Diagnostic Trouble Code (DTC) Information

ECM-150A MASS AIR FLOW (MAF) SENSOR
DIAGNOSTIC TROUBLE CODE (DTC) INFORMATION




Condition
- driving with Engine Coolant Temperature (ECT) over 80°C (176°F) (warm engine)
- [lambda]-active control.
The control module compares values between intake manifold pressure (MAP) sensor and Mass Air Flow (MAF) pressure sensors in (g/rpm). Diagnostic Trouble Code (DTC) ECM-150A is stored if the control module registers that the deviation is too great.

Condition
None.

Possible source

Upper limit
- the intake manifold (MAP) pressure sensor displays more than the Mass Air Flow (MAF) sensor.

Lower limit
- The Mass Air Flow (MAF) sensor displays more than intake manifold (MAP) pressure.

Condition
None.
