Product Details

This Denso tire pressure monitoring system sensor is engineered for Ram truck TPMS service where accurate tire pressure data and factory system behavior matter. The 550-2506 is a direct-fit OE manufactured sensor for Ram 1500, Ram 2500, and Ram 3500 models from 2018 through 2021, making it a practical choice for replacing a failed sensor during tire service or warning-light diagnosis.

Common Issues It Can Help Address

• TPMS warning light stays on after tire service
• Faulty or unresponsive tire pressure sensor readings
• Loss of factory TPMS functions after sensor failure
• Diagnostic trouble codes related to tire pressure monitoring
• Need for an OE-style replacement on Ram 1500, Ram 2500, or Ram 3500 trucks

Installation Notes

After installation, the vehicle may require a TPMS relearn procedure according to the manufacturer’s service process. Denso notes that some do-it-yourself installations still need a trusted repair shop to complete relearn programming. Verify sensor placement and follow the Ram TPMS relearn steps for the specific model year before returning the vehicle to service.
