How do you replace the oxygen sensor 1 in a 2001 toyota tundra V-8. Where can I look for a diagram from a auto manual on the internet for multiple vehicle models?
What code did you get?
The tester showed it was Sensor #1. That’s why I put sensor 1 in my question!
I know it’s sensor one, but does it say what bank?
Also, providing the actual code you got can help the techs here diagnose your problem better. How did you decide the O2 sensor needs replacing? A code won’t say the sensor is bad.
