Hello. My engine light came on and I took it to Auto Zone where they do the free engine light diagnosisand the results came out to be 4 possibilities:Car: 2000 Nissan Sentra GXEPossibility 1: Faulty fuel capPossibility 2: Purge system leakPossibility 3: Faulty canister vent control valvePossibility 4: Faulty purge control valveI‘d like to narrow this down to one possibility, and I‘m willing to take the car apart to check things out. Is there anything I can do or look for to tell which possibility is the true problem? Thanks
Because when you brake the force and weight goes to the front of the car . giving more stoping power to the front! your front brakes will always weir out faster no matter what the drive is
Disc brakes are easier to replace than brake shoes. You failed to mention what kind of car you drive, so I don't know for sure how easy it will be. Front brakes are your primary stopping power and they will wear out faster. Front brakes +- 40,000 miles. Rear brakes +- 70,000 miles.
purely clearing the code could no longer be the respond if the code is reflecting a genuine situation. Your vehicle can be due for oxygen sensor substitute. After a on an identical time as the oxygen sensors placed on your exhaust get lined in carbon and don't study wisely which motives the computer to work out a situation that would not truly extist. it fairly is easily basically a wager, it truly does could be acceptable to take it to the broker or a relied on technician.
It's actually almost always the fuel cap. On a 2000, that cap has been removed a ton of times. You have an emissions code sensing a leak somewhere. Not only is that a common problem, it's a really cheap fit; you can find Stand gas caps everywhere, including AutoZone. That would be my first step. Once you replace the cap, you'll need to have the code cleared, and drive a couple of cycles to make sure the code does not come back. It usually won't re-appear right away, so don't get excited right away.
all you can do is visually check the EVAP lines for cracks, or check the fuel cap and make sure it's tight. you would need a scanner and a smoke tester to find a faulty part.
