The servomotor connector is located on the hot side of the engine near the valve cover. Heat cycles make the insulation brittle. Look for:
Check continuity between Pin 1 and chassis ground. Should be less than 1 ohm. 2aa8 dme variable intake system servomotor activation
Corroded connectors or broken wires in the harness can prevent the DME from successfully activating the motor. The servomotor connector is located on the hot
Measure resistance between Pin 2 and Pin 1. A healthy servomotor shows 5–15 ohms. An open loop (>1M ohm) indicates a dead motor. A short (<0.5 ohms) indicates a shorted motor. 0.5 ohms) indicates a shorted motor.
