If NO MAP sensor or TP sensor DTCs are set, the engine has run more than 10 seconds, the engine IS warm, verify IAC is between 0 - 255 counts, the MAP is less than 55kPa OR the MAP is greater than 65kPa and the MAP is steady-- if all this is good, then the predicted throttle angle of the sensor does not match the actual throttle angle.
