What causes the slow response of the exhaust camshaft position in Volvo XC60?

[VonTeagan]

Volvo XC60's slow response of the exhaust camshaft position could be due to a damaged camshaft position sensor or weak signal, requiring professional inspection. The camshaft position sensor is a sensing device, also known as a synchronization signal sensor. It serves as a cylinder identification and positioning device, inputting camshaft position signals to the ECU, which is the main control signal for ignition. Relevant information about the camshaft position sensor is as follows: 1. The function of the camshaft position sensor is to collect the camshaft's dynamic angle signal and input it into the electronic control unit (ECU) to determine the ignition timing and fuel injection timing. 2. The camshaft position signal is used to identify the first ignition timing when the engine starts. Because the camshaft position sensor can identify which cylinder piston is about to reach the top dead center, it is also called a cylinder identification sensor.
