Grand Caravan FWD L4-2.4L VIN B (1997)
The crankshaft position sensor mounts to the engine block behind the generator, near the oil filter (Fig. 8).
CIRCUIT OPERATION
Circuit K7 supplies 8 volts from the Powertrain Control Module (PCM) to the crankshaft position sensor. The K7 circuit originates at cavity 44 of
the PCM connector.
Circuit K24 from the sensor provides an input signal to the PCM. The K24 circuit connects to cavity 32 of the PCM. On vehicles equipped with an
electronically controlled automatic trans axle, circuit K24 splices to the transmission control module.
The PCM provides ground for the crankshaft position sensor signal (circuit K24) through circuit K4. Circuit K4 connects to cavity 43 of the PCM.
Helpful Information
Circuit K7 also splices to supply 8 volts to the camshaft position sensor and vehicle speed sensor.
Circuit K4 also splices to supply ground for the signals from the following:
-
Upstream heated oxygen sensor
-
Downstream heated oxygen sensor
-
Camshaft position sensor
-
Throttle position sensor
-
Manifold absolute pressure sensor
-
Engine coolant temperature sensor
