Manifold Pressure Control Valve
Unplug pressure control valve connector. Use an ohmmeter to check resistance between terminals No. 7 and 15. Resistance should be 85-95 ohms. Check resistance between terminals No. 8 and 10. Resistance should be 346-354 ohms. Check resistance between all terminals and ground. Resistance should be infinity. If readings are incorrect, replace manifold pressure control valve. See Figure.
