I have a VY crewman with a L67 dropped in. . Been great til one oxygen sensor failed. .

Today I swapped the working sensor around and it works no matter what side I put it in..

Slug powered VZ, Cross 8 VZ, VE Calais & ya mum.
Recently had an O2 fault that has been tough to sort for a long time.
Relating to left rear (post cat)
Must have tried 4 or 5 4wire O2 sensors.

Cause:
The ac drain in the trans tunnel was dripping straight onto, then into, the harness to O2 connector plug.

The trans harness is hard to move much. Managed to get it to sit a cm or so in front of the drain. Seems ok so far. No short or open circuit issues.

Maybe extend the drain tube to below the O2 sensor, and wire tie it back away from the O2 connector so it wont happen again.
