Hey Fellows. Having major issues.. a few months ago the truck died.. replaced the ECU. truck ran great then she left me on side of the road... Got her running again somehow. now the CEL comes on and goes off and comes on... I have a Snap on scanner.. According to it the voltage on the TPS is .97 closed and 4.69 @ WOT... if I put a voltage meter on the wire idle is 1.24 volts and WOT is 5.0 volts. the other thing is it won't utilize KOER with the scanner but I can pull codes using KOEO... It looks to try to go lean on the Air/fuel gauge.. Any help is so appreciated.. I was going to get another ECU but no one has one. Why am I getting Low Voltage off the ECU?
