ground.
The sensor needs to be calibrated.
The ECM has failed. This is unlikely
703-8 Inching pedal position sensor signal abnormaal. The sensor has failed.
Intermittent connections or poor connections.
Mechanical devices are loose.
The ECM has failed. This is unlikely.
704-12 Transmission output speed sensor #2 bad
component.
Sensor failure
705-2 Headland auto shift switch-set gear switch
incorrect.
