Then turn the motor very slowly with a screwdriver in the #1 cylinder until you just feel the piston come to rest up top, and just before you feel it going down. Take a 21mm socket and put it on the crank pulley. This is the point where you need to stop.

(did that before, not fun, i hate shocks) Have a buddy bump over the motor until you can feel air blow out of the hole. Disconnect the plug on the coilpack so you won't get jolted when you take off the plug wire on the #1 cylinder. Double check the ensure the car won't start by listening to see if the pump kicks on when you turn the key on. Take out your fuel pump fuse in the PDI box. If the vehicle has a more complex engine, it may have more than one camshaft position sensor attached.You do not need a compression gauge. However, some later models require their own power source and generate a digital signal to provide the data. The most common type of sensor is magnetic and generates its own alternate current signal that is sent to the electronic control module. These sensors are designed to provide highly accurate data, especially when an engine is operating at high speed. These sensors provide a different array of data to the other important positioning sensor linked to the crankshaft, which is designed to help control the ignition timing and speed of the engine itself.Įach sensor has advanced circuitry that is designed to operate in stressful or hostile environments and to resist powerful spikes or electromagnetic forces. The reading mechanism is designed to determine how the cylinders are moving, to precisely synchronize how fuel injectors or electronic coils activate. The camshaft positioning sensor is usually fitted into the cylinder head of the motor. How Does the Camshaft Position Sensor Work?
