1. Inflate tires to the correct pressure: Check the sticker on your driver's side doorjamb for the recommended tire pressure for your vehicle. Inflate all four tires to this pressure using a reliable tire gauge.
2. Drive the vehicle: Drive the vehicle at a speed of at least 20 mph (32 km/h) for about 10-20 minutes. This allows the TPMS sensors to transmit their readings to the vehicle's computer.
3. Check the TPMS light: After driving, the TPMS warning light should turn off if the tire pressures are within the acceptable range. If the light remains on, there may be a problem with one or more sensors, a low tire, or a fault within the TPMS system itself.
Important Considerations:
* Persistent TPMS Light: If the light stays on after driving, don't ignore it. Check your tire pressures again. Low tire pressure is the most common cause. If pressures are correct, there could be a sensor malfunction or a more serious issue requiring professional diagnosis and repair. A scan tool capable of reading TPMS codes is needed for professional diagnostics.
* Sensor Issues: Sometimes a TPMS sensor can fail. If you suspect a faulty sensor, you will need to have it replaced by a qualified technician.
* Relearning Procedure Variations: While this is the typical procedure, there might be slight variations depending on the specific trim level of your van. Your owner's manual should provide the most accurate instructions for your vehicle. Always consult your owner's manual for the most accurate information.
If you've followed these steps and the light remains on, it's best to take your van to a mechanic or tire shop for diagnosis. They have the tools to properly diagnose and address TPMS issues.
