Quick question. Well I...

Quick question. Well I hope so :) Both the cabin air filter and the air filter found under the hood can both affect the emission engine light?

Mechanic's Assistant: Has your vehicle stalled? Has anyone run a diagnostic test to pull the trouble code?

No to all those questions. I'm not trying to "solve" this right now. But those need to be changed and before I take it to the dealer I'd like them handled. Just wondering if they are related

Mechanic's Assistant: What is the model/year of your Honda?

2016 pilot

Mechanic's Assistant: Are you fixing your Pilot yourself? What have you tried so far?

Nothing so far. Light just came on. But we haven't changed any air filters since we bought it. So I want to at least do that. We are out of warranty so anything I can do ahead of time would be best for us

Thanks for holding!
The cabin air filter is not monitored in any way by any on-board computer system. If this filter is dirty it cannot set the emissions light. The engine air filter "can" IF it is excessively dirty. However, more times than not, this is usually not the case. If the emissions light is on, then there is a problem in the "EVAP" System. Unfortunately, there are literally dozens of parts and sensors in the EVAP system and to take a guess as to which is faulty would be impossible. The next course of action here is to have the Diagnostic Trouble Codes (aka "P-Codes") scanned from the on-board computer. You can have these p-codes read FREE (except in California) at any local "big chain" part store (ie. AutoZone, O'Reilly's, Advanced, etc). These p-codes will more accurately point to the part or sensor that has the problem and from there, the correct repair can be made.

Sorry one more thing if possible? The code is P403 - could I ride this out until next Monday? The car at the moment runs fine. We are moving this week and time is a problem.Thanks

Please hold one moment while I type out some info for you...

Ask Your Own Honda Question

The P0403 is pointing to a problem in the EGR (exhaust gas recirculation) System. There are a few different items that will need to be tested in the system to find out which has the fault. In the meantime, it is "safe" to drive the vehicle. However, you "may" notice a bit of power loss and/or lower fuel economy.

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

Mary C.Freshfield, Liverpool, UK
