Description:

This error code is logged when the second 5-volt sensor supply circuit within the ECU provides a voltage lower than required, indicating a potential short circuit to ground. This can lead to insufficient sensor operation and affect the overall functionality of vehicle monitoring systems.

Reaction:

To safeguard the system, the ECU may limit operations or adjust settings based on the potentially unreliable or absent sensor data resulting from the low voltage condition.

Recommendations:

• Inspect and Test Circuit: Look for shorts to ground within the circuit. Use a multimeter to assess voltage levels to confirm the diagnosis.
• Resolve Wiring or Component Issues: Replace or repair any components or wiring that contribute to the low voltage condition.
• Reset ECU and System Calibration: After repairs are complete, reset the ECU to ensure all systems recalibrate for the corrected voltage levels. Test thoroughly to confirm functionality.
• Monitor System Stability: Continuously monitor the affected systems to ensure stable operation post-repair.

Note:

Maintaining the integrity of the electrical supply to sensors is critical for precise engine and vehicle monitoring. Immediate and thorough resolution of voltage issues is crucial to prevent broader system impacts.
