Pinpoint Tests


PINPOINT TEST HG : POSITIVE CRANKCASE VENTILATION (PCV) SYSTEM

Normal 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.
