If you have an Autozone near you they will put a tester on it for free or a place or parts store that sells testers and that way you can find out why the check engine light is on because it could be several things that can cause this light to be on

What does it mean wen i change my fuel fillter and fuel pump and it dieds wen i let off the gas

If you do not have a vacuum leak in a hose. then check the idle air control because this is what regulates the idle and sends this info to computer. You may have to take it off to clean it or replace if bad. Good-Day!

Check engine light code says MAF sensor

Could be wiring to the MAF. Did you replace it with a new one? I know that might seem silly but people do put used ones on.

P0100 - Mass Air Flow (MAF) Circuit Malfunction

Basically this means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. Other MAF sensor circuit DTC trouble codes are P0101, P0102, P0103, and P0104.

You will likely not notice any serious drivability problems, although there may be symptoms such as a general decrease in power or sluggishness.

Causes: A code P0100 may mean that one or more of the following has happened:
* The MAF may be disconnected, or a wiring connection may be bad
* The MAF sensor may be faulty

Possible Solutions: The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:
* Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
* Unplug and reconnect the MAF wiring harness
* Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
* Replace the MAF sensor

Then, like a reference guide check this TSB DTC P0102 MAF and this article about Mass Air Flow sensor, what does it do and how it does it.
Test, check it and keep us updated.

My check engine light is on and i was told it's code po102. What does that code mean is the reason the light is on?

A code P0102 may mean that one or more of the following has happened:

  • The MAF may be disconnected, or a wiring connection may be bad
  • The MAF may be dirty or otherwise contaminated (Note: if you use a reusable oiled air filter, be careful not to apply too much oil or that can contaminate the MAF).
  • The MAF sensor may be faulty
  • The vehicle computer may be faulty (very rare)
You most likely will need to replace the car's Mass Air Flow (MAF) sensor. It measures how much air is entering the engine. They usually cost ~$100 for the part

Wat do check engine soon mean wat can be my problem

Could be a bunch of things most likely some sort of emissions sensor. If you are close to an "Autozone" they can check the codes for you for free and this should tell you what is setting off the sensor
