If the TIPS output becomes 0.2 V or less at times other than idling, TPS output is insufficient and diagnostic trouble code No. 12 is output. If the TIPS output and the target value inside the TCM do not match even after compensation is carried out while the engine is idling, the TPS sensor is defective and diagnostic trouble code No. 13 is output. If the TPS voltage becomes 0.2 V or less or 1.2 V or more while the engine is idling, the TPS adjustment is defective and diagnostic trouble code No. 14 is output.
