| The fuel injectors (see pic above) are electrical solenoids (switch valves for liquid) that allow the flow of pressurized fuel from the electric fuel pump. The injectors spray fuel (like a hose nozzle) into the intake manifold air tract. | The fuel injectors (see pic above) are electrical solenoids (switch valves for liquid) that allow the flow of pressurized fuel from the electric fuel pump.

| If you are able to observe the above voltages from the sensor, but the speedometer is still erratic or otherwise malfunctioning, be sure to test all the wiring between the sensor and the speedometer. As a last resort, replacement of the speedometer may be in order. | If you are able to observe the above voltages from the sensor, but the speedometer is still erratic or otherwise malfunctioning, be sure to test all the wiring between the sensor and the speedometer.
