   The Society of Automotive Engineers (SAE) recommends a standardized diagnostic connector and set of diagnostic test signals. ~1994: Motivated by a desire for a state-wide emissions testing program, the CARB issues the OBD-II specification and mandates that it be adopted for all cars sold in California starting in model year 1996 (see CCR Title ...

4. MAP sensor - Wikipedia

   en.wikipedia.org/wiki/MAP_sensor

   The manifold absolute pressure sensor (MAP sensor) is one of the sensors used in an internal combustion engine's electronic control system. Engines that use a MAP sensor are typically fuel injected. The manifold absolute pressure sensor provides instantaneous manifold pressure information to the engine's electronic control unit (ECU).

5. Engine control unit - Wikipedia

   Fuel pressure regulator; Rev limiter; Wastegate control and anti-lag; Theft prevention by blocking ignition, in response to input from an immobiliser; In a camless piston engine (an experimental design not currently used in any production vehicles), the ECU has continuous control of when each of the intake and exhaust valves are opened and by ...

6. Jetronic - Wikipedia

   en.wikipedia.org/wiki/Jetronic

   The fuel distributor is mounted atop a control vane through which all intake air must pass, and the system works by varying fuel volume supplied to the injectors based on the angle of a moving vane in the air flow meter, which in turn is determined by the volume of air passing the vane, and by the control pressure. The control pressure is ...

7. Head gasket - Wikipedia

   en.wikipedia.org/wiki/Head_gasket

   Common test methods for head gasket leaks are a compression test (using a pressure gauge), a leak-down test or a chemical test that identifies hydrocarbons in the coolant fluid. [ 5 ] The cost of the replacement component (i.e. the head gasket itself) is usually relatively low, however there are significant labor costs involved in the ...
