Hello,
I have a 2009 Chevrolet Express 3500 Duramax 1GAHG356991100496. It has 2 seconds of throttle response from a dead take-off and then nothing. CEL, ABS light, and parking brake light are on. I had a friend with a scanner scan it and it has the following codes:
U0198-Lost communication with telematic control module (Symptom 00)
P20B9-Reductant heater A control circuit/open (Symptom 00)
P204C-Reductant pressure sensor circuit low (Symptom 00)
P20A0-Reductant purge control valve circuit/open (Symptom 00)
U010E-Lost communication with reductant control module (Symptom 00)
U029E-Lost communication with NOx sensor B (Symptom 00)
P208A-Reductant pump control circuit/open (Symptom 00)
P205D-Reductant tank temperature sensor circuit high (Symptom 00)
P0112-Intake air temperature circuit signal low (Symptom 00)
All fuses are good. It has throttle response in park. I cannot find any information on most of these codes online.
