- Background -
- The car: 58,000 miles
- No engine modifications.
- Drive the car 3 days a week to work, 120 miles round trip = 360 miles/week
- Use Shell 91 Octane - Last fill up, the gas/fuel pump didn't shut off and some of the fuel came out and split over.
- Drove 100 - 120 miles no problem/no check engine light.
- Yesterday, turned on the car, drove for 2 mintes, check engine light came on.

This morning I took my nifty Innova 3100 OBDII Code Reader, checked my car for codes and came back with the following:

P1457 Evaporative Emissions (EVAP) Control System Leakage (EVAP Canister System)

I looked over my Helms Manual...which directed me to pages 11-146 through 11-151. Yikes!!!

Someone please help me out...hopefully there is a simple solution.

If not, I guess I have to go to the Acura dealership in town...and I am not really looking forward to that since my wife just spent a nice chunk of change on a haircut, perfume, skirts, etc...bleh!

Anyway...if anyone can please help me out, it would be greatly appreciated!

EDIT: The car still gets awesome mileage...anywhere from 35 - 37 m.p.g. weekly.

Same thing happened to my 95 GS-R. I actually overfilled my teg with Hi-Octane Gas as well and it started acting a little crazy! The next day the engine light came on. I went in and checked my code book and found the same problem as you. Then I went in myself to check all my internals personally with my friend. We found nothing. I got back into the car and reset my ECU. It has been running fine and that has been about 5 months ago.
(To reset ECU there is a button under the dash by your right knee if you where driving locate it! Turn your key to second slot with battery running and hold that button down until the light goes off. If this light continues to come on I recommend going to the acura dealer.)

I believe the button under the dash, right near my knee as you mention, is the button that will reset the "maintenance required" light. That button does not reset the Check Engine light.

Thanks for your help though.

Make up some wire so you can energize the valve directly from the battery. I found that to be easier than messing with the ECU plugs. It'll let you check the valve but you still might have to check the wiring to the ECU.

I guess a MityVac, a nice DMM, & some stuff to make up jumper wires should be on your shopping list.

 

Thanks for your help. I really appreciate it. I was hoping it wouldn't be as involving as the manual goes into.

I would love to try to take care of it, but I don't have the tools on hand, garage space is very limited, and just getting off a 12-hour graveyard shift doesn't help either.

Thanks again though. I really appreciate your quick response.

 

My friend told me that button resets the entire ECU correct me if im wrong how do you reset the entire ECU?

 

If you pull the ECU back up fuse (7.5) from the fuse box under the hood on the passenger side of the engine compartment it does. The one under the dash only kills the "maintenence req" light. I am having evap (code 90) problems too but I never top off. I let the pump do it. I am thinking tho, as some people posted, its the gas cap. its just annoying. I can understand having mods and a "change engine light" but a completely stock GSR is bugging the hell out of me.

 

Ok, here's an update.

Cleared the "Check Engine" light with my Innova 3100 OBDII Code Reader. Drove around hoping that the check engine light would come back on. It didn't. Realized that the "P1457 Evaporative Emissions (EVAP) Control System Leakage (EVAP Canister System)" code/check engine light will come on when the car is...well read on.

After doing some research, it seems that the P1457/EVAP Canister System takes fuel vapors from the fuel tank on initial start up...when the engine is cold... and slowly releases the vapors back into the engine, as the engine warms up during driving. Thus the system prevents fuel vapor from being released into the atmosphere.

So my feeble attempts at getting the check engine light to reappear by driving around for awhile, while the engine was hot, was a lost cause.

So I headed home, filled the car with gas, and put the car in the garage.

Made an appointment with the Acura dealership tomorrow. Get this...$98 for them just to run a diagnostic on the car. The service represenative told me that their computer does a lot more than just tell them the code. Somehow that made my stomach un-easy...because he just had to tell me that. What was the point? $98 to plug my car in a freaking computer and tell them what the problem is...how lame. I know what it is!!! Code P1457!!!

I feel like I am being OWNED by Honda...or Acura as they like to call it here in North America.

$98 for a computer diagnostic.
Most likely $2.00 plastic piece or hose that has a hole in it.
Me = Owned


Anyway...does enyone have any info on whether this should be covered under emissions warranty? I have a feeling that it should be covered since the car is barely 4 years old. Should I somehow bring this up to the service represenative when I take the car in tomorrow?

 

good god its as easy as diconnecting the battery for a few minutes. that will definetly reset it!!

 

It could be a disconnected hose, but it could be a shot solenoid valve that takes an hour to change. Or maybe a pressure sensor that you have to drop the gas tank...

The EVAP canister 'stores' the evaporating gasoline during the entire time the car's parked. When the engine's running, it sucks a little air thru the canister to burn that fuel. That's how it works, but that's not what triggers the CEL.

Every once in awhile, the ECU closes some valves & watches a pressure sensor. This is while the engine's running. If the system isn't airtight, the pressure won't change. The whole reason for the extra valves & sensor, is so the ECU can tell whether the system is still working OK. When I had a bad vent-shut valve, I could reset it & it wouldn't come back for a couple days. It wasn't about hot or cold, I just had to wait enough starting/driving cycles.

 

just reset the ecu.. you either have a bad gas cap or it wasnt tightened all the way.. go to honda, buy a new cap and clear the code..

on your way you go.
