Corvette V8-5.7L VIN G (1997)
Intake Air Temperature Sensor: Testing and Inspection
The scan tool displays temperature of the air entering the engine, which should read close to ambient air temperature when engine is cold. The
temperature should rise as underhood temperature increases. If the engine has not been run for several hours (overnight) the IAT sensor temperature
and engine coolant temperature should read close to each other. If the PCM detects a malfunction in the IAT sensor circuit, the following DTCs will
set:
^
DTC P0112 circuit low.
^
DTC P0113 circuit high.
^
DTC P0111 circuit intermittent high.
^
DTC P1112 circuit intermittent low.
