P2238 02 Sensor 5.7 Tundra (1 Viewer)

Looks like I need to replace the upstream bank 1 o2 sensor.
Just double checking with the mudborg if there is anything else that could throw this code?

It's been very cold. I'm also thinking possible crud build up on the sensor...

It looks like we will be back above freezing in a couple of days. Clear the code and take the wife for lunch in Penticton and give it a good run coming back up the hill. I recommend The Hooded Merganser.

If the code comes back, at least you’ll have a full belly when you tackle it!

Update - Suspect short trips in extreme cold caused the codes. It warmer now and the code hasn't returned.

may be worthwhile to unplug and check for corrosion in the plug

Will do.
