Question
Why does TPMS trigger a warning after tire rotation?
Answer
Sensor IDs shift to new wheel positions, confusing systems that map IDs to specific corners.
Explain
Many TPMS ECUs store “corner-specific” sensor IDs (e.g., left-front = ID X). After rotation, the ECU still expects old IDs in original positions. A simple relearn (OBD or auto-drive) resolves this—CHEPQ tools can push new ID-to-corner mappings directly to the ECU, skipping 10+ minutes of test driving.
