be tested using Digital Wrench®. If the ETC is faulty,
the entire assembly must be replaced.
Mounted to the intake plenum, the ETC acts as an
electronically controlled throttle body. The ETC controls
engine throttle operation to provide the proper air/fuel
ratio needed for engine operation at all RPM ranges. The
ETC controls engine RPM based off input provided by
the Pedal Position Sensor (PPS) and Electronic Control
Unit (ECU).
