How does the CIS fuel injection system work?
Unlike pulsed-injection systems like the Motronic system or even the earlier Mechanical Fuel Injection system, the CIS injectors distribute fuel to the cylinders at all times. The opening and closing of the intake valves controls the intake of fuel into and out of the combustion chamber.
How does the CIS work on a Porsche 911?
The CIS meters the amount of fuel provided to the cylinders as a function of the air drawn into the engine. The CIS air flow sensor plate measures the amount of air that is being drawn into the system. This sensor plate is attached to a fuel distributor that evenly meters the amount of pressurized fuel sent to each injector.
How do you test a CIS fuel pump?
Using a CIS fuel pressure tester, verify the proper operation of the fuel pump by measuring the pressure when the ignition is turned on. The pressure measurements need to be taken at specific times, and at varying engine temperatures.
When did Porsche start using CIS fuel injection?
The system in general is very reliable, and was only bested in 1984 by the introduction of the Motronic engine management system that controls both ignition and fuel injection together. The CIS meters the amount of fuel provided to the cylinders as a function of the air drawn into the engine.

Stalling, surging, or hesitating while idling all can be caused by this unassuming sensor. The best way to determine if these issues are caused by your throttle position sensor is to go to the source.
How does the throttle position sensor work on a car?
This vital sensor allows your engine to maintain a proper amount of air. This feature is dependent on the throttle valve. When you press down on the gas pedal, your throttle body unit’s valve opens. This causes your throttle position sensor to adjust the engine intake manifold accordingly.
What happens when you press down on the gas pedal?
Engine response is inconsistent When you press down on the gas pedal, your engine should respond directly and instantly. However, when a problem with the APP sensor exists, the vehicle’s ability to consistently accelerate or decelerate as directed by the driver is reduced.
