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

Cause of DTC

DTC P0101, P0102, P0103, P0112, P0113, P0117, P0118, P0120, P0121, P0122, P0123, P013A, P013B, P013E, P013F, P0171, P0172, P0220, P0222, P0223, P0300, P0335, P0336, P0365, P0366, P0442, P0443, P0446, P0449, P0455, P0496, P0506, P0507, P1381, or P2135 is not set. Before the ECM performs the idle test, the vehicle must be driven under the following conditions: The engine speed is greater than 1,000 RPM The engine run time is greater than 10 minutes Both conditions exist for greater than 1 minute The throttle is in the rest position. The intake air temperature (IAT) is between -20 to +85°C (-4 to +185°F). The ignition voltage is greater than 11 V. The engine coolant temperature (ECT) is between 45-129°C (113-264°F). The barometric pressure (BARO) is greater than 70 kPa. The catalytic converter calculated temperature is less than 900°C (1,652°F). The vehicle speed is less than 2 km h (1 mph). The short term fuel trim is learned. The short term fuel trim (FT) is between -10 and +10 %. The engine is operating in Closed Loop. The transmission is not in P N (automatic transmission only). This diagnostic attempts one test during each valid idle period once the above conditions have been met. This diagnostic attempts up to 6 tests during each drive cycle.
