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.
