2. Oil pressure - Wikipedia

   en.wikipedia.org/wiki/Oil_pressure

   Excessive oil pressure may indicate a blocked filter, blocked oil gallery or the wrong grade of oil. Low oil pressure indicates worn bearings or a broken oil pump. Some vehicle engines have an oil pressure switch that switches a warning light on at low oil pressure. Some vehicles have an oil pressure gauge in the dashboard or instrument cluster.

3. Tell-tale (automotive) - Wikipedia

   en.wikipedia.org/wiki/Tell-tale_(automotive)

   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 ...

4. Oil pump (internal combustion engine) - Wikipedia

   en.wikipedia.org/wiki/Oil_pump_(internal...

   Indications of low oil pressure may be that the warning light is on, a low pressure reading on the gauge, or clattering/clinking noises from the engine. Low oil pressure is a problem that must be addressed immediately to prevent serious damage. The leading cause of low oil pressure in an engine is wear on the engine's vital parts.

5. Check engine light - Wikipedia

   en.wikipedia.org/wiki/Check_engine_light

   A check engine light or malfunction indicator lamp (MIL), is a tell-tale that a computerized engine-management system uses to indicate a malfunction or problem with the vehicle ranging from minor (such as a loose gas cap) to serious (worn spark plugs, engine problems or a faulty oil valve, etc.).

   An annunciator panel, also known in some aircraft as the Centralized Warning Panel (CWP) or Caution Advisory Panel (CAP), is a group of lights used as a central indicator of status of equipment or systems in an aircraft, industrial process, building or other installation. Usually, the annunciator panel includes a main warning lamp or audible ...

   Tire warning light on a car dashboard. But in cold weather, the TPMS may trigger a warning because of something completely natural. The air inside a tire condenses in colder weather, taking up ...

8. Pressure switch - Wikipedia

   en.wikipedia.org/wiki/Pressure_switch

   A pressure switch is a form of switch that operates an electrical contact when a certain set fluid pressure has been reached on its input. The switch may be designed to make contact either on pressure rise or on pressure fall. Pressure switches are widely used in industry to automatically supervise and control systems that use pressurized fluids.

9. Tire-pressure monitoring system - Wikipedia

   en.wikipedia.org/wiki/Tire-pressure_monitoring...

   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).
