ACURA 3.2 TL 122500 MILES

1999 All Other Makes All Other Models

Forgot to mention that here in PA. In order to pass the emmission inspection (smog test) the gas cap must be tested. I would assume this to be true around the country. Any location requiring smog testing should have test facilities, either private or state, that can test your cap.

Might be cheaper and less trouble just to order one tho. : )

I have got an Acura 3.2TL, works and performs perfectly. But there is a little problem that I have, " check engine" light is lit up. I took it to the Acura dealer they said the cat converter needs to be replaced. I have gotten the cat converter replaced as well as the O2 sensors. After reseting the check engine light it still remains lit up. The transmission was replaced back in October 2005 and now that operates just fine.I have taken it to the dealer again and they say that the computer code indicates the " Gas tank vaccume". What is that and how can I fix it to get rid of this check engine light?

Autozone stores will pull codes free of charge. Post back with the exact code. It has something to do with an emmision control reffered to as the EVAP system. This system includes several items, the gas cap, solenoids, vents, sensors, etc. There are also 15 or more seperate codes if memory serves.

Good luck and let us know. : )

P1457 Leak Detected In EVAP Control Sys.(EVAP Canister Sys.) (Acura)

I'm not personally familiar with acura only codes. Generic OBDII codes that are similiar are PO440 thru PO455. They narrow the field of possible offending componenets down considerably.

The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.

The most common leak is a loose gas cap. Also refueling while the engine is running can set this code. If there are no driveability issues I would remove the gas cap and reinstall it. Then reset the codes and see if it returns.

A gas cap is pretty high tech nowadays. It is both a vent and a pressure release valve. I have had one fail and had to simply replace it to solve a PO442 code.

The next step would be to inspect the canister, tubes, and hoses for leaks or damage. A hole as small as 1/16th is enoiugh to set a code for a small leak.

After that the valves and vents would be suspect. Not to common tho.

Try the cap and let us know. Good luck. : )
