PINPOINT TEST HG : POSITIVE CRANKCASE VENTILATION (PCV) SYSTEMNormal Operation and Fault Conditions
Refer to the DTC Fault Trigger Conditions.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| PCM P04DB:00 | Crankcase Ventilation System Disconnected: No Sub Type Information | Sets when PCM detects the crankcase pressure sensor is disconnected. Verify the integrity of the PCV system. |
| PCM P051A:00 | Crankcase Pressure Sensor "A" Circuit: No Sub Type Information | Sets when PCM detects the crankcase pressure sensor voltage is greater than or less than a calibrated value. |
| PCM P051B:00 | Crankcase Pressure Sensor "A" Circuit Range/Performance: No Sub Type Information | Sets when PCM detects the crankcase pressure sensor is greater than or less than an expected value for the current operating conditions. |
| PCM P051C:00 | Crankcase Pressure Sensor "A" Circuit Low: No Sub Type Information | Sets when PCM detects the crankcase pressure sensor voltage is less than 1 V. |
| PCM P051D:00 | Crankcase Pressure Sensor "A" Circuit High: No Sub Type Information | Sets when PCM detects the crankcase pressure sensor voltage is greater than 4.9 V. |
| PCM P051E:00 | Crankcase Pressure Sensor "A" Circuit Intermittent/Erratic: No Sub Type Information | Sets when PCM detects the crankcase pressure sensor voltage is intermittently above the maximum value or intermittently below the minimum value for a calibrated threshold . |
| PCM P2282:00 | Air Leak Between Throttle Body and Intake Valve: No Sub Type Information | Sets when PCM detects an air leak that exceeds a calibrated limit for greater than 5 seconds. If the airflow entering the engine exceeds the airflow through the throttle, a leak is detected and this diagnostic fails. Verify the integrity of the PCV system. Refer to Positive Crankcase Ventilation (PCV) System for aditional information. |
| PCM U060E:00 | Lost Communication With Crankcase Pressure Sensor: No Sub Type Information | Sets when PCM no longer receives a signal from the crankcase pressure sensor. |
