Ford P0243 OBD-II Trouble Code Definition:
P0243 Turbo/Super Charger Wastegate Solenoid A
P0243 Ford OBD-II Trouble CodeDescription:
OBD Trouble Code P0243
Turbo/Super Charger Wastegate Solenoid “A”
What does the code mean? OBD-ii Code P0243 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 P0243
– 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 P0243
– 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
– 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
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.
