What is TPMS?

The TPMS (Tire Pressure Monitoring System) is designed to measure air pressure and alert the driver when the pressure in one or more of the tires is below 25% of the manufacturer’s recommended pressure. There are two types of systems, direct and indirect. The far more...

How do you distinguish indirect TPMS from direct TPMS?

Direct TPMS uses direct tire pressure sensors on each wheel to measure tire pressure while indirect TPMS does not use sensors. Indirect TPMS frequently use the anti-lock brake system (ABS) speed sensors to calculate pressure.

How to ensure the vehicle has direct TPMS sensors?

Consult your Autel tool. Select the vehicle Make, Model and Year. The tool will note if the vehicle’s tire pressure monitoring system is an Indirect (no TPMS sensors) system. Direct TPMS sensors are fitted with either rubber or metal valve stems.

What does the TPMS dashboard light/warning indicate?

A TPMS warning light might display if: 1. The tire pressure on one or more tires is too high or too low. A variation of 25% from the recommended air pressure will cause a malfunction light. 2. One or more of the TPMS sensors may be broken or sensor batteries may be...

Why does my workshop need a TPMS tool?

What is the difference between high-line and low-line TPMS?

High Line: vehicles with high line systems display the location of the specific under-inflated tire as well as the tire pressure for all tires. Low Line: vehicles with low line systems will not indicate the location of the under-inflated wheel tire, and usually only...

How can I locate and solve TPMS issues?

To locate and solve TPMS issues, you need to complete the following steps: 1. Use an Autel tool to activate sensors, read accompanying tire and sensor information and scan for trouble codes 2. Depending on the detected TPMS code, repair or replace the damaged part/s....

Why does “NA” display after I activate sensors?

What are some facts about tire pressure?

1. The tire pressure will vary with temperature by about 1 PSI (0.07 bar) for every 12°F (7°C). This means that when the outside temperature decreases, the tire pressure will decrease. Tire pressure should always be set based on cold inflation tire pressure. 2. A tire...

Why can’t I activate the TPMS sensors?

Ensure your tool has the latest software. Ensure that the vehicle uses Direct TPMS. Make sure you have selected the right model year If more than one frequency type is listed for the vehicle, try both listings. The sensor may be damaged or its battery dead. In either...

Why is the TPMS light lit on the dash of my 2005 vehicle?
