ABSTRACT:
A multi-test, hand-held instrument and method for testing manifold absolute pressure (MAP) and mass air flow (MAF) sensors includes a housing enclosing a battery and an electrical circuit. The electrical circuit can test d.c. voltage output signals and frequency output signals from MAP/MAF sensors and can test continuity and battery strength. Electrical leads extend outwardly from the housing and are connectable to the sensor being tested. A pair of light indicators, comprising LEDs and resistors connected in parallel, are selectively illuminated to allow the test instrument to be used to test both MAP and MAF sensors, and to test these components on different makes and models of vehicles.
