You have to break the law in order to reset your EVAP Monitor on you Car? 04 12 2024

 So if you need a new battery in your car or you need to have the battery in your car charged and disconnect the battery in there, the EVAP Emission monitor will go into a non tested mode that will fail the emissions test.  But if you then put that car through a "drive cycle" or more than one that EVAP Sesnor system is likely going to reset itself.

But more required drive cycles say something like this.  Warm the car up for two and one half minutes with many electronics on, like ac and rear defroster.  Then increase speed to 55 mph and hold it for 3 minutes then take your foot off the peddle and decrease to 20mph (and do not put your foot on the brake when doing this)  , then increase the speed again to perhaps 55mph and drive for five to eight miles.  But right there when you slowed to 20mph that speed was likely lower than the low limit on the highway you were on?  Slow down unnecessarily and didn't see the driver behind you?

Now my official car repair manual states it is impossible to understand the EVAP system unless you have the right tools, perhaps a $10,000.00 red diagnostic machine the size of two refrigerators welded together and the proper specific training?  Ask yourself what that really means?

So why can't you just go into a $15 obd2 tool and "ask" it to run an EVAP monitor test?

Because the EVAP test has either a pressure pump or vacuum pressure pump on your car that is uses to pressurize or decrease the pressure in your "gas tank system?"  And in doing so you might have, under specific circumstances, created and detonated a bomb out of your car in doing so? And this is all speculation.

If you were able to do that test yourself, you might create a bigger leak in a tank?  And then you would have a problem?  Whereby a trained mechanic would have looked at a checklist that is included on first before clearing it to be in ready monitor?  All pure speculation.

To me it reads like an issue whereby a mechanic at the dealer can tell you that you need a new car or expensive repairs that you really don't need?  Do dealer mechanics get a slice of the pie if they say you need a new car in subjective cases?

Some of the drive cycle criteria for the cars computer running the test might be that the temperature outside is between 40 and 90 degrees?  All well and good but in WI for half the year it won't be? 

I understand that this test is needed.  I agree with the importance of it.  But why not make it so that you haven't put the United States Citizen between a rock and a hard place?
