Description:

This error code is generated when the ECU control software detects an open circuit to the engine speed sensor. A replacement value is transmitted, generating this diagnostic trouble code in the PTF control software. This fault also generates a diagnostic trouble code in the ECU control software, which takes priority.

Reaction:

When this code is detected, the control software may exhibit limited or no functionality.

Recommendations:

• Inspect Engine Speed Sensor Circuit:
  • Check for an open circuit in the wiring to the engine speed sensor.
  • Repair or replace any damaged or disconnected wires.
• Test the Sensor:
  • Verify the functionality of the engine speed sensor using diagnostic tools.
  • Replace the sensor if it is found to be faulty.
• Check Connectors:
  • Ensure that all connectors are properly seated and free of corrosion.
  • Clean or replace connectors as needed.

Note:

Regular inspection and maintenance of the engine speed sensor and its circuit can prevent open circuit issues and ensure reliable operation.
