Exhaust valve mod

[B16B]

Hi guys,

Just wondering if anyone has ever checked or knows if pulling the fuse for the exhaust valve sets any sort of hard or soft stored fault codes?

Thanks

sorry, I haven't checked so I don't know.
since we're now here... why are you concerned about whether a fault code gets saved?
I promise you, dealer = DGAF
I laughed because I think you're overthinking it... enjoy your car bro!

That was my exact thoughts. I just didn't want the give the dealer any sort of BS reason. Ive had bad experience with BMW warranty in the past with a blown engine so I'm not sure how Honda is as far as their warranty claims and how strict they are.

Honda is the #1 engine manufacturer on the planet. I have confidence that if the engine in our car blows up, it is very unlikely to be caused by a fuse that was pulled out.

In contrast, if it were a BMW, if we pulled an exhaust fuse out, I bet the car wouldn't even start.

This is relevant to many owners because any codes (even pending) will disable some of the fun Hondata exhaust features that many have grown to love.

To my knowledge I've never seen anyone report an issue due to this but It's not something I've tested myself.

Yes it does store a code. I can't remember correctly if the code was P-16B or P-16E. It was something along those lines, that fuse is part of a communication line.

You pull the fuse but put it back after making the valve move to the open position.

Really? I thought the fuse has to be completely removed for the valve to stay open and if you reinstall the fuse it goes back to the normal operation?

Mine threw a code P16EB.

I first pulled the fuse but with the connector in place. Later I modified the exhaust and so the connector is no longer plugged in. It took a while but threw the code. Autozone couldn't read it or reset it. Honda didn't like the modification and told me that the car will be out of warranty if I don't put it back to stock. He also said if it's tuned, I'll void the warranty. They reset the code for no charge.

There is a plug in that is on Amazon and Ebay that supposedly makes it look like the valve is connected and working. I wonder if it is effective? Has anyone here tried one of these?

OP - Dealers won't specifically look for it even if it stored a code for the fuse pulled. I had been into the dealer 3 different time for various stuffs. Not once did they mentioned anything about my fuse issue on my exhaust. Each time doing their standard multi-point inspection - not sure if scanning the car is part of this multi-point inspection.

Dealers don't normally do diagnostic checks unless there's a CEL, a pending software update(or TSB), it's been requested by the owner or a part of the maintenance minder schedule services. Most dealerships also don't really care too much about the P-16 code because all it means is that the ECU hasn't received a signal from the exhaust valve when it did the systems check.
