WARNING: This page is about a different car, the 2017 Jeep Patriot and 2017 Jeep Compass. However, it is still accessible from the selected car via links, so may be relevant.

The PCM uses the engine temperature sensor and the crankshaft position sensor (engine speed) inputs to determine fuel injection quantity.
