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.
Check Engine is blinking or lit on the dashboard. Few people are optimistic about this. However, there is no reason to panic. The Check Engine light on the second-generation Ford Focus often lights up, but there is no tragedy in it. In almost 90% of cases, actuation of the emergency lamp is caused by trifling reasons, and it is possible to eliminate them with bare hands. Yes, sometimes there are serious breakdowns, but we will try to cover the widest possible range of faults in Ford Focus 2, which causes the check light.
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.
On Nissan Teana, X-Trail, Note, Peugeot and Citroen engines produced before 2011 and a lot of other cars the Check Engine warning light or the scanner generates failure code P0011 often lights up. At the same time, the Check Engine may not light up, but the symptoms of malfunction are obvious. How to act in such cases, how to reset and find out the causes of the OBD 2 code, we will understand right now.
The Check Engine light came on, and it can really affect our plans and financial expenses. An inexperienced driver is confused: does this mean that the trip is canceled? Or is there a simple solution to the problem? Without an expensive trip to the service station, there is only one way to find out why the Check Engine light came on: an OBD-II scanner.
The battery charging system on the Ford Focus II rarely fails. As a rule, the main sign of malfunction is a voltage drop at the output from the alternator or at the output from the engine control unit. All this is accompanied by a burning alarm lamp on the dashboard (with the image of the battery), and when scanning the system pops up error P1246, the failure of the input load circuit of the alternator. Let's deal with the error on the Ford Focus 2 together.
Errors diagnosed by mobile scanners and computers in one way or another indicate a malfunction in the engine management system. And these errors are not always duplicated by the Check Engine icon. In the case of the common error u1900 check lights up very rarely and most owners of Ford Focus 2 are surprised to find this OBDII code only when scanning.
