Code P2090 Volkswagen Description

The camshaft's task is to operate the valves at the right time and in the right order to control the charge cycle. Camshaft adjustment using the Camshaft Adjustment Valve 1 varies the opening times of the valves to suit all operating conditions. This ensures ideal charge cycles within a wide range of engine speeds and loads. Fuel consumption and pollutant emissions are reduced, torque, and smoothness increased. In engines with a double overhead camshaft, the size and positioning of the valve opening overlap can be influenced, enhancing characteristics in full-load and part-load operation. In continuous camshaft adjustment, the adjustment is infinitely variable within specific parameters. The Diagnostic Trouble Code (DTC) will set when the Diagnostic Trouble Code (DTC) circuit is not to factory specifications.
