Hi, I'm Wayne.

I'll be assisting you with this issue today.

Thank you for coming to Just Answer

Your Question is as important to us as it is to you.

Just Answer might prompt you for a phone call,

that request is not from me and is not necessary.

What you are describing is the TPS (throttle pedal sensor).

It is located in the cab on the throttle pedal 3-4 wires plug into it.

I suggest replacing that.

NoECM fuses are good1 on driver side firewall and one inside fuse panel on passenger side
Technician: Wayne, Journeyman replied 3 years ago

Hi

Thank you.

You have a ground issue to the ECM or the ECM has an issue.

Remove and clean the plug harness. If still the same, remove the ECM and have checked.

I hope this helps you.

Put new ECM on , no change
Technician: Wayne, Journeyman replied 3 years ago

Hi

OK, that then says you have a ground issue to the ECM.

You're going to need an ECM pinout and trace wires.

I was hoping more for troubleshooting steps rather than just schematics
Technician: Wayne, Journeyman replied 3 years ago

Hi,

The troubleshooting steps are from the diagrams.

It gives you the pins to test.

Without a serial number, it is tuff.
