Nissan Repair Questions? Ask a Mechanic for Answers ASAP
It is very possible an exhaust leak could be the cause, But first I want to ask, What brand of Sensor did you put back into the car? Also, did you check the fuse?
It is located in the fuse box under the hood. I attached a wire diagram, It is fuse number 8 which is a 15a fuse. Also, I would stick with a factory sensor, these cars are VERY picky. At the shops I run, we NEVER use any aftermarket oxygen sensors as they have proven to not be reliable at all.Check the fuse, and if that is good, the next step is to make sure the driver in the ECU is working, which we can do with a test light.
Thanks and let me know about the fuse!
