PTH 000091.16 – Throttle Sensor Data Valid but Above Normal Operating Range – Moderately Severe Level

PTH 000091.16 (PTH 91.16)

Code: 000091.16

Shortcode: 91.16

Description:

This fault code indicates that the hand throttle sensor input is above the normal operating range, at a moderately severe level. This could be due to a more pronounced sensor issue, wiring problems, or calibration errors.

Reaction:

When this error is detected, the equipment may experience more noticeable throttle response issues, potentially affecting engine performance. The system may limit throttle functionality to prevent further issues.

Recommendations:

Inspect Hand Throttle (P03) Without ECU:

  • Check the hand throttle for proper operation.
  • Ensure the throttle is not damaged and is correctly positioned.

Verify Wiring and Connections:

  • Inspect the wiring harness connected to the throttle sensor for any signs of damage, wear, or loose connections.
  • Repair or replace any damaged wiring.

Test Power Train Hydrostatic Control Unit (PTH):

  • Perform diagnostic tests on the control unit to identify any faults.
  • Verify all electrical connections to the control unit are secure and corrosion-free.

Update Control Software:

  • Ensure the control unit software is up-to-date with the latest fixes and improvements.

Consult Technical Support:

  • If the fault persists, contact technical support for further diagnostics and possible sensor replacement.

Monitor System Performance:

  • After implementing the corrections, monitor the throttle system to ensure normal operation and that the fault does not recur.

Note:

Regular maintenance and calibration of the throttle sensor and associated wiring can help avoid such faults. Consider environmental factors like extreme temperatures or moisture, which can affect sensor performance during troubleshooting.
