Test Description

Number(s) below refer to the step number(s) on the Diagnostic Chart :

  1. 2. Verifies that the fault is present.
  2. 3. If DTC P0112 can be repeated only by duplicating the Failure Records condition, refer to the INTAKE AIR TEMPERATURE SENSOR CHART  table. The table may be used to test the IAT sensor at various temperatures to evaluate the possibility of a "shifted" sensor that may be stored above or below a certain temperature. If this is the case, replace the IAT sensor. If the IAT sensor appears to be OK, the fault is intermittent; refer to Diagnostic Aids.
