Vauxhall Vivaro 1.9 DCi 2004 - Keeps dying out on the throttle, code 73 #

Van keeps dying on the throttle followed by fault code 73 which refers to track 2 throttle pot had a genuine throttle pedal fitted 2 weeks ago which sorted this problem until yesterday when fault returned with same code. On live data the voltage suddenly dies to zero on track 2 then returns as if the new pot is faulty,but customer says it does it more if it,s damp??
Are there any specific areas for the wiring rubbing on these vans
Any help appreciated
Regards John

Remove metal security cover over ECM on n/s inner wing. remove ECM and check loom wiring as it bends left underneath metal housing it has a tendency to chaff against steel covers edge.
also chech loom as it runs over gearbox.

Had a few of these and each time turned out to be corrosion in multi plug on nearside inner wing. Its in the f/box area and its the engine loom connector.

Hi John
Did you ever get to the bottom of this one as i have the exact same fault with a 04 vivaro dci.Its had the throttle pedal replaced and all the wiring from it checked and wired direct.Even if we simulate a voltage direct to track 2 at the ecu the voltage still intermittently drops to zero on the tech 2.Also we swapped the ecu from another van and we still have the drop out.Any advise from anyone would be greatly appreciated.Cheers Mick.

mick
we had the same on a trafic and did the same as you
ours was the actual connector pins to the ecu the owner didnt want a loom fitted so replaced the relevant pin connectors and its been fine ever since
also even when it was fixed i noticed in live data the voltage would drop out but there was no fault with the van
we even tried tech 11 and clip on it and the voltage still dropped out
