However, if the light remains on after proper inflation and driving, you may need to take these steps:
* Check tire pressure: Ensure all tires, including the spare, are inflated to the correct pressure listed on the sticker located on the driver's side doorjamb or in your owner's manual. Use a reliable tire gauge.
* Check for leaks: Inspect tires for any punctures or slow leaks.
* Drive the vehicle: Drive for 10-20 minutes at speeds above 20 mph. The TPMS should re-learn the new pressures.
* Try a relearn procedure (if necessary): Some Ford F-150 models may require a specific relearn procedure. This often involves cycling the ignition switch or using a scan tool. Consult your owner's manual for the specific procedure for your year and model. This procedure is usually not necessary unless there has been a TPMS sensor replacement or battery change.
* Use a scan tool: A professional-grade OBD-II scan tool can read TPMS sensor data and may be able to help diagnose or reset issues more accurately. A mechanic can also use a scan tool to check for TPMS problems.
* Check for sensor issues: If none of the above works, one or more of your TPMS sensors might be faulty. This requires professional diagnosis and likely sensor replacement.
Crucially, your owner's manual is the definitive guide. It will outline the precise steps for your vehicle's year and model, and may include specific troubleshooting information. Do not attempt any complex procedures without understanding the instructions thoroughly. If you're unsure, consult a qualified mechanic.
