Hi Eric,
This truck has a check engine light on, it's a 2.9 with a4ld auto trans, 4x4,88 model.

Thanks Frank

What scan tool are you using to scan the system?

I don't know what the name of te scan tool is, it's what they use at auto zone.

Would you be able to enter what is called a Continuous Monitor Mode (wiggle test)? IF the scanner has that function.......other wise I'll have to guide you thru an analog volt meter set up....which is a lot longer.
Erik
I have preformed a volt/ohn test and it reads code 54, however I just picked up the truck after having the trans replaced and the mechanic said that his machine says that my problem is a sensor that is in the exhaust, I don't know if he knows what he is talking about or not, and by the way I would like to thank you for helping me.

This is a VERY rare occasion where I will ask you for your alternate Email address, and I will scan and send you the volume H manual pages for that code. PLEASE don't give me Email out to any one after your vehicle is fixed. I usually don't give it out.
Erik
