Customer Question

I have a 03 Toyota 4runner Sr5 4.0 V6 I replaced the upstream o2 sensors and now have a P2241 code for low positive current on bank 2 sensor 1. The sensor is the recommended Bosch sensor and I did not have this code before changing the sensor. I checked the a/f heater fuse it is fine. this is my only vehicle and is required to pass nys inspection in the next few days and I am at a loss with this problem

hello and welcome, bank 2 two is on the driver's side, is this the one you replaced, what code were you getting before replacing the sensor?
