WARNING: This page is about a different car, the 2004 Dodge Sprinter. However, it is still accessible from the selected car via links, so may be relevant.

The ECM uses the intake air temperature sensor, engine temperature sensor and the crankshaft position sensor (engine speed) inputs to determine fuel injection quantity.
