Our trusty '01 Tundra 4.7 with 209K threw a P0135 trouble code. O2 Sensor, bank 1 upstream.
Amazon sent me the Denso for $47 all in, next day delivery. Easy peasy install and cleared the code.
These engines are real smoothies and ask for very little. But suck the freakin' gas!
Man she purrs even better now. Hopefully it improves the mileage if it was running in open loop before.
I was wondering if it makes sense to replace both upstream sensors?
