When you say won't go over 20, do you mean that it tries and loses power? Does the vehicle rev high or back fire while pressing the gas?

​​The codes that you have are for the knock sensor and the catalytic convertor. A couple of things could be going on here. Your catalytic convertor could be clogged(P0420) and preventing the vehicle from creating power. In order to determine this, the pressure coming from the tailpipe will need to be measured. If the pressure is reduced, or not there, then the catalytic convertor will need to be replaced. Also, the knock sensor(P0325) is producing a code that may result from a misfire in the vehicle and will also cause reduced power. I would first check the converter to see if the exhaust is breathing properly as this is the most probable cause.

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
