. Test the operation of the cruise control switch. There is a condition where the cruise Multiplex (MUX) circuit shorts to battery voltage and then causes the Powertrain Control Module (PCM) to set this code. The cause of this is usually a shorted clock spring.

2. Test the voltage at all wires for the Throttle Position Sensor (TPS). The Orange wire should have 5 volts with the sensor connected. The Black/Blue wire should have 0 volts. The Orange/Blue wire should have 0.5 to 1.0 volt at idle and increase with throttle opening. The Orange/Blue wire should have 5 volts with the sensor disconnected

Check the signal from the Throttle Position Sensor at the Sensor with a DVOM on the signal wire. Then unplug the Clockspring and test the voltage at the Cruise Mux wire. 5 volt on the TPS signal wire & the cruise control MUX wire are shared in the PCM
