GO to Pinpoint Test G258127t125.
G258127t125 : CHECK THE SENSOR GROUND AT THE FUEL TEMPERATURE 1. Disconnect the FT sensor electrical connector, IL09. 2. Reconnect the ECM electrical connector, PI01. 3. Measure the resistance between IL09, pin 02 (BG) and GROUND. Is the resistance greater than 5 ohms? -> Yes GO to Pinpoint Test G258127t126.
-> No GO to Pinpoint Test G258127t127.
G258127t126 : CHECK THE FUEL TEMPERATURE (FT) SENSOR GROUND 1. Disconnect the ECM electrical connector, PI01. 2. Measure the resistance between IL09, pin 02 (BG) and PI01, pin 19 (BG). Is the resistance greater than 5 ohms? -> Yes REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.
-> No GO to Pinpoint Test G258127t127.
G258127t127 : CHECK THE SENSOR GROUND AT THE FUEL RAIL PRESSURE 1. Disconnect the FRP sensor electrical connector, IL12. 2. Reconnect the ECM electrical connector, PI01. 3. Measure the resistance between IL12, pin 02 (BG) and GROUND. Is the resistance greater than 5 ohms? -> Yes GO to Pinpoint Test G258127t128.
