Recently I got me CEL again, after I parked my car outside for one night...
Then it just on and off from time to time for about one week or 2 already.
I had it scanned and found only one code (I forgot...), and it's about the air intake master flow sensor.
I did use a short ram intake before but changed back to the stock box with a KnN filter only for a long time.
And the on-n-off CEL, I found something insteresting, looks the cold temperatures under the hood will turns it on. And a warmer temperature will do good to it. E.g. after clear the code with the scanner, if I keep using the car, the CEL will not turn on again. But after I park the car for enough long time to get the car cold down completely, the light will turn on... We got some days a little bit warmer, the light will also have a chance to turn off by itself...
Any idea about it? Thanks so much for your input in advance!!
I asked the price for replacing the flow sensor, it costed! Original OEM will be above 200, or Denzo brand for about 180... If I do need a new sensor, I want to confirm if paying this money is a must do....
