-> Yes REPAIR the short circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.
-> No GO to Pinpoint Test G258127t90.
G258127t90 : CHECK THE APP SENSOR SENSING CIRCUIT FOR SHORT TO 1. Turn the ignition switch to the OFF position. 2. Measure the resistance between CR14, pin 04 (R) and GROUND. Is the resistance less than 10,000 ohms? -> Yes REPAIR the short circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.
-> No GO to Pinpoint Test G258127t91.
G258127t91 : CHECK THE APP SENSOR SUPPLY VOLTAGE AT THE SENSOR 1. Reconnect the ECM electrical connector, PI01. 2. Turn the ignition switch to the ON position. 3. Measure the voltage between CR14, pin 05 (Y) and GROUND. Is the voltage less than 4 volts? -> Yes GO to Pinpoint Test G258127t92.
-> No INSTALL a new APP sensor. Accelerator Pedal (19.20.01) CLEAR the DTC. TEST the system for normal operation. G258127t92 : CHECK THE APP SENSOR SUPPLY VOLTAGE CIRCUIT FOR 1. Turn the ignition switch to the OFF position. 2. Disconnect the ECM electrical connector, PI01. 3. Measure the resistance between CR14, pin 05 (Y) and PI01, pin 13 (Y). Is the resistance greater than 5 ohms? -> Yes REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. CLEAR the |
