Engine/Transmission (1998.5 - 2002) Weird codes, COMP maybe???

[Mactruck]

just recently I pulled my truck off the road to do some minor engine work.



I put it all together including a new comp.



and I got some funny codes.



P1693

DTC Detected In ECM Or PCM (I know this always comes up but wait)



P0523

Oil Pressure Voltage Too High

P1475

Aux. 5 Volt Output Too High

P0238

MAP Sensor Voltage Too High

.



I'm going to pull the comp off to see if this helps the problem.

I also reset my APPS, cleaned the IAT sensor, and replaced the batteries.



When I drive it, it is VERY SLUGISH.



What do you guys think?

Make sure ALL of the grounds (Comp, engine, body, frame, etc) are all good. I had several codes pop in after the Comp install, including the MAP and 5v, but nothing since I regrounded the comp to the battery. Seems all of those codes are voltage related, coincidence?

You are right!.

I have grounded my Comp to the battery but when I replaced the batteries the ground got disconnected.

It is reconnected and codes are cleared. Thanks a bunch!

no prob, that's about the fourth or fifth time that's been the issue. took me several months to clear mine, I think it was a combo of the comp ground and a loose ground to the block...

Glad it's gone!
