CMP sensors are used on all current model year engines, regardless of fuel system or ignition system type. The CMP sensor provides the Powertrain
Control Module (PCM) with cam position information to indicate # 1 cylinder, on the compression stroke
There are two different types of CMP sensors:
^
The three-pin, Hall-effect sensor (Figure 1)
^
The two-pin Variable Reluctance sensor (Figure 1)
Although the Hall-effect (three-pin) and the Variable Reluctance (two-pin) CMP sensors perform the same function, their signal appearance is quite
different and they are not interchangeable.
