What are the reasons for improper intake camshaft positioning?
1 Answers
The improper positioning of the intake camshaft may be caused by a stuck camshaft solenoid valve, which requires timely replacement; or misalignment between the camshaft and crankshaft. If this misalignment exceeds one gear tooth, the corresponding fault code will appear. The vehicle has high-voltage spark: But the starting time is prolonged, though the vehicle can eventually operate. During the starting process: Crankshaft reversal may occur, and backfire may appear in the intake manifold. Unstable engine idle: Severe shaking, similar to a cylinder misfire condition. Insufficient vehicle acceleration: The car cannot gain speed properly when RPM exceeds 2,500.
