Have the below codes and read outs. I have replaced the Throttle body - no change. P0121 says Accel pedal potentiometer. P1121 says Throttle position sensor 1. P1122 says Throttle potentiometer 2. From what I have read it could be the throttle pedal potentiometer failed or DME failed?? Possibly earth to DME from MAF?? One is a PITA but cheap to replace - the other, well extremely expensive the MAF is just a guess. Anyone else had similar? Any advice? Thanks.
