Hey guys

I have had my hchii for 90k miles now and still love the car
I have gotten my first check engine light, that I can not
figure the reason for.

I did a search for code p16n5 and could not find what that means,
has anyone gotten it or know what it means? I did also get with it po420
for the cat below threshold bank 1.

I have a Ultraguage reader, and after I booked the appt with dealer soon the light went out. The reader still has the codes stored. By the way the check engine light went out by it self.

Any information good or bad would be helpful...I like to go to the dealer with as much information as I can...so I can tell if I am getting the run around.

I still have the HondaCare warranty with the car so anything should be covered

Thanks

Its possible the gas cap was not tightened? One day I pulled a plug apart on top of the engine and reconnected it. Check engine light was on for a few days after that. H

 

That was my first check, however I had already put 400 miles on the car...so
little chance of that, and it was tight
