Engine/Transmission (1998.5 - 2002) Truck is throwing 6 codes

[DRiddel]

I got a new ECM unit put in a week ago after it went south. I put my comp back in and put a set of injectors. I am pretty sure they were there before I put my stuff on. It seems like all of the codes are ecm related. Is there any way to fix them.





P0122 (M) Accelerator Position Sensor (APPS)

Signal Voltage Too Low APPS voltage input below the minimum acceptable

voltage.



P0123 (M) Throttle Position Sensor Voltage

High Throttle position sensor input above the maximum

acceptable voltage.



P0460 Fuel Level Unit No Change Over

Miles Fuel level sending unit voltage does not change for more

than 40 miles.



P1388 Auto Shutdown Relay Control Circuit An open or shorted condition detected in the ASD or CNG shutoff relay control ckt.



P1389 No ASD Relay Output Voltage At

PCM No Z1 or Z2 voltage sensed when the auto shutdown

relay is energized.



P1693 (M) DTC Detected in Companion Module A fault has been generated in the companion engine control module.

Do the auto zone visit and ask them to clear them. If you can find someone with an ODBII scanner they can also do it.

If the ODBII does not clear the codes HAYNES Manuel says "turn the ignition key to the on position, But do not start the engine. With the key in the on position, slowly press the accelerator all the way to the floor, and then slowly release it. This ensures that the APPS calibration has been "learned" by the ECM. If the APPS calibration is not learned by the ECM, diagnostic trouble codes might be set. "
