DTC ECM-1300

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.

Substitute value
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 (MAF) sensor
- short-circuit to ground in signal cable
- open-circuit in signal cable
- faulty mass air flow (MAF) sensor.

Fault symptom[s]
None.
