Description:

This fault code arises when the voltage supplied to sensors is found to be above the normal operating range, specifically exceeding 5.2 volts. Such a condition may indicate an issue with the vehicle’s voltage regulator or electrical system, which can result in erratic sensor readings and potential sensor damage over time.

Reaction:

The control unit restricts certain functionalities to prevent damage or erroneous operation of sensors due to the high voltage.

Recommendations:

• Inspect Voltage Regulator: Check the voltage regulator’s functionality to ensure it maintains appropriate voltage levels within the sensor supply circuit.
• Examine Electrical Connections: Look for any signs of poor connections, damaged wires, or corrosion that might affect voltage levels. Repair or replace as needed.
• Monitor and Adjust System Voltage: Use a multimeter to monitor the voltage levels being supplied to the sensors. Make necessary adjustments or replacements to stabilize voltage supply.
• Test Sensor Functionality: After addressing voltage issues, test the sensors to confirm they are operating correctly without being affected by previous over-voltage conditions.
• System Calibration and Reset: Calibrate the sensors and reset the system to ensure all settings are back to normal operational standards.

Note:

Regular maintenance of the electrical system and routine checks of voltage levels are crucial to prevent high-voltage conditions and ensure sensor longevity and accuracy.
