New Holland 3053 – Engine: Vehicle Speed Sensing (Tacho) - PWM Frequency Too High

The system has detected that the Pulse Width Modulation (PWM) frequency from the vehicle speed sensing (tacho) is higher than the expected range. This may affect the accurate measurement of vehicle speed.

1. 1

   The vehicle speed sensing (tacho) signal

2. 2

   The wiring or connections to the vehicle speed sensing (tacho)

1. 1

   Inspect

   Inspect the vehicle speed sensing (tacho) for physical damage or wear.

2. 2

   Test

   Test the vehicle speed sensing (tacho) signal using a diagnostic tool to confirm the PWM frequency.

3. 3

   Check

   Check the wiring and connections to the vehicle speed sensing (tacho) for any loose, damaged, or corroded components.
