3 1 1 1 1 1 1 1 Measure the resistance between the relevant injector harness electrical connector (IJ1 to 6) pin 1 and EN16 pins as Injector 1 pin 1 (NW) and ECM pin 115. Is the resistance less than 5 ohms? GO to A5 . No REPAIR the circuit between the relevant injector harness electrical connector pin 1 and the ECM electrical connector. A5: CHECK THE INJECTOR GROUND CIRCUIT FOR SHORT CIRCUIT TO BATTERY Measure the voltage between the relevant injector harness electrical connector (IJ1 to 6) pin 1 and GROUND. 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 A6 . A6: CHECK THE INJECTOR GROUND CIRCUIT FOR SHORT CIRCUIT TO GROUND Measure the resistance between the relevant injector harness electrical connector (IJ1 to 6) pin 1 and GROUND. Is the resistance less than 10,000 ohms? REPAIR the short circuit. For additional information, refer to wiring diagrams. CLEAR the DTC. TEST the system for No INSTALL a new ECM. Electronic Engine Controls - 2.5L NA V6 - AJV6/3.0L NA V6 - AJ27, VIN Range: E96603->J28492 (303-14A Electronic Engine Controls - 2.0L NA V6 - AJV6/2.5L NA V6 - AJV6/3.0L NA V6 - AJ27, Diagnosis and Testing). PINPOINT TEST B : FUEL RAIL PRESSURE SENSOR. P0190, P0192, P0193 TEST CONDITIONS DETAILS/RESULTS/ACTIONS B1: CHECK THE FUEL RAIL PRESSURE SENSOR SUPPLY VOLTAGE Turn the ignition switch to the OFF position. Is the supply voltage between 4.5 and 5.5 volts? GO to B2 . No REPAIR the circuit between IJ007 pin 1, (YG) and ENS07. For additional information, refer to wiring diagrams. CLEAR Electronic Engine Controls - 2.5L NA V6 - AJV6/3.0L NA V6 - AJ27, VIN Range: E96603->J28492 (303-14A Electronic Engine Controls - 2.0L NA V6 - AJV6/2.5L NA V6 - AJV6/3.0L NA V6 - AJ27, Diagnosis and Testing). (The fault could be in any of the components or sensors in the 5 volt supply circuit, or the ECM) B2: CHECK THE FUEL RAIL PRESSURE SENSOR GROUND CIRCUIT FOR OPEN CIRCUIT Turn the ignition switch to the OFF position. Is the resistance greater than 10,000 ohms? REPAIR the circuit between IJ007 pin 2 (WG) and ground at IJS02. For additional information, refer to wiring No GO to B3 . B3: CHECK THE FUEL RAIL PRESSURE SENSOR SIGNAL CIRCUIT FOR OPEN CIRCUIT Disconnect the ECM electrical connector EN16. Is the resistance greater than 5 ohms? REPAIR the circuit between IJ007 pin 3 (WG) and EN016 pin 73 (WG). For additional information, refer to wiring No GO to B4 . B4: CHECK THE FUEL RAIL PRESSURE SENSOR SIGNAL CIRCUIT FOR SHORT TO GROUND Measure the resistance between the fuel rail pressure sensor electrical connector IJ007 pin 3 (W G) and GROUND. Is the resistance less than 10,000 ohms? REPAIR the circuit between IJ007 pin 3 (WG) and EN016 pin 73 (WG). For additional information, refer to wiring No GO to B5 . B5: CHECK THE FUEL RAIL PRESSURE SENSOR CIRCUIT RESISTANCE Disconnect the fuel rail pressure sensor electrical connector IJ007. Is the resistance between 10,000 and 12,000 ohms? GO to B6 . No Install a new fuel rail pressure sensor. |
