check engine light part 1

-
When you see a this light on your dashboard ,your car is telling you that there is something wrong with your engine and it demands you to check it pretty fast.
This can vary from emission system malfunction to misfiring of the cylinders to low fuel pressure and so on. In this article we will be talking about P0174. P0174 is the trouble code the OBD II would bring out when you probably notice that your fuel intake is higher than normal, although there are many causes of this symptom.
P0174 means that the oxygen sensor bank 2 has detected too much of oxygen in the exhaust ( a lean mixture).
Possible causes of P0174
1. Intake air leaks
2. Faulty front heated oxygen sensor
3. Ignition misfire
4. Exhaust gas leaks
5. incorrect fuel pressure
6. lack of fuel
7. faulty MAF, mass flow sensor.

Possible Solutions
1. change the Air filter
2. Clean the MAF sensor
3. Check for leakages in the air system
4. Clean the injectors

Mind you, the brake pad is made of materials that wear off easily in other to make the brake rotor (disc), which is more expensive, not to wear off easily while in braking and also to reduce energy loss due to heat caused by friction (We will talk about the essence of brake pads and brake pad materials in our teaching). So if you have a brake pad that doesn't wear off then you bought yourself a damaging tool. Here are the different brake wear indicators on an automobile: 1. Ocular brake indicator: this are grooves made on the brake pad. One must constantly check the brake pads to know when the brake pads flattens with the grove. 2. Mechanical metal plate indicator: A metal plate is attached on some brake pads so that when the brake is due for change the plate can touch the surface of the d...
