HI,

Ok, this is for Bank1(rear bank) catalytic converter. You need to check for exhaust leaks and repair as found. If ok, then the rear back catalytic converter will need to be replaced - see attached directions

One problem you may run into is snapping off the studs when trying to remove the nuts for converter as well as snapping off the bolts for it due to heat corrosion. If this happens, then you can be looking at removing the cylinder head to have the broken bolts extracted.

If for any reason, you can't rate my answer OKAY, GOOD, or EXCELLENT/3 STARS OR HIGHER today. Please reply and let me know why, so I can help more/better. All follow up responses are FREE, after completing the required rating

The light goes off once a year for a couple of days. Do you think using a catalytic converter cleaner/gas additive may work enough pass inspection?

HI,

You can try cataclean and see if it will turn the light off long enough to pass inspection. It works about 50% of the time. Most major parts stores carry it

Thank you for your reply but I am going to try a catalytic converter cleaner first if it does not work then I will probably take it to a mechanic.

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

Linda B.USA

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

Wonderful service, prompt, efficient, and accurate. Couldn't have asked for more. I cannot thank you enough for your help.

Mary C.Freshfield, Liverpool, UK

This expert is wonderful. They truly know what they are talking about, and they actually care about you. They really helped put my nerves at ease. Thank you so much!!!!
