Where is the camshaft synchronizer located on a car?
The the Camshaft Syncro Shaft (Camshaft Synchronizer) is on the top back passenger side of the engine. There is a hold down bolt (#3 in diagram below) that holds it in place. The Camshaft Position Sensor is attached to the top of the Camshaft Sycro Shaft.
Why are camshaft synchronizers necessary for sequential fuel injection?
Theories/Speculation. Camshaft synchronizers are most especially necessary for sequential fuel injection (also known as SFI), to function efficiently and properly. The synchronizer assembly has sensors attached to the top of them, and the sensors must be taken off to allow timing of the assembly as well as installation of the synchronizer.
What happens when the cam Syncro sensor is left unchecked?
If left unchecked, the bushings will continue to wear to the point where the metal flag that is supposed to pass through the cam position sensor contacts the sensor. This puts a sudden halt on the cam syncro shaft. The gear that engages the camshaft itself is attached to the cam syncro shaft with a roll pin.
What causes the cam Syncro shaft to disengage?
The gear that engages the camshaft itself is attached to the cam syncro shaft with a roll pin. The force of the cam syncro being stopped and the cam still spinning either rips the teeth off the gear or sheers the roll pin…either case causes the cam syncro shaft to disengage the cam.
