Passat (B5) :: Check Engine Stays On Majority Of The Time - Evap System?
Aug 21, 2012
i have a b.5.5 V6 4motion and My check engine stays on the majority of the time. I've had a tech check the code and he tells me its my Evap system. The same tech told me that it was actually pretty useless to repair the problem unless the check engine light bothers me..

So, I have a 2009 IV, and it has about 60,000 miles on it. It's still has it's Toyota Certified warranty.
The check engine light has been going on and off for about 3 months. I hooked up my scan tool, and it says there were a bunch of codes popping up for the evap system. I did the obvious repair and replaced the gas cap (with a Toyota cap), and that worked for a few weeks, but the light came on again.
Since it's under warranty, I took it to the dealer and it turns out the vaccum switch (or maybe pump) for the charcoal canister was bad.
Struck me as a rather strange thing to go bad on a relatively newer Prius.
Anyway, had the water pump recall done while it was there, and hopefully all is good now.

So mad today. Check engine light came on, plugged in my scanner, got P0441 EVAP Emission Control system Purge Flow Fault and P0455 EVAP Emission Control System Leak (Large).
8-month old '13 TCH XLE is getting a check engine light already.

My check engine light came on the other day, with no symptoms or problems. Today I stopped at the Auto Parts store and had the codes read. They were P0440, P0441, P0446, and P0301. They are for the EVAP system and misfire.
I had read here that one of the codes could be for the gas cap so I tightened it and then, also as read on here, disconnected the negative 12 V battery cable to perhaps clear the check engine light. I was curious.
When I started the car again, I now have not only the check engine light, but the red triangle exclamation point. How would you proceed? The 12 volt battery is around 5 years old. The entire exhaust system was replaced last year.(not O2 sensors though)
The hybrid battery was replaced at 70,000 miles and I now have 110,000 miles on it. I really wonder why disconnecting the battery and reconnecting it caused more error lights to appear? Also, the Auto parts guy said his code reader was fine for my car but I seem to remember here that there may be a special Prius one.

I only have 2200 miles on my new 2012 Passat SE V6 and the check engine light came on the other morning. I took it in to the dealer and they found codes P0442 (EVAP Emission Control System Small Leak Detected) and P0456 (EVAP Emission Control System Very Small Leak Detected). The tech says on the work order that he removed and tested the EVAP Purge Valve with a vacuum pump and the valve would not hold a vacuum. The dealer replaced the EVAP Purge Valve under warranty. They say this is the first 2012 passat V6 they've seen with this issue. I've only had the car for 4 weeks.

I have a 2000 B5 . It has minor damage front and rear (cosmetic only). Also, the check engine light stays on due to a vacuum leak somewhere between the MAF and the intake manifold. It would need a full paint job at some point after the body work was completed.

2003 passat GLS stock w/ 1.8T, MIL comes on after full tank drops to about 3/4 full. Code 16826 will clear but keeps coming back, always when the tank is about 3/4. I have replaced gas cap but, no luck. Also, sometimes after filling the tank the light goes off by it's self.

New owner of a 2003 1.8TPassat (29,000mi) as of the last 2 weeks and have just had my MIL come on. Scanned it at home with my Actron CP9125 scanner and got this code (P0455) which reads in the scanners manual as "EVAP Emission Control System Leak (Large)". Didn't know if this was a generic description of the code or VW has a more specific definition. What precisely this is in reference to, gas cap, vacuum hose????? Or what VW's actual description of this code is?

My 97 Passats CEL stays on all the time. The shop I took it to told me that the computer was bad. I bought a new one and now the engine won't turn over. What could be a possible issue?

CEL light stays on for a few days, then will go off for a few, and vise versa. car doesn't run rough, but sometimes doesn't want to crank. can the purge valve cause that, and could it cause a misfire code? and how can i disconnect it, or what can i do to see if it will make a difference without the purge valve connected and working? BTW, what is a purge valve?

I recently had some work done on my 2001 1.8t Passat. All new vacuum hoses & camshaft tensioner replaced by VW dealer. Check engine light is coming on and an independent shop near read out a code: Bank 1 mixture adaptation(multi): System too lean.
What does this mean??? And could this relate to these parts being replaced??? Work was done approx 2000 miles ago.

Encountered this check engine problem > 16805 and 16815 < I replaced the 02 sensors, problem solved for 1000 kms, and now the dreaded light is showing its face again ! Possible secondary air system at fault? Cat about to go, or already gone?

After only 1k miles after purchase my Check Engine light as come on. P0440 and one other (left the paper at work)
I haven't overfilled on Gas, the Gas Cap is completely on (2 clicks), and I haven't OVERLY pushed the car either haha.
The only update was replacing the STOCK filter with K&N Drop In Filter.

I've had a check engine light on in my 3.5 Pontiac G6 for awhile now. It's an emission code (can't remember what code but evap leak). The solenoid by canister was also tripping a code that disappeared after I changed it. However, the evap code still persists. Last night while changing my oil I noticed the intake air hose to the crankcase had broke at the case and wasn't connected. It's the hose that runs from the engine intake to the crankcase for the PCV system.
I am replacing the hose regardless, but my question is; would the intake hose for the PCV system being loose cause an evap leak code? I am thinking no but it'd be nice if it was that simple.

I have a 2005 1.8 TJetta GLI owned for about 2 months now. Gas cap warning pops up then goes away when I turn off the car then check engine light comes on. I've change the gas cap to new oem one changed the purge valve [URL] .... After a couple of weeks same issues again brought it to my mechanic he ran a leak detector and told me that there are Evap leaks. I read somewhere that I might need a need charcoal canister and a fuel tank.

We have a 2003 Passat 1.8t. Had the Check engine Light come on. Went down to AutoZone and hookeded up the OBDII reader. Came up with P0171, Fuel System for Bank 1 was too lean. Probable causes:
1. Fuel Pressure of MAF (If Bank 1 & Bank 2 set codes together)
2. O2 Sensor
3. Ignition Misfire
4. Fuel Injector Problem
Car has 60K - has always run well. Wife says she thinks it's running a bit sluggish. I rarely drive the car, but I think she's right. Car is not missing or running rough.
I cleared the code & started the engine; Check Engine Light is off; then looked at the codes and I find a P0171 (Pending). She tells me that the light has been on before & then gone away. So I guess it clears itself, but eventually comes back.

Engine runs perfectly but "check engine" light" stays on due to faulty Emission Evap control pressure sensor (P/N; 89460-0w020). Problem is Toyota no longer makes this part and there is no after market for it. It appears I may have to "junk" a perfectly good truck.

I had a check engine light cane on. I took it for it to get checked and they gave me this code- P0457 EVAP small leak detected. ECM has detected a large leak in the EVAP System during a system monitor test.
The paper said I had a leak in the Evap canister or hose. I took the truck to a mechanic and was told I had Bad oxygen sensors. Can Bad/Dirty oxygen sensors make this error code come up?
Exactly where the oxygen sensors are? I was told they were behind the mufflers but I didn't see any and the diagram I found was not accurate.

I bought a 2007 Lexus LS 460 L recently and the check AFS (Adaptive Front-lighting System) at dealer light is coming from yesterday which was rainy, and I also noticed that the APGS (Advanced Parking Guidance System) was not working also , and if I leave the car off and come back after several hours light seems to go back off and on again after a while. I just changed the tires a week ago.
I would think it would be a sensor but is there any sensor that is used for APGS and AFS as they both stop working at the same time, give me messages to take to the dealer.
* NO data controller
* NO air suspension on the car
* All original parts
