(1) DTC P0103 could be generated by foreign material blocking the MAF sensor screen causing an airflow restriction. If contaminants are found on the screen, check air filter installation in air cleaner tray and proper sealing of air cleaner and air tubes before proceeding.
(2) DTC is an automatic transmission related problem. If code is present, see appropriate ELECTRONIC CONTROLS article in AUTOMATIC TRANSMISSIONS section.
(3) DTC P1101 could be generated by a low charged vehicle battery or the garage exhaust ventilation system. Service the battery as necessary. Then remove ventilation system and properly vent to outside atmosphere.
(4) An EPC solenoid that is shorted to ground may result in a false vehicle speed sensor code (DTC P1500 or P1501). diagnose the EPC solenoid first, then recheck the VSS.
(5) Diagnostic trouble code is a 4WD related problem. If code is present, see appropriate ELECTRONIC CONTROLS article in AUTOMATIC TRANSMISSIONS section.
(6) 3.0L and 4.0L models have been built without a PSP switch. Disregard servicing DTCS P1650 or P1651.
