Why does the TPMS light keep coming on after new tires?
A reset tells the system “these wheel speeds are normal” and any changes from that create a warning. If there is a problem with a sensor, ie the tire monkeys screwed one up, the system will assume a tire is soft the the light will stay on. Check all four tires, set them to 36 psi and reset the system.
How can I reset the TPMS light in my car?
Resetting the TPMS differs from car to car but there are some general techniques which are easy to execute and help in successfully recalibrating the monitoring system. Before you try to reset your TPMS light, you should always make sure that you have the right tire pressure in your vehicle. Use a tire pressure gauge to check the tire pressure.
Why is the TPMS light not always 100% accurate?
When a tire loses air pressure, the slower speed of the tire rotation is detected by the speed sensors of the Indirect TPMS. This causes the central computer to activate the TPMS light on the dashboard. Unfortunately, the TPMS is not always 100% accurate.
When do I need to change my tire pressure sensor?
Indirect tire pressure measuring systems or iTPMS sensors will trigger a warning light for any one or all of your tires. But, if you’re confident that your sensors are working properly and you know how to reset and recalibrate your sensors, then you may not have to change the TPMS sensors at the same time as your tires.
Why does the TPMS light come on after new tires?
Two weeks ago I bought 4 new tires form my 2008 Honda Fit Sport, then had an alignment. A week later, the “TPMS” light – not the (!) light indicating low pressure – came on and stayed on.
What to do if your TPMS warning light is still on?
If you’ve checked all your tires (including the spare) and the tire warning light is still illuminated, reset your tire pressure monitoring systems. Some models require the TPMS to be reset every time pressure is added. Instructions for how to reset your tire warning light vary from model to model.
Is it normal both TPMS sensors fail just after changing?
If you did the pressure reset correctly- Hold the button with the ignition on (not car on) until the tpms light blink 3 times, then leave ignition on for a few minutes before shutting it off- then it sounds like you did it right. Since that didn’t work, I would try swapping the two back tires to see if ID’s were out of place.
