Question:

my 2001 ford tauruss emission control system light is on,what can it be?

I checked the manual and that‘s what it says, it was hard for me to understand exactly what the problem is. I filled my gas tank up to over 1/2 a tank and it‘s good,all the oil levels are fine.I did drive on a dirt road a day before I saw this light pop up. How can I take this light off if everything seems to be fine?

Answer:

One of my pet gripes is that the emission control system in most cars will not say what is wrong, just that something is wrong. If you live in the US outside of California you can take the car to most auto parts chain stores (like Auto Zone) or to Aamco Transmission and they will read the code for free, and try to reset it if the code is temporary. In California only authorized auto service shops are allowed to do that. no comment on the sensibility of that.
You need to have the code read with a scan tool to find the exact problem your car is having, there are different sensors for the emissions system. You might just have a bad oxygen sensor.
i ought to have pronounced to verify the Crankshaft place Sensor, yet pondering its in uncomplicated words a #one million cylinder backfire that relatively a lot regulations out the CPS. My 2nd and third suggestion could have been to bathe the MAF sensor and replace the IAC valve. you need to now no longer sparkling the IAC valve effectively, yet for 60 dollars purchase a sparkling one and setting up it pondering its a 2001 its due for one as properly. They improve carbon and get ruined like that. additionally in case you have an ohmeter, you need to attempt that MAF sensor to artwork out interior the journey that your getting a interpreting indoors specs. i ought to wager money on the two components you already wiped sparkling. you particularly ought to swap that IAC and MAF sensor. additionally double analyze the wires from the two sensors and make optimistic that they at the instant are no longer frayed or have uncovered twine to the ambience. which will reason subjects you're describing as properly. enable me be attentive to the way it is going.
