Test Description
Number(s) below refer to the step number(s) on the
Diagnostic Chart:
2. Verifies that the fault is present.
3. If Diagnostic Trouble Code P0112 can be repeated
only by duplicating the Failure Records condition,
refer to the Temperature vs. Resistance Value 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.
