Toyota 4Runner tire pressure monitoring system light on despite proper tire inflation and sensor issues on Toyota 4Runner

Some Toyota 4Runner owners report experiencing issues with the tire pressure monitoring system (TPMS) light remaining on despite proper tire inflation. This can be caused by factors such as depleted batteries in the TPMS sensors, which may lead to inaccurate readings and trigger the warning light. Additionally, a malfunctioning TPMS receiver module can prevent the system from receiving signals from the sensors, resulting in a false warning. Owners may also encounter problems with damaged pressure sensors, which can send incorrect data to the TPMS, keeping the light illuminated. In some cases, resetting the TPMS system can help resolve the issue, and consulting the owner's manual may provide further troubleshooting guidance. If the light persists, seeking assistance from a dealer is advisable.
