What Does “TP_B” Mean in OBD2?

“TP_B” is not a standard OBD2 diagnostic trouble code. Unlike generic codes (starting with “P0”) or manufacturer-specific codes (starting with “P1”), “TP_B” is not a recognized identifier for a specific vehicle fault.

The appearance of “TP_B” on your OBD2 scanner likely stems from one of the following scenarios:

• Scanner Misinterpretation: Some basic or outdated OBD2 scanners may misinterpret or incorrectly display certain data streams or commands, leading to the appearance of “TP_B.”
• Proprietary Software: Certain advanced scanners or software suites utilize their own terminology and abbreviations. “TP_B” might represent a specific parameter or function within that particular system. Always refer to the user manual of your scanner or software for clarification.
• Communication Error: A “TP_B” display could indicate a communication error between the scanner and your vehicle’s onboard computer. This might be due to a faulty OBD2 cable, incompatible scanner, or issues with the vehicle’s OBD2 port.

Troubleshooting “TP_B” on Your OBD2 Scanner

If you encounter “TP_B” on your OBD2 scanner, here’s a step-by-step approach to troubleshoot the issue:

1. Consult Your Scanner Manual: The most crucial step is to refer to your scanner’s user manual. Look for any mention of “TP_B” or similar abbreviations to understand its meaning within that specific device.
2. Check for Updates: Ensure your OBD2 scanner and its accompanying software (if applicable) are up-to-date. Manufacturers frequently release updates that improve compatibility and fix potential issues.
3. Inspect Your OBD2 Cable and Port: Examine your OBD2 cable for any visible damage, such as frayed wires or bent pins. Also, check the vehicle’s OBD2 port for dirt, debris, or bent pins that could hinder a secure connection.
4. Try a Different OBD2 Scanner: If possible, connect a different OBD2 scanner (ideally from a reputable brand) to your vehicle. This will help determine whether the issue lies with your scanner or the vehicle itself.
