4-102 Powertrain DTC Charts and Descriptions
Diagnostic Trouble Code (DTC) Charts and Descriptions
P103A - Fuel Injector Heater Control Module Monitor Circuit (Continued)
All GO to Pinpoint Test AB.
P103B - Fuel Injector Heater Control Module Performance
Description: This DTC sets when an error occurs in the fuel injector heater control module.
Possible Causes: • Damaged fuel injector heater control module
Diagnostic Aids:
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test AB.
P1060 - Excessive Camshaft Chain Wear
Description:
Possible Causes:
Diagnostic Aids: Refer to the Workshop Manual Section 303-14, Electronic Engine Controls.
Application Key On Engine Off Key On Engine Running Continuous Memory
All Refer to the Description, Possible Causes and Diagnostic Aids for the DTC.
P1061 - Excessive Camshaft Chain Wear - Forced Limited Engine Speed
Description:
Possible Causes:
Diagnostic Aids: Refer to the Workshop Manual Section 303-14, Electronic Engine Controls.
Application Key On Engine Off Key On Engine Running Continuous Memory
All Refer to the Description, Possible Causes and Diagnostic Aids for the DTC.
P1100 - Mass Air Flow (MAF) Sensor Circuit Intermittent
Description: This DTC sets when the PCM has detected a sudden input change in the MAF sensor circuit through the
comprehensive component monitor (CCM). If during the last 40 warm-up cycles in ignition ON, engine running, the PCM detects an input change beyond the minimum or maximum calibrated limit, a continuous memory DTC is stored.
Possible Causes: • MAF circuit intermittent open
• MAF circuit intermittent short to voltage
• MAF circuit intermittent short to ground
• Damaged MAF sensor
• Damaged harness connector
• Damaged harness
Diagnostic Aids: While accessing the MAF PID on the scan tool, lightly tap on the MAF sensor or wiggle the MAF sensor
connector and harness. If the MAF PID suddenly changes, an intermittent fault is indicated.
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test DC.
P1101 - Mass Air Flow (MAF) Sensor Out Of Self-Test Range
Description: This DTC sets when during ignition ON, engine OFF, the MAF sensor output signal is greater than a calibrated
limit or during ignition ON, engine running, the MAF output signal is not within the calibrated range.
Possible Causes: • Low battery charge
• MAF sensor partially connected
• MAF sensor contamination
• Damaged MAF sensor
• Intake air leaks
