Question about 2004 Chevrolet Silverado 1500 Crew Cab

2 Answers

My truck has had problem with the check engine light recently. about a year ago the light popped up and it was the evap system. the dealership said i needed to change the gas cap, so i let them do it and the light was fine. then about three weeks ago the same light and same code came up and the dealership said it was the selinoid and i gave them the ok to fix it which cost me just under $300. now the same light came back the other day and they are telling me that i "need to have the hose from purge valve to seal line" and this was quoted at a price of $182. now my question is basically are they not diagnosing my problem correctly or is this bad luck? and is $182 a reasonable price for this repair? Also is the purge valve different from the selinoid that was fixed 3 weeks ago?

This can be one of the harder problems to fix so it will stay fixed. The most common problems I see are dirt filled Vent valves, [especially if you live on gravel roads] leaky purge solenoids, plugged charcoal cannisters, loose gas caps, cracked plastic lines OR a combination of all of them which can make you want to pull your hair out. Another problem is that this system doesn't run a self test all that often so it's hard to tell if it's really fixed for a few days or even a week or more as it has to fail a couple of self tests before it will kick the light back on. I don't think they're messing with you but I'll bet they'll give you a pretty good break if you ask them since you seem to have been pretty good about the problem so far. Good luck with your problem!

2005 Chevy Malibu evap sensor won't go off after changing it. Recently had a fuel level system done on the tank.


evap sensor won't go off ? Do you mean the check engine light ? What DTC - diagnostic trouble code ? fuel leveler system done ,your funny ! Fuel gauge sending unit of fuel pump ? With the fuel nozzle shutting off like that, the air in the tank is causing that , which means there is a problem with the Evap vent solenoid or wiring to the vent solenoid .

Where is evap emission


Your evap emission system is your pressurized fuel system. If you are getting a check engine light and the scan is throwing an evap code start by changing your fuel cap. It is the cheapest part of the system and quite common to fail. Unfortunately if you change your cap and erase your fault codes and the check engine light returns for evap system again, you will probably end up at the dealership to track down the leak.

What does the code PO455 mean?


PO455 Evap System Gross Leak

The old days left in 1981 some 32 years ago

You really have to smoke test the Evap System to
find hose leaks & use a scan tool to actuate the solenoids
to check for bad ones

Without a system diagram your pretty much lost

While driving i see the oxygen sonsor light comes on any ideas what to do?


Check the PCM for trouble codes. Once you know what code is present post it and we will have a much better idea of what is wrong. Also post a year, model and engine size. My best guess since you recently had the fuel down dropped is that there is an issue with the EVAP system. Possibly the seal for the fuel pump. Or maybe a EVAP line was left off or has come loose. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

The check engine light on my 98 saturn sl1 came on a few weeks ago. i went to go get it checked and i got "p0446 evap emission control, system vent control circuit malfunction" as a result back....


no , not really expensive. yes it can be fixed by replacing the vent solenoid. the solenoid (usually open) gets stuck and the computer can shut it to run the EVAP monitor so it sets the code.

My 98 MGM check engine light came on and II had it checked and it turned out to be the gas cap. I replaced the gas cap and all was well for about 6 weeks. then two days ago the check engine light came on...


emission problems are common, there is a evap canister underneath near the tank. also sensor built onto it. sometimes water get into there especially seeing the year they crack. its best to go to a tech who expeience with th evap system.

My check engine light came on my car about a year ago and I got a code - P0497 Evap Emission purge flow fault. I had my check engine light reset. It has now come back on again. Do you think it's the same...


You have to pull the codes, do not guess, waaaaay too expensive...THe purge system bleeds tank fumes into the intake system, for clean burning.... Something (was at least) is worng, pull the codes and proceed.

Leak in evap system, where and what is an evap system. 2001 mitsubishi Galant


I have the same failure that occurred when smogging my Ford Ranger. The EVAP test was just added a couple of years ago and it tests for leaks in the gas tank vapor recovery system. What this is a system of vapor recovery lines that connect from the gas tank and goes to a canister then returns to the intake and on the next engine start and gets used, instead of leaking into the air.

The only issue is these lines can develop a leak at any of the connection points or along the rubber portions and can be a pain to replace depending on your application. So until you fix the leak you will fail this test since they pressurize the system and if there is a leak it won't hold the pressure.

Diagnostic code P0456 for 2003 Dodge Ram 1500 5.7


P0456 = EVAP Emissions Control System Leak Very Small

Is the gas cap on tight or is the seal damaged? If it needs replacement, get it from the dealer.
