DTC Fault Trigger Conditions
DTC |
Description |
Fault Trigger Condition |
PCM P0234:00 |
Turbocharger/Supercharger 'A' Overboost Condition: No Sub Type Information |
This DTC sets when the turbocharger system TCBP PID value is greater
than a calibrated threshold, or the turbocharger system TCBP PID value
is greater than the turbocharger boost pressure (TCBP) desired value for
a calibrated length of time.
Check tubing for restrictions, cracks and incorrect fitting
connections.
Check the turbocharger wastegate regulating valve solenoid for correct
operation.
|
PCM P0245:00 |
Turbocharger/Supercharger Wastegate Actuator 'A' Low: No Sub Type Information |
Sets when the PCM detects an open circuit or a short to ground from the TCWRVS circuit.
This DTC only sets when the solenoid valve is energized.
|
PCM P0246:00 |
Turbocharger/Supercharger Wastegate Actuator 'A' High: No Sub Type Information |
Sets when the PCM detects high voltage from the TCWRVS circuit.
This DTC only sets when the solenoid valve is energized.
|
PCM P0299:00 |
Turbocharger/Supercharger 'A' Underboost Condition: No Sub Type Information |
Sets when the PCM
detects the actual turbocharger boost pressure (TCBP) value is less
than the desired turbocharger boost pressure (TCBP) value by 27.6 kPa (4
psi) or more for 5 seconds, indicating an under boost condition.
Check tubing for restrictions, cracks and incorrect fitting connections.
Check the turbocharger wastegate regulating valve solenoid for correct operation.
