Hondacamp :

What year and what engine? P1259 is Vtec oil pressure malfunction. Check the oil level. Often times caused by low engine oil. P0420 is Catalyst Deterioration. You will need to replace your Catalytic Converter most likely. P1738 is 2nd Clutch Pressure switch circuit. Most likely a faulty pressure switch in your transmission.

Thank you very much for saving my daughter and her family a lot of money on her Honda. You are definitely on my list for future help. Thanks, again.

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!!!!
