1 1 1 1 1 1 1 Is the voltage greater than 1 volt? REPAIR the short circuit. For additional information, refer to wiring diagrams. CLEAR the DTC. TEST the system for No GO to Z5 . Z5: CHECK CONTINUITY OF THE APP SENSOR SIGNAL WIRE Turn the ignition switch to the OFF position. Is the resistance less than 5 ohms? GO to Z6 . No REPAIR the circuit between the APP sensor electrical connector PA1 pin 4 (R) and the ECM electrical connector EN16 Z6: CHECK CONTINUITY OF THE APP SENSOR POTENTIOMETER Measure the resistance between APP sensor electrical connector PA1 pins 4 and 6. Does the resistance vary as the pedal is operated? INSTALL a new ECM. Engine Control Module (ECM) (303-14A Electronic Engine Controls - 2.0L NA V6 - AJV6/2.5L NA V6 - AJV6/3.0L NA V6 - AJ27, Removal and Installation). No INSTALL a new accelerator pedal position sensor, Accelerator Pedal (310-02 Acceleration Control, Removal and Installation). CLEAR the DTC. TEST the system for normal operation. PINPOINT TEST AA : P2122, P2123. APP SENSOR ( TRACK 3) TEST CONDITIONS DETAILS/RESULTS/ACTIONS AA1: CHECK THE POWER SUPPLY CIRCUIT TO THE APP SENSOR. TRACK 3 Turn the ignition switch to the ON position. Is the voltage greater than 4 volts? GO to AA2 . No REPAIR the circuit between the APP sensor electrical connector PA1 pin 1 (Y) and the sensor 5 volt supply. CLEAR the (This circuit includes the ECM, EMS control relay, and pow er distribution fuse box. For additional information, refer to w iring diagrams. This supply is also AA2: CHECK THE GROUND CIRCUIT TO THE APP SENSOR Turn the ignition switch to the OFF position. Is the resistance less than 5 ohms? GO to AA5 . No REPAIR the circuit between the APP sensor electrical connector PA1 pin 3 (BG) and GROUND. CLEAR the DTC. TEST the (This circuit includes the ECM. For additional information, refer to w iring diagrams.) AA3: CHECK THE GROUND CIRCUIT TO THE APP SENSOR FOR CONTINUITY Disconnect the ECM electrical connector EN16. Is the resistance less than 5 ohms? GO to AA4 . No REPAIR the circuit. For additional information, refer to wiring diagrams. CLEAR the DTC. TEST the system for normal AA4: CHECK THE GROUND CIRCUIT TO THE APP SENSOR FOR SHORT TO BATTERY Connect the ECM electrical connector EN16. Is the voltage greater than 1 volt? REPAIR the short circuit. For additional information, refer to wiring diagrams. CLEAR the DTC. TEST the system for No GO to AA5 . AA5: CHECK CONTINUITY OF THE APP SENSOR SIGNAL WIRE Measure the resistance between APP sensor electrical connector PA1 pin 1 (Y) and the ECM electrical connector EN16 Is the resistance less than 5 ohms? GO to AA6 . No REPAIR the circuit between the APP sensor electrical connector PA1 pin 1 (Y) and the ECM electrical connector EN16 |
