Understanding Crankshaft Position Sensors
Modern engines need to know the position of the crankshaft and camshafts. Why? The timing of the valves, fuel injectors and ignition coils are continually optimized for the most efficient combustion event depending on the load and speed of the engine. But the other reason for knowing the position of the crankshaft is for misfire detection.

Diagnostic Dilemma: The Case of the Missing Code
When doing mobile diagnostic work, no-code stalling complaints are a major part of your agenda. In most cases, the client shop is simply too busy to duplicate the failure or, in some cases, a long test drive will yield nothing in the way of useful scan tool data. With many no-code stalls, all you’re going
