The Engine Control Module (ECM) detects the following conditions:
•The signal voltage from the atmospheric pressure sensor is greater than 4.9 VDC for more than 30 seconds.
•The ECM has been powered for at least two seconds.
Probable Causes:
1) ECM Connection/Harness
2) Crankcase breather plugged
3) Pressure sensor
4) Pressure sensor harness
5) ECM Failure
