Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-P061A68

Condition

Note! This diagnostic trouble code (DTC) status is an event controlled diagnostic trouble code (DTC). An event controlled diagnostic trouble code (DTC) does not mean that there is a fault in the control module when it is active, but is designed as information.

Engine Control Module (ECM) monitors the torque in the engine by reading and interpreting signals from mass air flow sensor, electronic throttle unit and air pressure sensor in the inlet manifold.
The diagnostic trouble code (DTC) is stored if the measured torque exceeds the requested torque, based on the pedal position and the engine speed (RPM).
The diagnostic trouble code (DTC) can be diagnosed in specific driving conditions.

Substitute value
- The engine torque is limited by the throttle position (maximum permitted torque depends on accelerator pedal position).

Possible source
- Air leakage in the intake manifold (downstream of the mass air flow (MAF) sensor and electronic throttle unit).
- Damaged throttle unit.
- Damaged mass air flow (MAF) sensor.
- Damaged engine coolant temperature (ECT) sensor.
- Damaged flywheel sensor.
- Damaged air pressure sensor in the inlet manifold.
- Damaged turbocharger (TC) control valve.
- Damaged boost pressure control (BPC) valve pressure servo.
- Damaged VVT-unit.
- Damaged engine control module (ECM).

Fault symptom[s]
- None.
