The Crankshaft-Camshaft CPS Sensor serve the same purpose as the ignition pickup and trigger wheel in an electronic distributor.
The big difference being that the basic timing signal is read off the crankshaft instead of the distributor shaft.
So, CPS Sensor produce a signal that talks to the Fuel Injection Computer or the Ignition Control Module. As a result, They relay the exact position of the pistons as they come up or go down in the compression cycle.
The Crankshaft-Camshaft Sensors is a small, but significant, magnetic device. And, It gathers and sends information about the car’s camshaft speed to the car’s electronic control module.
Consequently, , It uses this data to further calculate the timing of ignition and fuel injection required by the engine. As a result, This information is vital for engine function.
The O2 Sensor is usually on the crankshaft near the main pulley. It passes on information and when things begin going south, it needs immediate attention.
