E Short-RF Valve Spring Solenoid Circuit

Short-Right Front Valve Spring Solenoid Circuit

PINPOINT TEST E: SHORT-RIGHT FRONT VALVE SPRING SOLENOID CIRCUIT:

PINPOINT TEST E: SHORT-RIGHT FRONT VALVE SPRING SOLENOID CIRCUIT (Continued):

The Control Module has detected a short in the circuit used to activate right front solenoid valve. There are five possible causes of this short which are listed below:
1. Battery Positive Voltage (B+) power supply circuit is shorted to ground.
2. Vehicle wiring harness has B+ power supply and ground return circuit to the solenoid valve reversed.
3. Solenoid valve is inoperative.
4. Control Module is inoperative.
5. The right front solenoid valve has a diode in it. When current is applied in the reverse direction this diode will act like a short. Because all ohmmeters do not have the same positive and negative polarity the following test procedures are being used to locate the cause of the short.
