Basic DTC analysis according to OBD2 protocol standard.

OBD2 or On-Board Diagnostics displays messages for basic group styles. More comprehensible code composition has been standard since 2000. The DTC code consists of five characters and its composition will be shown in this video

Insight into programming

The basic unit for the operation of any computer is the bit. Logic 0 and 1 are expressed by a single bit. Diagnostics The error code is composed of 16 bits. The first two bits define one of the four basic circuits. The video will show you a comprehensive overview of the composition of the error report

Cause of DTC

The Variable Valve Timing (VVT) system continuously varies the Camshaft target position based on the engine operating parameters. Based on these parameters, the Powertrain Control Module (PCM) calculates or models the optimum Camshaft position. The Camshaft angular position is varied by the oil control valve. The VVT solenoid pushes on a plunger (spring loaded spool valve) in the center of the Oil Control Valve (OCV) which directs oil pressure to the hydraulic actuator (Phaser) on the Camshaft Sprocket to change the Camshaft position relative to the Crankshaft position. The VVT Solenoid, acting on the Oil Control Valve and Phaser, is controlled by the PCM. The Camshaft Position (CMP) Sensor is used to monitor the position of the Camshaft.
