Do you have to remove engine to replace camshaft?
Installing a camshaft is a routine repair that many tuners and mechanics enjoy. It’s less work if you have a hoist, but the lack of a hoist will not prevent you from performing this repair. You can replace the cam with the engine in the car by removing the radiator, grille and brackets to provide access.

What is the purpose of the camshaft sensor?
The camshaft position sensor, in conjunction with the crankshaft position sensor, serve the function of cylinder identification. By knowing which cylinder is approaching top dead centre, the engine ECU can adjust fuel injection timing or when to energise the ignition coils to enable a smooth combustion process.
What does a camshaft sensor do?
The camshaft position sensor gathers information about the vehicle’s camshaft speed and sends it to the vehicle’s engine control module (ECM). The ECM uses this data to determine the timing of the ignition, as well as the timing of the fuel injection that the engine requires.
How does a camshaft position sensor go bad?
As the camshaft position sensor weakens, the signal it transmits to the vehicle’s ECM also weakens. Eventually, the signal will weaken so much the signal will switch off, and so will the engine. This can happen while the vehicle is parked, or while you are driving. The latter can be a dangerous situation.
