– Engine Light ON (or Service Engine Soon Warning Light) Possible Causes

Possible causes of 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 Possible 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.
