Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is ***** ***** thank you for your question.
What codes number are you getting and what year and model Nissan is this?
Is this a 4 cylinder or V6?
The front 02 sensor is not really a 02 sensor. It's called a Air Fuel Ratio Sensor. It's like a 02 sensor but the connector is very different.
So I am assuming this is a 4 cylinder and you wanted to just replace them both?
Is this the same exact code you had before the two sensors were installed? Did they clear the codes after they installed the sensors?
Just trying to get some history on your issue. The reason is because some times when the 02 sensors are removed, they can get seized to the exhaust manifold. When this happens the threads can get damaged. If the sensor is just threaded in when the threads are damaged, it could not seal properly which allows outside air into the exhaust which can cause this code.
Other wise, it could be that it is a after market electrical part and that is not operating to specification. When ever it comes to electrical parts, after market are known not to work 80% of the time. Where when you get parts from the dealer, they work properly 90%. So I would double check the 02 sensors to verify there is no leak. If no leak, then you most likely got bum sensor from Auto Zone, which is not uncommon.
Do you have any more questions on this?
I understand that. Did you read what I typed about after market electrical parts?
You never told me that they did not clear the code. I asked you that but did not get a reply on that.
Do you want to clear the code yourself and see if it returns?
This is the most detail I have gotten from you on this issue. I did not know they did not clear the code.
" Hi my name is Gayle
I received my code from Auto Zone and they sold me 2 oxygen sensors. I took them to Midas to have them installed "
To Clear the codes yourself, disconnect the negative battery cable for 15 mins. This will erase all radio pre-sets and clock. But will clear the code.
If you have remote start let me know before disconnecting the battery.
