Hi all
Was on servicing my car (corsa b 1997 1.4 8v) and plugged my code reader in to check the codes and found this code p1640, driver 1 input voltage high. I was just wondering if anyone could shed any light on what this means, and what the fault is?
Many thanks
Steve

Just googled it :laugh: problems with EGR came up alot although it doesn't say exactly what the problem could be. Vauxhalls like to give you random codes now and again though too

Hi there, I googled it too and I've found a few hits saying it could be the ecu :( I've tried resetting it (had it unplugged for half an hour) checked fuses...
The car itself runs ok, only thing is I've noticed is the engine check light doesn't light up at all
