P1150 Toyota - 2000 Avalon

Question

just bought a 2000 Avalon, has a o2 sensor code bank one, I was told that was the front bank, should I replace the o2 and see if the p1150 comes back? or is it a diferent problem in the back bank?

Answer 1

Hi there

Normally the O2 sensor is the cause of the issue, however I believe this is a code for the bank 2 upstream sensor. The only way to be 100% sure is to use a scan tool that can watch the sensors.
