P0103 Mass air flow (MAF) sensor sensing circuit high voltage
MAF sensor to ECM sensing circuit; short circuit to MAF sensor to ECM ground circuit; open circuit MAF sensor failure
For MAF sensor tests, GO to Pinpoint Test G258127p1.
P0105 Manifold absolute pressure (MAP) sensor range/performance
Intake manifold air leak (loose or missing MAP sensor to ECM circuit(s) fault MAP sensor failure Throttle adaptation fault (check throttle position
Check air intake system. For further information, Intake Air Distribution and Filtering - VIN Range: G00442- >G45703 For MAP sensor circuit tests, GO to Pinpoint Test G258127p33. Throttle adaptation is automatic at key on.
P0106 BARO sensor circuit range/performance
BARO failure (internal ECM fault)
Contact dealer technical support for advice on possible ECM failure.
P0107 BARO sensor circuit, low voltage
BARO failure (internal ECM fault)
Contact dealer technical support for advice on possible ECM failure.
P0108 BARO circuit, high voltage
BARO failure (internal ECM fault)
Contact dealer technical support for advice on possible ECM failure.
P0111 Intake air temperature (IAT) sensor range/performance
Blocked air filter Air intake leak Engine breather leak IAT sensor to ECM wiring; open circuit or high IAT sensor to ECM sensing circuit; short circuit to IAT sensor failure
Check air filter element, air intake system for leaks. For further information, Intake Air Distribution and Filtering - VIN Range: G00442- >G45703 Check engine breather system. For further information, Engine Emission Control - VIN Range: G00442->G45703 For IAT sensor tests, GO to Pinpoint Test G258127p2.
