Multiple DTC. Where to start?


When driving, very seldom, I will get a CEL, throttle wont respond. The engine stays running at idle with no missing. A few seconds later, CEL goes away, and the throttle comes back. Everybodys happy again.

So, I pulled a couple codes today.

P0221 | Throttle switch B circuit performance | Failed pedal assembly

P0236 | Turbo boost sensor A circuit performance |Restricted inlet/exhaust/supply hose, missing hose

P0470 | Exhaust back pressure sensor circuit malfunction | Biased sensor, open signal return

P0603 | Internal control module KAM error | Open PCM pin, disconnect B+, faulty PCM

P1211 | ICP pressure above/below desired | IPR valve failed, stuck, or shorted to ground

P1705 | TR sensor out of self-test range | Operator error, circuit failure, faulty sensor, PCM

P0221 | Would explain the CEL and no Throttle.

P0236 | All Turbo hoses are intact and in good condition. ???

P0470 | Bad Sensor?

P0603 | Bad pin on PCM?

P01211 | ICP is Bad maybe?

P01705 | This would explain the terrible lope I had on startup for a while.

My scan tool wouldnt clear the codes so Ill have to wait till Monday before I can get my hands on something that can.

Thanks guys!
