What causes the P001622 intake camshaft position delay?

[McMarcus]

P001622 intake camshaft position delay may be caused by timing errors, damaged variable timing solenoid valve, or faulty intake camshaft position sensor. The crankshaft position sensor is one of the most critical sensors in the engine electronic control system, providing signals for ignition timing and confirming crankshaft position, used to detect piston top dead center, crankshaft angle, and engine speed. Below is the removal method for the crankshaft position sensor: 1. During removal: Disconnect the sensor wiring from the main harness near the rear of the intake manifold. 2. Nut: Remove the nut securing the crankshaft position sensor wire clamp on the fuel pipe mounting bolt, then remove the crankshaft position sensor mounting bolt. 3. Sensor: Remove the crankshaft position sensor and detach the wiring harness clamp for the crankshaft position sensor.
