Diagnostic Trouble Code (DTC) Information

ECM-P010800 Manifold Absolute Pressure/BARO Sensor High Input

Condition







The engine control module (ECM) measures the air pressure in the intake manifold using an air pressure sensor.

The diagnostic trouble code (DTC) is stored if the Engine Control Module (ECM) detects that the signal from the manifold absolute pressure (MAP) sensor in the intake manifold is too high.

The diagnostic trouble code can be diagnosed when the ignition is on.

Substitute Value
- The signal from the air pressure sensor in the intake manifold is set to a constant.
- Load/airflow calculations are carried out regardless of the signal from the air pressure sensor.

Possible Source
- The signal cable is short-circuited to voltage.
- Open-circuit in the signal cable.
- Damaged air pressure sensor in the intake manifold.

Fault Symptom[s]
- Malfunction indicator lamp (MIL) lit.
