Engine/Transmission (1998.5 - 2002) Comp = check engine/ fault codes?

[HOSS]

I just installed my PE comp in place of my EZ yesterday. On my way to work this morning the check engine light comes on. I do a check, the PCM shows P-1693 and the ECU shows P-0237 can anyone give me any insight into what they translate into?

The truck has run flawlessly until now, never had a fault code or check engine before. I have the PE boost elbow in place so it sould not be an overboost code.

The truck has no performance issues right now. It runs fine, starts and shows no signs of any problems accept the check engine light.

A little help? :{

Check to make sure the connection to the Data link conector is a good one... and also to the MAP sensor.

I will recheck all conections before I go home today. Does anyone know what these numbers are?

Codes.........

1693 is a companion code. It goes with all the others.



P-0237 is Map voltage too low. Check the connection.
