Diagnose Tire Pressure Lights & Faulty Sensors
Your tire pressure monitoring system helps alert you when one or more tires are significantly underinflated. Many modern vehicles use battery-powered sensors mounted inside each wheel to measure tire pressure and transmit information to the vehicle.
A warning light may be caused by low tire pressure, seasonal temperature changes, a damaged sensor, a weak sensor battery, a leaking valve stem, incorrect sensor programming, or a system communication concern. Proper testing helps identify whether the tire or the monitoring system needs service.

What We Inspect & Service
Tire Pressure Sensors
Sensors are tested for pressure readings, signal strength, identification, battery condition, damage, and compatibility.
Valve Stems & Seals
Valve stems, valve cores, seals, retaining nuts, and service components are inspected for leakage, corrosion, and damage.
Vehicle Receiver
The vehicle's TPMS receiver, control module, stored fault codes, and sensor communication are evaluated when needed.
Solid TPMS Light vs. Flashing TPMS Light
Solid Warning Light
A solid warning commonly means one or more tires are underinflated and should be inspected and adjusted.
Flashing Warning Light
A flashing light may indicate the system cannot communicate with one or more sensors or has detected a TPMS malfunction.
Light Returns
If the warning returns after pressure correction, a tire leak, valve stem leak, sensor problem, or relearn issue may be present.
Direct vs. Indirect Tire Pressure Monitoring
Direct TPMS
Direct systems use pressure sensors mounted inside the wheels to transmit tire pressure information to the vehicle.
Indirect TPMS
Indirect systems use wheel-speed information to identify changes in tire rotation that may indicate low pressure.
System-Specific Service
Testing and reset procedures depend on the vehicle's monitoring system, sensor design, and manufacturer requirements.
New Sensors May Require Programming
Many replacement sensors must be programmed with the correct vehicle protocol and registered with the TPMS control system. Some vehicles relearn sensors automatically, while others require a scan tool, activation tool, driving procedure, or manufacturer-specific relearn.
TPMS Sensors Have Internal Batteries
Direct TPMS sensors contain sealed internal batteries that eventually lose power. Because the batteries are generally not replaceable separately, the sensor assembly may need replacement when battery strength becomes too low for reliable communication.
TPMS Service for Most Vehicle Types
What We Inspect, Program & Repair
Tire Pressure Check
We verify actual tire pressure against the vehicle manufacturer's recommended specification.
Sensor Signal Testing
Each sensor is checked for identification, signal strength, pressure data, temperature data, and battery condition.
Sensor Replacement
Failed, damaged, corroded, or non-communicating sensors can be replaced with compatible components.
Valve Stem Service
Valve cores, seals, retaining nuts, stems, and service kits are inspected and replaced when necessary.
Sensor Programming
Replacement sensors are programmed to match the correct vehicle protocol when required.
TPMS Relearn
The vehicle is guided through the proper relearn process so it can recognize sensor IDs and wheel positions.
System Code Scan
Stored TPMS fault codes and communication concerns are checked when the warning light flashes or does not reset.
Final Verification
We confirm pressure readings, sensor communication, warning light status, and proper system operation.
Our TPMS Diagnostic & Service Process
1. Tire Pressure Inspection
We inspect tire inflation, visible damage, tread condition, valve stems, and signs of leaks.
2. Sensor Activation
Each wheel sensor is activated and checked for signal, pressure data, battery condition, and communication.
3. System Diagnosis
If the warning light flashes or persists, we check for stored faults, programming issues, incompatible sensors, or receiver concerns.
4. Repair Recommendation
We explain whether the vehicle needs pressure correction, leak repair, valve service, sensor replacement, programming, or relearn.
5. Programming & Relearn
Approved replacement sensors are programmed and registered using the correct vehicle-specific procedure.
6. Final Check
Pressure readings, warning light status, sensor communication, and system operation are verified before completion.
Why the Tire Pressure Light May Stay On
Low Tire Pressure
Temperature changes, punctures, bead leaks, valve leaks, and normal air loss may cause pressure to fall below the warning threshold.
Failed Sensor
Internal battery failure, impact damage, corrosion, or moisture may prevent a sensor from transmitting reliable information.
Relearn or Programming Issue
Sensors may not be recognized after replacement, wheel changes, tire rotation, or incorrect programming.
