Question on strange codes being thrown after replacing evap canister?

I have a 2010 5.7 tundra that was throwing the P0456 emissions slow leak code. After the dealer replaced the gas cap with a OEM toyota gas cap and not resolving the issue they wanted to replace my evaporative charcoal canister assembly. I didn't want to pay them the $500 on top of the $600 part so I ordered the canister myself and put it in (its really easy to get to and replace, btw). I ordered the canister off of Amazon from a Toyota dealership in Atlanta and it is an OEM toyota part. I double checked and the part number matches what is supposed to be in my truck.



After I installed it, I got another check engine light so I connected my OBDII reader up and got a list of 5 fault codes which are super odd:

1. P003D - Powertrain
   
   
2. P0900 - Powertrain
   
   
3. P1000 - Powertrain
   
   
4. P0041 - Powertrain
   
   
5. P0453 - Powertrain, evaporative emission control system pressure sensor high input
   

Now I could see where #5 would be linked to a evaporative canister (if I got a dud), but the other 4 codes are seemingly unrelated. The codes are on O2 sensors swapped between banks, something about camshaft sensor, and such. I can't think of any reason why installing a new canister assembly would trigger all of these codes. Any thoughts?

Update: After following a suggestion to reset the system via battery disconnect:
Well, unfortunately I don't think that did anything. I disconnected the negative terminal and left it off for ~60 seconds and reconnected everything. I drove back home today, all interstate, and averaged 11 mpg which is not good. I also plugged my scanner in again to see if there any of those codes still after resetting it and it came up with some new codes:

• P004D - Powertrain
  
  
• P1000 - Powertrain
  
  
• P0900 - Powertrain
  
  
• P0041 - Powertrain
  

so I cleared those codes and read it again and then it gave me:

• P0044 - Powertrain HO2S Heater Control Circuit High (Bank 1, Sensor 3)
  
  
• P1000 - Powertrain
  
  
• P004D - Powertrain
  
  
• P0900 - Powertrain
  

I am also noticing the fender over my tailpipe is turning brown which I'm assuming is from running rich - which it obviously is.

I just can't figure out how I can be throwing a bunch of weird random codes that have nothing to do with putting in a new OEM Toyota evaporative charcoal canister? Could my ECM/PCM/ECU (whatever you want to call it) be going bad? That was one of the things that came up in researching it when receiving random codes.

Otherwise the truck seems to be running just fine.

 

Did you have to unplug anything to get to it and maybe didn’t plug it back in all the way or accidentally disconnected a vacuum line

 

This!

 

I don't believe so. On my truck the canister is behind the gas tank. It's 4 bolts, 1 wire connection, and the 2 vent lines for fuel vapors. I've double checked all of them. The codes I'm getting are really random. Especially like the heater control circuit, camshaft sensor failure, and O2 sensors switched between banks codes.

I did just run to my local Oreilly and Autozone stores and used their scanners (2 different brands/types) and neither of theirs picked up any codes. So now I'm wondering if it isn't my el-cheapo bluetooth dongle that I use to connect to the Torque app?

 

I'm not familiar with the vent lines on the canister but is it possible you mixed them up when putting them back on? Just a thought.....maybe it wouldn't make any difference but....

 

No, that's not the case. The two vent lines are different sizes so it is a pretty foolproof swap. Although now I'm really starting to question the accuracy of my code reader. It's just a ELM327 bluetooth dongle that plugs into the OBD2 port and then that connects to the Torque app. Like I said above, neither of my 2 autoparts stores readers showed any codes while mine does...maybe all of this random code stuff is just faulty readings on my end? I do have an appointment with the dealer on tuesday and in the meantime I'm going to double check my air filter, clean my MAF sensor. Maybe I'll get lucky and the loss in fuel efficiency is as simple as that?

 

I rarely trust car parts off Amazon even if they say it’s from a dealer. They are well known for selling cheap Chinese knock-off, especially their spark plugs.

 

Very true on Amazon. When shopping around, I compared prices between Amazon, rock auto, etc. and they were all within $20-40 of each other. I opted for the Amazon one just to save $30 (cost plus shipping) and faster delivery. It shipped from a Toyota Dealer from Atlanta and came in a Toyota box with all the applicable info. While it is certainly possible they are packing cheap knock-offs into OEM boxes and shipping them out I guess I'm not too worried about that. Believe me, I've received my fare share of cheap crap off of amazon, but those all came from no-name manufacturers and associated packaging so I'm fairly confident that this particular part is genuine.

Either way, I opted to go the DIY route as my dealer quoted me over $1100 to put a new evaporative canister in. While I have no qualms over them making a profit on stuff, the ~$600 profit seemed a little dis-proportionate for (4) 12mm bolts and (3) connections which took me a grand total of 30 minutes to install lying on my back under my truck.

 

Did this get fixed? Having the same issue
