Ninety-Eight V6-3800 3.8L Supercharged (1993)
Camshaft Position Sensor: Description and Operation
Camshaft Sensor
The cam shaft sensor is located on the timing cover behind the water pump near the camshaft sprocket. As the camshaft sprocket turns, a permanent
magnet activates the Hall-Effect switch in the cam shaft sensor. When the Hall-effect switch is activated, it grounds the signal line to the DIS Module,
causing the cam sensor signal line applied voltage to go low. This is interpreted as a cam shaft signal. The camshaft signal occurs when piston #1 is
approximately 25 degrees After Top Dead Center on the power stroke. When the cam shaft signal is absent, a Code 41 will set.
