43242 14 Mercury CABLE ASSEMBLY, Throttle (26.50 Inches)

Note: The following conditions must exist before any of the above codes will become active:
The ECM has been powered for at least 2 seconds.
There are no active 168-X diagnostic codes.The ECM will log the diagnostic code. If equipped, the warning light will come on.This procedure covers open circuit diagnostic codes and short circuit diagnostic codes that are associated with the following sensors that are connected to the ECM:
Coolant temperature sensor
Intake manifold air temperature sensor
Fuel temperature sensor
Air inlet temperature sensor
Exhaust Gas Recirculation (EGR) pre-cooler temperature sensor
EGR post-cooler temperature sensorThe following background information is related to this procedure:The temperature sensors have two terminals. The signal line is connected to each sensor connector terminal 1. Terminal 2 is the return line. The signal voltage from terminal 1 of each sensor is supplied to the appropriate terminal in the ECM.Pull-up VoltageThe ECM continuously outputs a pull-up voltage on the circuit for the sensor signal wire. The ECM uses this pull-up voltage to detect an open in the signal circuit. When the ECM detects a voltage above a threshold on a signal circuit, an open circuit diagnostic code (XXX-3) is communicated to the engine ECM.If the sensor is disconnected, pull-up voltage at the connector indicates that the wires are not open or shorted to ground. If the sensor is disconnected, the absence of pull-up voltage indicates an open in the signal wire or a short to ground. If the sensor is disconnected and the voltage is different from pull-up voltage, the signal wire is shorted to another wire in the harness.
