What does this mean, tid$04 cid$09 high sensor voltage for switch time calculation?

The message you've provided, "tid$04 cid$09 high sensor voltage for switch time calculation," seems to be a diagnostic trouble code (DTC) or a communication message related to the OBD-II (On-Board Diagnostics) system in a 2003 Volkswagen Bora. This message indicates that there is an issue with a sensor's voltage related to the switch time calculation. However, the exact interpretation of this message might require more context and a detailed scan of the vehicle's diagnostic system.

In vehicles equipped with OBD-II systems, diagnostic trouble codes (DTCs) are generated to indicate specific issues detected within the vehicle's various systems. These codes are standardized and can help mechanics and technicians identify the root cause of problems.

In your case, "tid$04 cid$09" refers to a specific parameter or data identifier within the vehicle's diagnostic system. "High sensor voltage for switch time calculation" suggests that there's a sensor involved in some sort of calculation, and its voltage level is considered higher than expected.

To address this issue, follow these steps:

Retrieve Detailed Information: Use an OBD-II scanner or diagnostic tool to retrieve the full code and additional information associated with the "tid$04 cid$09" message. This will provide more context about which sensor and system are affected.

Inspect Sensors: Depending on the context, this issue could involve sensors related to various vehicle systems, such as emissions, transmission, or engine management. Inspect and test the sensors connected to the system identified by the code to ensure they are functioning correctly.

Check Wiring and Connections: Often, issues like high voltage readings can be caused by wiring problems, such as damaged wires, poor connections, or short circuits. Inspect the wiring and connectors associated with the sensor indicated by the code.

Sensor Replacement: If the sensor is indeed faulty and causing high voltage readings, it may need to be replaced. Ensure you use the appropriate replacement part recommended for your specific Volkswagen Bora model.

Clear Codes: After addressing the issue, clear the stored DTCs using the OBD-II scanner. This will reset the vehicle's error memory and allow you to monitor if the issue returns.

We should do a CAN scan; you can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon here is a video to show you how:
