I have had evap solenoid problems on a fiew cars and the answer is yes. It is model specific. However, there are several possable causes. Usually the"gas cap problem" isn't a bad gas cap at all. The common gas cap issue is you put gas in while the car was still

Lets start with how knowledgeable you are

You have an EVAP System issue,maybe

You asked if the gas cap is specific

You know that it is to some extent
Application Specific -but the parts store
would give you the correct one

Was the first code even related to a gas cap?

When you say I was told, you mean what?

A professional mechanic you asked a question,
took a guess to give you an answer?

Do you know how to test the solenoid your
referring to? If not take it to a repair shop &
let them Smoke Test it & actuate all the system
components with a scan tool.

One suggestion I have is that each of the new type of engine's have an O2 sensor which is part of the exhaust. This is used by the computer to measure the amount of O2 in the exhaust gasses in the exhaust.

Go to the parts store where you bought the cap. Sometimes the code clears on it's own and sometimes you need to have it reset. If this is not an option disconnect the negative battery cable for a minute. Just as a warning, if you disconnect the battery you will have to reprogram most all of your electronics.

Check engine light


you were told your vehicle has small/large evap leak detected? The leak could be coming from any number of components. Fuel tank seal, evap purge valve, check valve. The best way is to find the leak with a smoke machine. It is designed to find leaks in the evap system. There is a port with a green cap in the engine compartment. This is where the hose from the machine attaches to. Turn machine on. Where ever you see smoke, this is where the leak is.

Service engine soon light is on- 2003 BMW


The p0455 code means, Evaporative Emission Control System Leak Detected (no purge flow or large leak)
After you install the new gas cap, reset the code, dirve the car for a couple of days to see if the code comes back, if it comes back there might be a leak in your evap lines.

Check engine light keeps coming on replaced gas cap already


Your problem is in the evaporative emission system which is designed to prevent the escape of fuel vapors from the fuel system. Leaks in the system, even small ones, can allow fuel vapors to escape into the atmosphere. The light coming on can be caused by one of the following:

1. Defective or loose fuel cap
2. EVAP canister or hose cracked- not connected
3. Purge or vent solenoid defective
4. Vacuum leak at engine Government regulations require on-board testing to make sure that the evaporative (EVAP) system is functioning properly. The leak detection system tests for EVAP system leaks and blockage. It also performs self-diagnostics. You have tried the easy fix, the gas cap. Finding the leak now will require special equipment and testing procedures, might be better left to a professional.

Please let me know if this information is helpful. Positive feedback is appreciated. Thank You!
