Fixed CEL, finally have codes???HELP???

[SWM]

Pulled the dash, fixed CEL now I have codes.(94ATX frontal and upper 60K,batt.,alt, IAB,all battery cables,fuel pump, suspension, etc...)Here they are..(KOEO)327,214,(KOER)327,411,536,538,632. I've been chasing many problems but it's time to find the electrical problem! Many thanks in advance.

327 - DPFE output below self test minimum. Either the DPFE is unplugged, it's output is shorted to ground, or the sensor has failed.

214 - Issue with CID signal

411 - Idle speed fault

536 - Brake pedal not pressed or detected

538 - same for goosing the throttle

632 - same for the TCS

Sorry I should have given more info., I've been chasing what I think is a wiring harness problem. I've checked all my connections and the cam sensor(Wells) is only a few months old. I just finished a suspension swap but the car has taken a beating for a long time and I'm thinking that I broke a wire? I read that there are splices somewhere in the main harness, is there a way to test this? The 327 code seems like an electrical code along with the 214 and a 212 I got this morning so the combo of these points to wiring problem?maybe? Car won't start 2 times in a row but always starts the first time. I do have tach but bad cam sensor symtoms.Thanks. 94 ATX 127K

Still hoping for some help! I've searched way to many threads on the individual codes but I'm thinking they might be all related(212,214,327). Many thanks! 94 ATX

You can check for the 5V ref signal at the DPFE sensor (BR/W wire). Output is the GY/R wire. It must be above 0.2V to pass the self test.

The 212 and 214 codes may be related to a wiring or grounding fault at the iggnition module (DIS). Make certain all four mounting screws are tight (clean metal), that both hold down bots for the crossover tube are tight (again, clean metal), and that the grounding strap between the head at the #1 cylinder to the firewall is installed and tight (again, clean metal).
