ECM and O2 Sensor Codes (P0606, P2195)

Good morning all,

I was on my way to hike Mt. Princeton and the CEL came on - living the dream.

I know this is not a mystery but I would really like to hear if anyone else has had these codes pop up at the same time. I'm a little worried about doing one portion of the work before I'm able to do all of it because I'm guessing one might be causing the other.

The first code I'm getting is the P0606 code which has to do with the ECM - which I'm hoping isn't failing but is likely failing, knowing my luck.
- Two fixes I've found per BlueDriver include Replaced ECM entirely or Repair ECM Connector.

The second code is P2195 which has to do with an O2 sensor on bank 1 that is reading stuck lean.
- There were 9 suggested repairs for this code- see attached image.

I did a search of the forum but the closest result that came back was P0607 on the second gen Tundra portion of the forum.

Any input would be greatly appreciated.

(Full disclosure- The weather is amazing- was roughly 71 degrees with no rain or water present in the air or otherwise when this came on. I did drive through a puddle that was on the road not too long ago but didn't seem like there was anything out of the ordinary after that.)

PS. Does anyone know where to find replacement speakers or have a suggestion for a cheap brand that works well with the factory setup- I'm sure anyone reading this will laugh at me for still having a factory sound system.

Thanks again, all - you guys have been great.

 

First off. Clear the codes. See if they come back. I know it sounds stupid, but I've had a knock sensor code throw twice since I've owned the truck, truck goes into limp mode each time, I clear the codes, all goes back to normal. The codes were separated by months, if not a year. Sometimes flukes happen with electronics.

In this case, if P0606 comes back, getting a new ECM isn't that hard or expensive. fs1inc.com sells re-flashed units for your vehicle. You just need to pop out your glovebox and get the part number off the sticker on your ECU. It'll be in the format of XXXXX-XXXXX where any of those X could be letters or numbers.

Nobody is going to laugh at you for having stock speakers. I actually shipped all my OEM stuff - OEM amp, head unit, and my OEM speakers to different members who wanted to stick with OEM or revert back to it. That said, you've given us grossly little info on your Double Cab's setup to know how to help.

Please read the "Audio, audio upgrades and cameras..." section of this thread, and when you can tell us more about your setup - i.e. if JBL, and if not JBL is it amplified? - and we should be able to help: https://www.tundras.com/threads/so-you-wanna-buy-just-bought-a-1st-gen-tundra-eh.115928/

 

This is the amplified JBL system. I will check out those links, thank you! Guess I neglected to inform you guys of that because it was secondary to those CEL’s.

thank you!
