See the basic definition of a diagnostic error. This will help you to clarify the main causes of the fault code. You will understand the program of the control unit
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

DTC P0201, P0202, P0203, P0204, P0205, P0206, P0261, P0262, P0264, P0265, P0267, P0268, P0270, P0271, P0273, P0274, P0276, P0277, P2146, P2149, P2152, P2155, P216A, or P216D is not set. The engine is greater than 240 RPM. The ignition voltage is greater than 10 volts. The HO2S 1 heater duty cycle is greater than 90 percent for greater than 5 seconds. The DTCs run continuously once the conditions above exist for greater than 60 seconds. Condition 3 Before the ECM can report that DTC P0130 or P0150 failed, DTCs P0030, P0031, P0032, P0050, P0051, P0052, P0133, P0135, P0153, and P0155 must run and pass. The engine is operating. The ignition voltage is greater than 10 volts. The air flow into the engine has exceeded 10 grams. The HO2S 1 heater duty cycle is greater than 70 percent or, the calculated exhaust gas temperature is warmer than 600°C (1,112°F). Closed loop fuel control is enabled. The evaporative emissions system (EVAP) is not performing an intrusive test. The DTCs run continuously once the conditions above exist for greater than 30 seconds.
