Diagnostic Trouble Code (DTC) Information

ECM-1300 MASS AIR FLOW (MAF) SENSOR
DIAGNOSTIC TROUBLE CODE (DTC) INFORMATION




Condition
Diagnostic Trouble Code (DTC) ECM- 1300 is stored if the control module registers that the sensor circuit has a short-circuit to ground/voltage or if there is an open-circuit in the circuit.

Condition
Determine the air mass from the manifold absolute pressure (MAP) sensor and the engine speed (RPM).

Possible source

Signal too high:
- short-circuit to supply voltage in the signal cable
- faulty mass air flow (MAP) sensor
- short-circuit to ground in signal cable
- open-circuit in signal cable
- faulty mass air flow (MAP) sensor.

Condition
None.
