.

Well, the son's car went onto the trailer and I floated it back to Melbourne. If you saw me and my shadow on the Western Highway at any stage on Friday afternoon, and I annoyed you with 85 km/hr, I'm sorry, but it was a safe trip.

Why was it trailered?

Insert 1000aH cranking battery.

1. I replaced the accelerator assy, plugged it in. Now how does reading the type of accelerator link with the new installation? Any hints?

2. The thing ran badly enough in limp mode BEFORE I changed the assy, when it sometimes starts, then runs for a bit (20 sec or so), then starts to miss, running on 4,2 then stalls, and refuses to restart.

3. Engine malfunction light comes on. Fault reads "17.03 High speed cranck" (sic). Clear it, crank engine to attempt start, and back the fault comes.

Where to look, oh magi?

Cheers

If its happening when under full load,check the boost on Nanocom in instrument mode.1.4bar or higher and you will get fuel cut out firstly then limp home.Worth grabbing a turbo boost modulator before you go,it may be stuffed,less than $50 for a newie;);););)

Throw a new crank angle sensor in,they are cheap.
There was a post in the last few days showing a D2 TD5 wiring loom that had chaffed on a ACE line,worth checking that too.

Well, it turned out OK in the end. Replaced throttle pot and reset it with Nanocom. Still misfire, then it stopped and I could restart it. CKP sensor, I thought. So in with a newie, and then on a weird thought - check the harness to the sensor - I did just that.

I wish with all my heart to find whatever dribbler mashed this harness. It's shielded nearly to the plug, and a couple of pigtails pick up the positive clip plug onto the sensor, usually.

This one had been monstered by having a couple of mismatched terminals on each side of a botched repair on the plug. The only good bit was the shrink tube on the supposed repair!!! Only one strand of the cable was partly attached by solder on one side of the plug, and 5 strands on the other. Cut and shut the loom with a replacement plug....

Voila!!! Instant start!!!

Cleared all the remaining faults. The thing goes like a train!!!

How clever am I?

Thanks to those who pointed me in the right direction.
