![]() Front Timing Actuator Circuit

Circuit Description
The timing actuators are actuated by the electronic control module (ECM) to control fuel timing. Each timing actuator is connected to the ECM by a supply and a return wire. An electrical pulse is sent to the timing actuator from the ECM on the supply wire and returns to the ECM on the return wire. Each solenoid valve is normally closed, and it is
only opened by an electrical pulse from the ECM during metering.
Component Location
The front timing actuator is mounted on the fuel delivery housing. It is the second actuator from the front of the engine.
Shop Talk
The possible failure modes are short circuit to battery, low actuator resistance, or short circuit between supply and return wires.
