DTC P0112: Intake Air Temperature Sensor Circuit Low
S4RS0A1104019
Wiring Diagram
8 Ground circuit check
1) Connect connectors to ECM.
2) Check for proper connection of MAF and IAT sensor
connector at “ORN” wire terminal.
3) Measure resistance between “ORN” wire terminal of
MAF and IAT sensor connector and vehicle body ground
with ignition switch turned OFF.
Is resistance below 5
:
?
Go to Step 10. Go to Step 9.
9 Ground circuit check
1) Remove ECM from its bracket with ECM connectors
connected.
2) Measure resistance between “C37-55” terminal of ECM
connector and vehicle body ground.
Is resistance below 3
:
?
“ORN” wire is open or
high resistance circuit.
Poor “C37-55”
connection. Faulty ECM ground
circuit.
If circuit is OK,
substitute a known-
good ECM and recheck.
10 IAT sensor check
1) Check IAT sensor according to “Mass Air Flow (MAF)
and Intake Air Temperature (IAT) Sensor Inspection: in
Section 1C”.
Is it in good condition?
Substitute a known-
good ECM and recheck. Replace MAF and IAT
sensor.
