DTC Detecting Condition and Trouble Area
8 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 5
Ω ?
“GRY/BLU” wire and/or
“ORN” wire is open
circuit or high resistance
circuit. Poor “C37-55”
connection.
Faulty ECM ground
circuit. If circuit is OK,
substitute a known-
good ECM and recheck.
9 IAT sensor for performance check
1) Check IAT sensor according to “MAF and IAT Sensor
Inspection in Section 1C”.
Is it in good condition?
Substitute a known-
good ECM and recheck.
Replace MAF and IAT
sensor.
