Diagnostic trouble code (DTC) information

Condition

Fig 1: Identifying Atmospheric Pressure Sensor

Courtesy of VOLVO CARS OF NORTH AMERICA.

Diagnostic trouble code (DTC) ECM-0A is stored If the atmospheric pressure sensor circuit is short-circuited to ground or voltage or if there is an open-circuit in the circuit.

Substitute Value

90 kPa (approximately 1000 meters above sea-level)
No leak diagnostic.

Possible Source

Signal too high:

Short-circuit to supply voltage in the signal cable
Faulty atmospheric pressure sensor.

Signal too low:

Short-circuit to ground in signal cable
Open-circuit in the signal cable
Faulty atmospheric pressure sensor.

Fault symptom[s]

Malfunction indicator lamp (MIL) lit.
