Engine/Transmission (1998.5 - 2002) Do not understand what these 3 codes mean

[mules4me]

I have just installed my Edge comp without hooking up the pump wire. I did not get a good ground the first time. Now I show three codes set and the check engine light stays on. What do these mean and what should I do about them.

P1693 - DTC detected in ECM or PCM

P0238 - Map Sensor voltage too high

P1478 - Aux 5 volt output too high



Thanks for any advice

Use a code reader or disconect both batteries and turn the key on for an hour or so to clear the codes and run it. The bad ground caused them.

Thanks BodyBomber: I unhooked the batteries and let sit for couple hours and now the check engine light has gone out. Will see if the codes are gone as soon as I get back out there.

Thanks again for advice.
