DTC P0500 is typical not only for Ford Focus 2 cars, but also for many Japanese cars. Theoretically, there is nothing difficult to decipher, but the search for faults may lead very deep. Formally, OBDII code P0500 is deciphered as absence of data in the engine control unit about vehicle speed, therefore it would be logical to suspect the speed sensor. But it is not that simple.

The flashing Check Engine light warns the driver of malfunctions of the engine control system. In Ford engines, as in all modern injector cars, the engine is controlled by electronics. Testing the electronic control unit will help you understand what the error is. If the scanner or other diagnostic equipment indicates a P0300 error, it is most likely that we are dealing with a malfunction in the ignition system.

The engine needs clean air in the right quantity just as much as it needs fuel. The average ratio of oxygen to gasoline is 14.5:1. Hence, somehow this parameter needs to be controlled. That is what the mass airflow sensor does. Otherwise, we will get an engine malfunction, and code P0102 will appear on the scanner screen.

Regardless of whether the car is filled with gasoline or gas, it is not the pure fuel itself that burns in the cylinders, but the air-fuel mixture, since nothing can burn without oxidation. The oxidizer is oxygen from the air. You can not cheat physics and if the Check Engine lights up, and the scanner or diagnostic computer shows the failure code P0172, there are problems with the proportions of air and fuel in the combustion chamber.

Mysterious error codes, which are displayed on the scanners' monitors, sometimes baffle drivers. In fact, all car electronics simply fixes malfunctions, and we are left to deal with them ourselves. Error code P0171, which is produced by engines of Nissan, Mazda, Opel or Toyota, means that the mixture in the combustion chamber is too lean. Let's figure out how to reset the error and fix the problem right now.

OBD2 failure codes in the service menu on older Fords are common. Some codes may simply indicate the need to test the engine control unit, and some signal about serious problems. Many owners of Ford Focus II, C Max, Mondeo, and other models with 1.8 liter gasoline engine notice the appearance of OBD2 failure code P2008 when scanning the system. What is it, how to remove and reset the error, not to spend too much on repairs and replacement of expensive original parts, we understand right now.

Under normal conditions, any internal combustion engine, diesel or gasoline, needs to maintain a balance of oxygen and fuel. Fault code P2192 indicates that the fuel-air mixture is enriched, most likely at high rpm.
