Diagnostic Trouble Code (DTC) Charts and Descriptions
P100F - Wastegate Control Pressure/BARO Correlation
Description: This DTC sets when the difference between the wastegate vacuum sensor reading is greater than the
barometric pressure (BARO) sensor, manifold absolute pressure (MAP) sensor and the turbocharger boost pressure (TCBP) sensor readings by a calibrated threshold at key ON, engine OFF (KOEO), and the fault timer has exceeded the calibrated time threshold.
Possible Causes: • Contaminated or restricted wastegate vacuum sensor
• Restricted wastegate actuator control tube
• Restricted vent tube from the turbocharger wastegate regulating valve to the intake air tube
• Damaged wastegate vacuum sensor
Diagnostic Aids: The typical sensor difference threshold is 8.47 kPa (1.23 psi) and time threshold is 5 seconds.
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test HN.
P1011 - Wastegate Control Pressure Sensor Circuit Range/Performance
Description: This DTC sets when the wastegate vacuum sensor reading has exceeded the atmospheric pressure by greater
than a calibrated threshold and the fault timer has exceeded the calibrated time threshold.
Possible Causes: • Damaged wastegate vacuum sensor
Diagnostic Aids: The typical maximum threshold is 10.16 kPa (1.47 psi) and time threshold is 5 seconds.
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test HN.
P1012 - Wastegate Control Pressure Circuit Low
Description: This DTC sets when the wastegate vacuum sensor reading is less than a calibrated threshold and the fault timer
has exceeded the calibrated time threshold indicating a short to SIGRTN or ground.
Possible Causes: • WVS circuit short to ground
• Damaged wastegate vacuum sensor
Diagnostic Aids: The typical minimum threshold is 0.2V and time threshold is 5 seconds.
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test HN.
P1013 - Wastegate Control Pressure Circuit High
Description: This DTC sets when the wastegate vacuum sensor reading is greater than a calibrated threshold and the fault
timer has exceeded the calibrated time threshold indicating an open circuit or a short to voltage.
Possible Causes: • WVS circuit open
• WVS circuit short to voltage
• Damaged wastegate vacuum sensor
Diagnostic Aids: The typical maximum threshold is 4.93 V and time threshold is 5 seconds.
Application Key On Engine Off Key On Engine Running Continuous Memory
All GO to Pinpoint Test HN.
P1014 - Wastegate Control Pressure Circuit Intermittent/Erratic
Description: This DTC sets when the wastegate vacuum sensor reading is less than or greater than the minimum or
maximum calibrated thresholds and the fault counter has exceeded the calibrated count threshold indicating an intermittent open or short circuit.
Possible Causes: • WVS circuit intermittent open
• WVS circuit intermittent short to voltage
• WVS circuit intermittent short to ground
• Damaged wiring or harness connector
• Damaged wastegate vacuum sensor
Diagnostic Aids: The typical minimum and maximum threshold is 0.2 V and 4.93 V and the count threshold is 25.
