Hi all - I finally pulled together the funds to purchase a tech 2 and got stuck into the beast today. There were a bunch of DTC - one related to the MAF (which doesnt exist in this build) and one related to the O2 sensors which have to be upgraded from VY to VZ so nothing we didn't know there.
Other codes:
P0200 one related to an injector malfunctiuon - will need to investigatge but she starts and idles then drops off severely and barely runs.
P2120 and 2125 - both related to the Accelerator Pedal and the cause of it going into limp mode.
I checked continuity and the pin outs from the TAC to the pedal and all are correct. Installed a new connector for the pedal while I was at it. The trouble is that the pins to the voltage divider are 1. 2 and 8 and 5, 7 and 3. (edit - this is incorrect information - the pin numbers in the manual are incorrect) The "genuine" LS1 pedal (part number 92183447) I can't find. I have checked a couple oftimes with Holden and they tell me the part number does not exist in their system. The pins for the correct version are 1,2 and 8 and 7, 6 and 3. The pins with reistance readings in the pedals I have are 1, 2 and 5 and 6, 7 and 3 (edit - this is incorrect information - the pin numbers in the manual are incorrect). eBay currently has one listed as belonging to a crewman LS1 - but according to the manual there is no difference between pedals. The only difference I am aware of is one part number comes with a sports pedal and the other doesn't.
If anyone knows what accelerator part number 92183447 is off it would be greatly appreciated (edit - it is off an LS1 powered crewman) if you could let me know so I can unload the crap I have been sold to someone who needs them. If by chance you have an accelerator pedal part number 92189343 please let me know. I am keen to bring this old girl back to here best and don't want to change her to a cable system unless it is absolutely necessary.
Cheers
Craig
