At what pressure does tire light come on?

The TPMS alerts drivers when a vehicle’s tire reaches 25 percent below the recommended pressure. As an example, if your tires should be filled to 32 pounds per square inch (psi), the TPMS dash light will come on when the tire reaches 24 psi. Tire pressure is important for safe driving.

What to do if your tire pressure sensor is not working?

Make sure all tires are properly inflated. Remember you are setting the sensors back to “zero” so all tires must be properly inflated otherwise the sensors will not be calibrated properly and their readings will be incorrect. Check the battery. If your car uses a battery to power the sensor, be sure that it is not dead.

GM’s tire pressure monitor employs a sensor inside each tire’s valve stem. Reset each tire sensor light when you change tires or your tire pressure gets too low, causing the “TPMS” light to come on.

Are there tire pressure sensors on a trailer?

If the trailer is not available, the trailer tire pressure sensors can be learned using the new EL-52641 Trailer Presence Simulator Tester (Fig. 7), which can simulate the presence of a trailer. The tool can be helpful when a customer would like the trailer tire pressure sensors learned without having the actual trailer at the dealership.

When to inflate the tyre pressure on a car?

It is recommended that you check and inflate your tyre pressure when the tyres are cold. Tyres are considered cold if they have been parked for at least 3 hours or have only been driven a short distance at slow to moderate speeds.

Over the last week I’ve found my right front tire pressure started reading ~5 PSI low on the DIC compared to the actual pressure in the tire when measured with a gauge. All tires on the car have 37 PSI when measured with a gauge. All TPMS pressures report 37 except the RF which shows 32 PSI. Pressure go up slightly as expected after a short drive.
