1 1 1 1 1 1 1 1 Is the voltage greater than 1 volt? REPAIR the short circuit. For additional information, refer to the wiring diagrams. CLEAR the DTCs. TEST the system No INSTALL a new MAF sensor. Mass Air Flow (MAF) Sensor (303-14A Electronic Engine Controls - 2.0L NA V6 - AJV6/2.5L NA V6 - AJV6/3.0L NA V6 - AJ27, Removal and Installation). 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). PINPOINT TEST O : DTC P0051, P0052. LEFT-HAND BANK H02S HEATER TEST CONDITIONS DETAILS/RESULTS/ACTIONS O1: CHECK THE POWER SUPPLY CIRCUIT TO THE LEFT-HAND BANK HO2S HEATER Turn the ignition switch to the ON position. Is the voltage less than 10 volts? GO to O4 . No GO to O2 . O2: CHECK THE GROUND CIRCUIT TO THE LEFT-HAND BANK HO2S HEATER Turn the ignition switch to the OFF position. Is the resistance of each wire less than 5 ohms? GO to O3 . No REPAIR the circuit. For additional information, refer to the wiring diagrams. CLEAR the DTCs. TEST the system for O3: CHECK THE LEFT-HAND BANK HO2S CIRCUIT FOR SHORT TO GROUND Measure the resistance between the HO2S electrical connector EN32 pin 1 (GO) and GROUND. Is the resistance less than 10,000 ohms? REPAIR the short to ground. For additional information, refer to the wiring diagrams. CLEAR the DTCs. TEST the No INSTALL a new left-hand bank HO2S. For additional information, Heated Oxygen Sensor (HO2S) LH (303-14A Electronic Engine Controls - 2.0L NA V6 - AJV6/2.5L NA V6 - AJV6/3.0L NA V6 - AJ27, Removal and Installation). 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). O4: CHECK FUSE 42 OF THE ENGINE COMPARTMENT FUSE BOX Check the fuse. Is the fuse OK? GO to O6 . No GO to O5 . O5: CHECK FUSE 42 OF THE ENGINE COMPARTMENT FUSE BOX FOR A SHORT TO GROUND Measure the resistance between electrical connector JB34 pin 105 of the engine compartment fuse box and GROUND. Is the resistance less than 10,000 ohms? REPAIR short to ground between the engine compartment fuse box and the left-hand bank HO2S. For additional No INSTALL a new fuse. Check the circuit for cause of fuse failure. CLEAR the DTC. TEST the system for normal O6: CHECK THE POWER SUPPLY TO FUSE 42 IN THE ENGINE COMPARTMENT FUSE BOX Measure the voltage between fuse 42, electrical connector JB34 pin 105 and GROUND. Is the voltage less than 10 volts? Repair the circuit from the ECM control relay to the engine compartment fuse box. For additional information, refer to No Repair the circuit between the engine compartment fuse box and the HO2S. For additional information, refer to wiring PINPOINT TEST P : DTC P1606. ECM RELAY. TEST CONDITIONS DETAILS/RESULTS/ACTIONS P1: CHECK THE ECM CONTROL RELAY Turn the ignition switch to the ON position. Does the ECM relay make an audible click? GO to P2 . No GO to P6 . P2: CHECK FOR POWER SUPPLY FROM THE ECM CONTROL RELAY Measure the voltage between the ECM control relay JB34 pin 131 and GROUND. |
