? ?I'm new to this forum but hope someone can help me with a perplexing problem with my '03 Z66 Ava.
? ? I had to remove my battery to do some fender repair. After making the repair I reinstalled the battery. I connected the positive cable first and upon connecting the ground cable the engine started up.The ignition was turned off and the key wasn't in it. The dash was lit up like a Christmas tree the lights were on and the buzzers were buzzing.
? ? I placed the key in the ignition and turned it on and then back off but it continued to run. I managed to kill it by removing the PCM fuse.
? ? After replacing the fuse I turned the key and it stated up normally and idled right. I turned it off and didn't test drive it.
? ? ?The next day I had to once again disconnect the battery and in the process of hooking it back up it once again started up without the key. I repeated the process of removing the PCM fuse to kill it.
? ? ?I once again put the key in and it cranked up and was idling fine but it read "reduced engine speed" the tracking control light was on and would not turn off and the accelerator would not respond.? I checked for a code and it showed "P1125" in reference to the TAC. It has now started to die after idling for about a minute.
? ? ?I have looked to see if the wire harness was tight under the underhood fuse panel. beside the battery. It was tight.
? ? ?I know by the code that the PCM is not receiving the correct info from the TAC. My thinking is to replace the Accelerator Assembly since the sensors can't be replaced individually.
? ? My? dilemma is will that cure the problem or is possible the PCM is bad?
? ? Hope someone can help as I suspect this could expensive real quick.
