I was driving along today and the CEL came on and it gave code P1120, which translates to Throttle Position Sensor out of range, and P1121 which means Throttle Position Sensor Inconsistent with Mass Air Flow Sensor. I reset them and it went away for a while but its back now and only P1120 has returned.Any recommendations at what needs to be done about this, ex tps replacement... Also the transmission hasn't been downshifting when you go from drive to 2nd, without giving it some gas, fluid is full, clean, not burnt and is not brown at all. Any recommendations on either subject would be great.
