Went to a pick and pull today, and found a 2007 Yaris Sedan. I pulled the evap canister and pump, but I still have the P043E & F faults. Not sure if the canister and pump I got are also faulty. I can’t put my old one, cause the mounting bolts broke in the housing. Sigh... there’s a 30 day warrantee for the canister and pump that I pulled, I might go back and exchange it for another that’s newer model. The other faults I think is an electrical issue. I wonder where their common points are? I think I’m giving up and gonna ask a pro for help.

sounds like a big mess, if you have skills to drill, you need to drill out the broken bolts and get the correct tap to clean the threads, i belive theyre 6x1.00, use a little anti seize when putting new bolts in, you also need to get a shop or the dealer to smoke test it for evap leaks, thats the easiest thing to do and go from there

I tried drilling the ones on the side with the pump, but I couldnít get it centered cause the pumpís in the way. I didnít want to unbolt the pump, I have a feeling theyíd break too. Iíll just leave it alone.
I wouldnít have removed the brackets from the one I pulled from the junkyard if they didnít charge for the brackets as well. I already bought new bolts for the canister that I got from the junkyard and yes, I put anti seize, I pretty much put it on almost everything. Iíll learn to keep the bolts from the junkyard next time. One of the weld nut, that secures the canister underneath, also broke off from inside the spare tire compartment. Sigh... Luckily itís one of the two on the driver side. I bought a replacement nut and bolt, but didnít bother putting it in yet, as Iíll be returning the canister for a replacement. Iím going to another LKQ, 45 min away, hopefully they have a better inventory. I called in and made sure I can return the part even if itís from another one of their site. Hopefully I find a Corolla or Matrix with rear disc brakes while Iím there. And of course an evap canister and pump thatís in better shape.
What did you mean by smoke test? The whole carís evap system or just the canister I pulled?

Have you put a voltmeter on your alternator? With all those codes, I'm wondering if you're having voltage delivery problems. Of course, you're not having drivability problems, so maybe not.

a smoke test will determine and pin point any evap sustem leaks, what you do is pinch off your rear vent by the gas tank and put the smoke tester straight into the evap system and you will see if theres smoke coming somewhere, is your car rusty? sounds like you have a lot of rust with all the bolts that are breaking. i would give your car a wd 40 bath before touching another fastener on that thing

Actually, I didn't... That's why I thought maybe my belt was slipping a bit. It passed the voltage test when I used the ODBII reader. I'll check right now.

The undercarriage is surprisingly not that rusty, but yes there are components that are, like the bolts that connected the midpipe to the header and axleback, and the bolts that held the evap canister.

I'll test my alternator first, like Adam said, if that's fine then I think I'm done messing with her and just head to the shop. Could it still be possible that my evap is fine and it's just faulting out because of electrical issues?

Ok, so I let her warm up to idle, took the negative cable off the battery, and read the alternator to ground, and she's making +14VDC. So that's not it...

YUP! I grabbed a 2012 Corolla evap canister, the related faults didn't go way. So I'm done trouble shooting. I'll post once the shop finds the fix. Stay tuned!
