* With the engine idling and the transmission in the Park or Neutral position, observe the manifold absolute pressure (MAP) sensor parameter.
The MAP sensor parameter should be between 19-42 kPa.
瀚慠efer to DTC P0106 (See: P Code Charts/P0106) if the MAP sensor parameter is not between 19-42 kPa.
* With the engine idling, observe the mass air flow (MAF) sensor parameter. The MAF sensor parameter should be within 2-6 g/s at idle.
瀚慠efer to DTC P0101 or P1101 (See: P Code Charts/P0101) or DTC P0102 or P0103 (See: P Code Charts/P0102) if the MAF sensor
parameter is not within 2-6 g/s at idle.
