John Deere 000091.03 – CAB: Throttle Position Sensor Circuit Voltage High

The Cab Control Unit (CAB) has detected a voltage from the foot throttle sensor that is higher than the expected range. The foot throttle sensor converts the physical movement of the foot pedal into an electrical signal to regulate engine speed. A high voltage reading indicates a potential short circuit to power or a faulty sensor, which will negatively affect the proper operation of the machine's speed control.

1. 1

   Review stored codes using the machine's diagnostic interface to confirm if the code is active or stored and if any other related codes are present

2. 2

   Visually inspect the wiring harness and connectors between the foot throttle position sensor and the control unit for any signs of damage, corrosion, or loose connections

3. 3

   Perform basic electrical checks for continuity and ensure there are no shorts to power in the sensor wiring
