A tire-pressure monitoring system (TPMS) monitors the air pressure inside the pneumatic tires on vehicles. [1] A TPMS reports real-time tire-pressure information to the driver, using either a gauge, a pictogram display, or a simple low-pressure warning light. TPMS can be divided into two different types – direct (dTPMS) and indirect (iTPMS).
The air inside a tire condenses in colder weather, taking up less space and lowering tire pressure. The Consumer Reports website notes that tire pressure will drop 1 psi for every 10 degree drop ...

direct TPM sensor fitted in valve system, manufacturer VDO. In most current designs of direct TPMS, a small electronic assembly which is rugged enough to be mounted inside a tire, measures the pressure using a microelectromechanical system (MEMS) [1] pressure sensor and then transmits this and other information to one or more vehicle receivers.

Many modern cars now come with built-in tire pressure sensors that allow all four tire pressures to be read simultaneously from inside the car. Before 2005, most on-board tire-pressure monitoring systems (TPMS) used indirect pressure monitoring. The anti-lock brake sensors detect one tire rotating faster than the rest and indicate a low tire ...
You may hear a squeak or popping sound as the air pressure equalizes. Fluid in the Ear The most common cause of fluid in the ear is an infection, but it can also be caused by other medical conditions.
The oil pressure idiot light lights when engine oil pressure drops below a predetermined level. The light normally appears when the vehicle ignition is turned on, but the engine is not running, as it detects no oil pressure due to the oil pump not operating (the oil pump is powered off the crankshaft, so only operates when the engine is running ...
Cold inflation pressure is a gauge pressure and not an absolute pressure. This article focuses on cold inflation pressures for passenger vehicles and trucks. The general principles are, of course, applicable to bicycle tires, tractor tires, and any other kind of tire with an internal structure that gives it a defined size and shape (as opposed ...
