I did not know this I only purchased 1 are they both the same thing and where are they located
Mechanic for Honda: Ron Z., - Honda Tech - replied 7 years ago

 

They are not the same and not interchangable. I would strongly recommend you find out which one needs to be replaced, as installing the wrong sensor will cause problems. And replacing the wrong sensor will get expensive. I can give you locations, and the procedure is the same for both, but like I say, find out for sure which one is faulty. One is located in the exhaust manifold under hood, the other in the exhaust pipe under the vehicle.

  • If "sensor2" raise and support the vehcile
  • For both: disconnect the electrical connector
  • Remove the oxygen sensor.

I just heard from my mechanic. You were right...a $45.00 job. THANK YOU!! Your response was received in less than 10 minutes!!

Your answers were clear and the diagrams were perfect. Dealer wanted $87 for an hour of labor and even I did it in 15 minutes.

EdUSA

HONDA PLATINUM was great. I really appreciate his help. I was ready to trade my new Honda until he told me to wait until I got 3,000 miles on it and my gas mileage would get much better.

SummerUSA

I took the Power Steering O-Ring service bulletin linked from JustAnswer to my Acura dealer, and not only did they no-charge the o-ring, they also replaced the power steering pump at no cost.

Gary RStevenson Ranch, CA
