u take them out and replace with real ones!!
Adjust the tire pressure to specs then take it for a drive. It will reset itself if everything is okay. If you have a faulty sensor the light will remain on.
normally the oil pressure switch is on the main block if you have a pressure guage or oil pressure light on the car if you disconnect the right switch the gauge will drop or the light will go out then you know that's the switch to change.
A tire with low air pressure will do that.
Low oil pressure is serious. The first thing to do is make sure that oil pressure is actually correct. If the pressure is ok, then the most common causes of an oil light staying on is either a loose connection at the oil pressure sensor or a faulty sensor itself.
The only way to reset the low tire pressure warning light is to remove or replace the low tire pressure sensor. When the sensor is not working properly the light will remain on.
TPMS - Tire Pressure Monitoring System. Check and set your tire pressure and drive the car. If the light remains on it could be a faulty sensor.
Likely a faulty coolant temperature sensor. Change the sensor.
Dirty/faulty dawn/dusk light sensor
Replace the faulty speed sensor and the light will reset itself after a short drive.
hi how do i reset tire pressure sensor light on
Could be a leaking oil pressure sensor. High pressure sensor is located on the housing above the oil filter and the low pressure sensor is located on the driver side of the engine block. If you see oil leaking around either sensor then this may be the problem. They are not difficult or expensive to replace as they simply bolt on and can be purchased at your local dealer for around $10. Your low pressure sensor could be faulty. There is a high pressure sensor and a low pressure sensor on your car. After driving, heat and movement of oil throughout the engine are the cause. However, the sensor could be faulty thus reading the low pressure being too low (like at low rpms and you have to gear down on a manual to get the rpms up and the light disappears). Shouldn't cost more than 80 bucks to have a mechanic replace it. Just make sure they know which is the LOW pressure sensor.
Yes, a faulty O2 sensor will cause the check engine light to come on. Many auto parts stores will plug in an ODBII code reader to your Expedition to get the "trouble code" that tells you which sensor (there are 4) is faulty, free of charge.
