Ford P0250 OBD-II Trouble Code Definition:
P0250 Turbo/Super Charger Wastegate Solenoid B High
P0250 Ford OBD-II Trouble CodeDescription:
OBD Trouble Code P0250
Turbo/Super Charger Wastegate Solenoid “B” High
What does the code mean? OBD-ii Code P0250 definition:
The PCM monitors the supercharger (boost) bypass (SCB) solenoid circuit for an electrical failure. The test fails when the signal moves outside the minimum or maximum allowable calibrated parameters for a specified SCB solenoid duty cycle (100% or 0%) by PCM command.
The PCM monitors the supercharger (boost) bypass (SCB) solenoid circuit for an electrical failure. The test fails when the signal moves outside the minimum or maximum allowable calibrated parameters for a specified SCB solenoid duty cycle (100% or 0%) by PCM command.
Symptoms Sumptoms of OBD code P0250
– Engine Light ON (or Service Engine Soon Warning Light)
– Engine Light ON (or Service Engine Soon Warning Light)
Causes Causes of the OBD-II code P0250
– VPWR circuit open to SCB solenoid. – SCB solenoid circuit shorted to PWR GND or CHASSIS GND. – Damaged SCB solenoid. – SCB solenoid circuit open. – SCB solenoid circuit shorted to VPWR. – Damaged PCM
– VPWR circuit open to SCB solenoid. – SCB solenoid circuit shorted to PWR GND or CHASSIS GND. – Damaged SCB solenoid. – SCB solenoid circuit open. – SCB solenoid circuit shorted to VPWR. – Damaged PCM
Solutions Disconnect SCB solenoid. Connect test lamp to SCB solenoid harness connector. Cycle SCB driver in PCM by Output Test Mode. Test lamp cycle on and off – SCB solenoid is suspect. Test lamp always on – SCB signal short in harness or PCM. Test always off – SCB signal or VPWR open in harness or PCM.
