Background
The engine control module checks current flows in the fuel pressure solenoid drive circuit
when the solenoid is on and off.
Check Area
Battery voltage is not lower than 10 V.
Judgement Criteria
Solenoid coil surge voltage (system voltage + 2 V) is not detected when the fuel pressure
solenoid is turned on/off.
Probable cause
Fuel pressure solenoid failed
Open or shorted fuel pressure solenold circuit,
or loose connector
Engine control module failed
