Hello and welcome. My name is ***** ***** you for visiting the site, I am reviewing your question and will reply shortly, thanks.
Do you have a question about the vehicle?
So sorry for the inconvenience. It seems that there could be a bad ground in the powertrain circuits. They did have a bulletin on that.
"Upon encountering powertrain DTC's, check that the powertrain main ground is good before attempting any repairs.
When diagnosing any "P" or "C" Diagnostic Trouble Code (DTC) in which normal diagnostic steps do not quickly reveal the problem, check that the powertrain assembly is properly grounded to the body/chassis/battery."
You can't check them by looking at them though.
Powertrain assemblies have at least one ground to body/chassis/battery and in some cases more.
Be aware that a quick voltage drop check between the powertrain and body/chassis/battery while at engine idle or in the shop under low load conditions may not reveal this concern. Powertrain ground requirements increase linearly (and substantially) with higher RPM/load conditions. It may be necessary to drive the vehicle under similar RPM/load conditions as when the code set while taking voltage drop recordings with a "min/max" capable digital volt meter.
That is all the information that I have on it, but wait there may be another expert who has more. I will opt out and open it back up. Please DON’T REPLY to this post as that will lock the question back to me, also DON’T RATE THE ANSWER yet, someone should be along shortly, I’m sure, thanks and sorry I wasn’t able to help with it.
Hi Im David. Instead of throwing parts at your vehicle hoping sometihng will fix it. you need to start checking wiring conditions, ground conditons, voltage outputs. voltage inputs.
just because a code comes up doesnt mean its the component.
here are some prints to assist you.
youre welcome. if you need me to let you know what you're supposed to be reading or when youre supposed to be reading sometihng on the meter or power or ground questions, im here for you.
just remember without me physically being there i may not be able to give you 100% of the answers, i.e. gorund locations etc.... but i can lead you in the right direction
do you still need assistance?
