1 3 1 1 1 1 1 1 Is the resistance greater than 10,000 ohms? DIAGNOSE the electronic engine control system. For additional information, refer toSection 303-14A Electronic Engine Controls Section 303-14B Electronic Engine Controls . No REPAIR the power supply circuit from the ECM to the accelerator pedal. CLEAR the DTC. TEST the system for normal PINPOINT TEST B : DTC P1122, P1123, P1215, P1216, P1344 TEST CONDITIONS DETAILS/RESULTS/ACTIONS B1: CHECK THE ACCELERATOR PEDAL DEMAND SENSOR OUTPUT Turn the ignition switch to the RUN position. Does the voltage vary between 0.3 volts and 5 volts? GO to B4 . . No GO to B2 . . B2: CARRY OUT AN ACCELERATOR PEDAL POSITION SENSOR COMPONENT CHECK Remove the accelerator pedal. For additional information, refer to Pedal . Measure the resistance between pin 1 and pin 6 of the accelerator pedal. Is the resistance between pin 1 and pin 6 between 546 and 1134 ohms, and between pin 2 and pin 3 between 975 and GO to B3 . . No INSTALL a new accelerator pedal. For additional information, refer to Pedal . CLEAR the DTC. TEST the system for normal operation. B3: CHECK THE ACCELERATOR PEDAL DEMAND SENSOR CIRCUIT FOR A SHORT TO GROUND Disconnect the ECM electrical connector EN16. Is the resistance greater than 10,000 ohms? GO to B4 . . No REPAIR the accelerator pedal demand sensor circuit from the ECM to the accelerator pedal. CLEAR the DTC. TEST the B4: CHECK THE ACCELERATOR PEDAL DEMAND SENSOR CIRCUIT FOR OPEN CIRCUIT Disconnect the ECM electrical connector EN16 and the accelerator pedal electrical connector PA1. Is the resistance less than 5 ohms? DIAGNOSE the electronic engine control system. For additional information, refer toSection 303-14A Electronic Engine Controls Section 303-14B Electronic Engine Controls . No REPAIR the accelerator pedal demand sensor circuit from the ECM to the accelerator pedal. CLEAR the DTC. TEST the PINPOINT TEST C : DTC P0121, P0122, P0123 TEST CONDITIONS DETAILS/RESULTS/ACTIONS C1: CHECK THE POWER SUPPLY TO THE THROTTLE POSITION SENSOR Turn the ignition switch the to the RUN position. Is the voltage less than 4.5 volts? GO to C2 . . No GO to C4 . . C2: CHECK THE THROTTLE POSITION SENSOR POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT Turn the ignition switch to the OFF position. Is the resistance less than 5 ohms? GO to C3 . . No REPAIR the throttle position sensor power supply circuit from the ECM to the throttle position sensor. CLEAR the C3: CHECK THE THROTTLE POSITION SENSOR POWER SUPPLY CIRCUIT FOR A SHORT TO GROUND Measure the resistance between EN13-4 and ground. Is the resistance greater than 10,000 ohms? DIAGNOSE the electronic engine control system. For additional information, refer toSection 303-14A Electronic Engine Controls Section 303-14B Electronic Engine Controls . No REPAIR the throttle position sensor power supply circuit from the ECM to the throttle position sensor. CLEAR the C4: CHECK THE THROTTLE POSITION SENSOR GROUND CIRCUIT |
