A few weeks ago according to the CEL code: my O2 sensor bank 2 sensor 1 needed to be replaced. I did with a

Toyota sensor. Now the CEL light is on (after around 1,500 miles) and I get 4 codes: P0032, P0038, P0052, and P0058

If you replaced the B2S1 with the correct Denso unit, then chances are the rest are going to need to be replaced as well. It's the nature of the Tundra ECU.

Interesting that you had all four go off at the same time for the heater malfunction. What have you done mechanically and/or fuel-related in the last 4-5 days?

I replaced B2S1, and have done nothing but drive the car a fill it up. I travel all over, but try to get brand name fuel: Pilot, Mobil, Sunoco or Valero around 99% at the time. I am confused, since the sensor I just replaced also comes up.

The fact that they're ALL throwing the same code is a little suspicious to me and leads me to believe that it is something else, i.e. induction and/or ECU-related.

Let's start here: Clean the MAF (and the throttle body if you can...), pull the negative cable on your battery and let it sit for about an hour. Reconnect and drive it around a bit to see if the codes get thrown again. We'll go from there.

Friend of mine has the lates SNAPON code reader, he checked the codes (even went in thru the "back door" where Toyota goes in), he also reset the computer. Far as the sensors, in August I did an upper intake SeaFoam treatment, cleaned the MAF sensor, wiped the throttle body clean. Then put in new iridium plugs, new air filter. The truck runs just great, even with the light on it gets 17-18 mpg. What I am doing next is as soon as the light comes on I will have the code(s) check. I was away from home and it took me 3 days to get it read. I am a maintenance "fanatic" I do it at 80%, I never wait unitl it is time to do it, I do it way before. Wondering if some kind of electrical signal is messing with the puter, I have 2 CB's, a polica scanner, light bar control box, cell phone charger, inverter and bunch of othe things in there, however they have been there for years so not sure what is going on.

When the first sendos went it had a p0051 code (low heater)....... all the codes now are pointing to the high heater on all the sensors.
