Hyundai Repair Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for using Just AnswerI'm Paul and I will help you with your Question
what is the fault code you are getting with the light?
I took it to Advance Auto and I don't remember the exact code but they said it was the bank one oxygen sensor. When we replaced it I took it back becasue the light came on again even though I had taken it off the battery to clear the light. So he cleared the light with the the computer and said if it happens again take it to a mechanic!
Certain oxygen sensor codes are set do to lean conditions like vacuum leaks etc.
because the code references an oxygen sensor does not always mean the sensor is bad.
if the light does come back get the exact code and I can further help you
a vacuum leak can set oxygen sensor codes also
Ok I won't be able to do thatq until tomorrow how do I contact you again?
just login to the site
and go into your question.
I will be around after 1pm eastern tomorrow
ok reply when you get more info
bank 1 sensor 1 is at the firewall (windshield) side of the engine . the connector is under the throttle body
is this the sensor that was changed?
they changed the wrong sensor
the sensor on the front manifold near the fan is bank 2 sensor 1
bank 1 sensor 1 is on the back side near the firewall the connector is under the throttle body
the sensor itself is under the vehicle
How many oxygen sensors are on this thing? I am looking at the part number they gave us online. Denso(NNN) NNN-NNNNand it Upstream left and right, they also show a Downstream left and right with a different part number. Could tey have given us the right part but told us the wrong place to install? It doesn't show bank 1 or 2 on the discription of these part numbers.
its an upstream sensor right bank (firewall bank)
the sensor is underneith as shown in the picture I attached
the connector is under the throttle body
there are 4 sensors on this vehicle
it is very common for v6 cars to have 4 sensors this is not an unusall situation
they just changed the wrong one
Ok I found it. I'm sorry to be so persistant, but the one I changed before was on the pass side up front. What s that one called? and are they all interchangable? I hate to keep asking stupid questions, but I don't want to buy another one if I don't have to since I saved the last one I changed. Now I see the wire length is different. The one I need has a longer wire on it than the one they gave me.
the one you changed by the fan
was upstream left bank 2 sensor 1
if the part number for both upstream sensors is the same then it will work
the bank 1 sensor 1 shown in the image I attached is also an upstream sensor
I am attaching the image again you get it from under the vehicle the conector is near the throttle body.
no problem thank you for using Just Answer
