The P0019 Code is generally connected with the Camshaft Position Correlation (Bank 2 Sensor B). This diagnosis trouble code is found in many vehicles. Both crankshaft position sensor and Camshaft position sensor work in proper synchronization to control the spark or fuel delivery and timing. They both consist of a relator, ring which passes over a magnetic sensor which produces a voltage indicating position. The P0019 Code generates due to some reasons and some symptoms are Malfunction Indicator Lamp (MIL) illumination, the engine may run but with compact presentation etc. There are different causes involved like bad cam and crank sensor, broken wiring to cam or crank sensor etc.
