Combustion Engine Producing Insufficient Torque
The engine torque measured (or modelled from intake/exhaust signals) is below the calibrated set point for the commanded throttle position. Causes range from low compression, intake leak, fuel pressure issue, ignition fault, to high mechanical drag.
Affected components
- Powertrain control module
- Fuel injector
- Ignition coil
Common causes
- High likelihood: Low compression on one or more cylinders
- Medium likelihood: Fuel pressure low
- Medium likelihood: Intake leak
Diagnostic notes
- The malfunction indicator lamp may illuminate
- This code can affect emissions
- Reduced-power or limp mode may occur
