That hasn't cleared codes since at least '96 model year. You'll need a scan tool or code-reader to clear the codes.


Evap system is often a failed (or loose) gas cap. Can be lots of other stuff, but often the cap.

How old are the O2 sensors?
I replaced both O2 sensors with the new cat converter... the P0172 code cleared itself before I got to Orily's so im guessing there was just excess fuel in the system because of the faulty cat and stuff... I also bought a new gas cap so we'll see if that code pops back up after I drive it around a bit

Do you mean to tell that there was excess fuel in the exhaust system and that's your problem?

Bat guano!


Where do these ideas come from?

There was a recall on some Envoy's, TB's likely also, for a plastic part in the fuel filling system, that may crack and allow it to act like a bad fuel cap. Just a thought . . .

Well it looks like all my codes are gone after having Oriley's clearing them and ive driven around the last couple days and just did a 3 hour round trip to take my friend home with 0 issues... Guess at this point I just have a break job and ABS module change out to do and I should be good to go

Congrats!

Now splurge and get yourself an inexpensive, yet capable OBDII code reader/live data scanner. If you have an android device, I recommend this set up - a certain Bluetooth OBDII dongle and the Torque Pro app. Total cost is under $25.00


I use this setup and I am amazed at all it can and will do, and I am not even using it to it's full potential.

Good Luck!

I have a Automend Pro OBDII sensor already hence how ive been finding all my codes while trying to get this damn thing fixed lol... On a side note, does anyone know where I can find a new overhead DVD player for the 2nd and 3rd row seats? Mine was completely shot and I want it for the trip lol

Glad to hear you have a code reader/scanner.

I do not have a clue for the DVD player other than a junkyard or Crutchfield.com

Good Luck!

A dongle plus your smart-phone. The web-site is the text equivalent of a late-night TV infomercial. Very shady. Wildly overpriced.

They're big on telling you it does what you need...without ever telling you what it actually does. Apparently, it's a cheap consumer-grade code reader.

I love the "fine print' at the bottom of the page:

Also, just some general questions cause this is the first time ive had a vehicle like this... Theres a button on the dash for TC (which I assume is traction control) and by default its on... Does it need to be or can I disengage it when I am not towing things? Also does the 03 model have cruise control? Theres a button on the steering wheel that looks like a road but when I press it nothing happens... Not sure if that means its either broken or the fuse for it is blown but yeah... Still trying to learn the features of this vehicle... Especially if the damn thing has 4WD or if its AWD/2WD

The point is, "codes" are NOT ENOUGH, and why I'm so peeved at crooks that take advantage of people by advertising code-reader junk as if it were The Ultimate Solution to whatever problem the vehicle has.

Having access to the data stream--"Live Data"--and some bi-directional control is more useful than "codes" at least half the time, and maybe more. "Codes" are often helpful, live data is ESSENTIAL.

For regular daily driving I should just be in 2WD yeah?
Yes.

Cruise control should be on the turn signal lever. A slider-switch for Off--On--Resume/Accelerate; and a button on the end to Engage or to slow down.

The "roadway" on the pushbutton on the steering wheel is likely for the Driver Information Center (DIC) in the instrument cluster, and not all vehicles have that. Those that do, can display the odometer reading, trip odometer, trip timer, estimated instant or average fuel economy (MPG), mileage until the gas tank is empty, (range to empty) and some other info.

I can't help with the TC button. Mine doesn't have that. However, there's no reason to turn it off in normal driving. You might have to turn it off in special circumstances.

May I suggest buying or downloading a copy of the Owner's Manual?

I bet most folks have absolutely no idea what that image is.

But we old codgers remember TV test patterns. That, and the National Anthem being played when the station went off-the-air at midnight or 1 am.

I mean I was born in 95 and I know what it was xD Luckily I am educated in the better ways of the old people... I prefer music like Johnny Cash and Ozzy over modern music... at least back in the day artists had talent and not auto tuners...

Going back to the topic of the code reader, mine does do the live data as well as well as an emissions precheck and a few other handy things

Interesting that they make no mention of live data; or show any sensor data on the web page.

K so the P0442 came back (small evap leak) and I already replaced the gas cap... so not sure what to do

Edit: Research shows either the EVAP Solenoid or the Filler Neck need to be replaced... but I think Im going to take it somewhere to do a smoke test to see where the leak is coming from... fingers crossed its a simple hose

The smoke test is the right thing to do before tossing parts at the problem! It could be one of the two things you mentioned, or it could be a crack in one of the EVAP lines, or an EVAP Purge Valve solenoid or the EVAP Vent Valve solenoid not closing all the way.

Yee, I set an appointment with a mechanic to do the smoke test to figure out the problem... Depending on what it is I may just pay for the labor to have it fixed cause im so tired of doing the handy work myself after that damn cat lol

Oh how well I understand! Replacing EVAP parts is not that difficult (especially when you have a lift), so labor time should not be that much. Now parts mark up is another matter.

Good Luck!
