Mechanic for Honda: MASTER TECH, Honda Technician replied 2 years ago

thank you

now this P0401 is caused by a restricted egr flow and the intake upper plenum will need to be removed and cleaned out, in order to perform some basic testing to confirm this and update the pcm you will need to have the Honda scanner to perform this task

now your battery light is whats flashing ?

here is the egr update kit that we were installing years ago but you can still purchase the parts in the kit form but will still need to drill the intake out as described in the bulletin.

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!!!!
