OBD:
The theory of the OBD is shown on the page OBD, OBD II, EOBD described. Every error code that is read with reading software from, among other things, the engine management system and is shown on the display has its own specific meaning. With the error code P0102 (air mass meter signal too weak), the fault must be sought in the direction of the air mass meter (defective lmm, defective plug or wiring) and with the error code P02A9 it is indicated that the injector of cylinder 4 is leaking.
The error codes provide a direction to investigate the malfunction. It should not be immediately assumed that an error code is the cause of the malfunction. It is possible that a lambda sensor failure is stored (P0130, Oxygen Lambda Sensor bank 1, sensor 1) when the cause is the vacuum leak in the engine inlet (eg a cracked crankcase ventilation tube). Too much oxygen is measured in the exhaust after combustion, causing the lambda sensor to malfunction.
This indicates that while the malfunction does provide a direction to look, the technician's expertise is all the more important. Replacing the crankcase ventilation tube will be the solution. Replacing the lambda probe will not correct the cause of the malfunction, so the malfunction will return.
There is a list of many different error codes available that applies to all cars. Each brand also uses its own specific codes (P1xxx). The general list is shown on this page. Certainly for the engine failures (which also includes the MIL, the Malfunction Indicator Light) there is a good chance that the code with the explanation will be mentioned in this list.
TIP! Many possible causes and solutions of error codes can be found on the site GerritSpeek.nl. There are also many tips and tricks that can be performed with the diagnostic software. mr. Speek specializes in the diagnostic software VCDS (VAG-com) and has collected a lot of information on his site over the years.
