NOTE: Repair the short to ground between pin 2 of the intake air temperature sensor harness connector and pin 119 of the motor control module (MCM) 120 – pin connector. PROBABLE CAUSES:1. Intake manifold air temperature sensor failure.2. Intake manifold air temperature sensor harness/connector (Ping 2 of the intake air temperature harness connector and pin 119 of the 120 pin ECM connector).

DESCRIPTION:This fault code sets when the engine is in smoke mode control for an excessive amount of time due to inadequate clean airflow into the engine. MONITORED PARAMETER:Smoke mode operation. TYPICAL ENABLING CONDITIONS:General enabling conditions: engine is in smoke mode.Specific Enabling Conditions: See table below.1. Engine Coolant Outlet Temperature:– Min: 65°C (149°F)2. Barometric Pressure (mbar):– Min: 7553. Ambient Temperature:– Min: -8°C (18°F) MONITOR SEQUENCE:None EXECUTION FREQUENCY:Continuous when enabling conditions met. TYPICAL DURATION:13 seconds DASH LAMPS:1. MIL2. CEL ENGINE REACTION:Derate 25% VERIFICATION:Once engine is at standard operating temperature, operate engine on highway, coast for 30 seconds and then snap throttle and...

NOTE: Please see the step by step troubleshooting procedures for this specific code. PROBABLE CAUSES:1. Wiring between manifold pressure/temperature sensor and ECM connector.2. Intake manifold pressure/temperature sensor.

NOTE: The common powertrain controller (CPC) digital outputs have the same SPN as some motor control module (MCM) faults. The diagnostic service tool makes the distinction between the MCM and CPC when diagnosing a fault. NOTE: Vehicle power shutdown – indicates a short to power on the pin 02 circuit of the CPC #4 connector.
