I need help with this

1. I need help i changed both my check valve and pumps on my 2012 4.6 toyota tundra and the codes never went away sick with p2438 how do I test the check valve they're aftermarket. I know the pumps work tested them already
2. Codes that popped up
3. 2441,2443,2447,2438

 

Did you ever clear them?? If you don't have an obd 2, you can always pull the negative terminal 30 seconds and reconnect it and see of they come back at all

 

Yes a cleared them and them pop back up

 

They may be bad to begin with. They may need further troubleshooting though. Maybe a damaged wire or ground.

 

I put the old ones on and same code but I could clear them and they wouldn't come back on unless I restarted the truck

 

Sounds like they're bad out of the box, or the wrong units.

 

I think so I put the old ones back on got rid of p2438 now just have the 2441,2443,2447
