Prius (Gen 2) :: Check Engine Light Has Been Going On And Off - Evap System?
Jul 13, 2013
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.

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.

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.

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..

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 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'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.

The engine check light is ON this morning. It said that there are problems for the hybrid system on the display. I sent it to dealer immediately.

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.

Just found out I have a problem with my evap system (97 Grand Prix GTP). My SES light comes on intermittently. Not sure what the number of the code is, but my mechanic said it was because the vacuum was too strong (not a leak). He said could be from a kink or clogged hose. What this could be? Are the hoses and canister easily accessible for me to check?

So a little over a month ago, I was driving my 2010 Prius (about 42k miles) when the Check Hybrid System light came on. I lost power and my car was stuck on the road, as I was unable to get it into neutral. So I called a tow truck and was towed to my local dealership. The dealership ran some tests, thought it might have been the throttle body. They switched my throttle body with a loaner prius to see if this fixed the problem. The new throttle body worked in my car and my throttle body was put into the loaner and functioned fine. Then they ended up fixing a TSB for the electronics in the car. I was told the problem was resolved and I could pick up the car about a week later.
After picking up the car a week later, before I could even drive away from the dealership, the Check Hybrid System warning came on again. I talked with the service manager and left my car to be fixed again. They checked all the systems and were still unsure what the problem was. Eventually they made sure all the connectors were properly seated and test drove the car and ensured the problem was gone. About two weeks later, I was told the car was fixed and I could pick it up.
After picking up the car, I was still unsure the problem was fixed, but I was told that was all I could do. After having the car, for about a 1.5 weeks I was on the highway. Once again, the check hybrid system light came on and I lost engine power. Luckily, I was able to pull over from the left lane without causing an accident. Once again, I had the car towed to the dealer and now I am waiting to hear back from them.

I just bought a used 2012 Toyota Prius iTech from a country town 3 hours away. About an hour into the drive home, the display informed me to "Check Hybrid System" and then "Check PCS System". The car continued to function for a little while, then eventually lost acceleration, so I pulled over. I turned it off and on again; the warning light remained but the car started and continued to work, but soon after I lost acceleration again. This happened one more time.
Then I Googled the problem and discovered that you could "turn it off and on again three times to reset the computer". I did this and the problem disappeared and did not resurface for the remainder of the trip, and has not happened again since.

I ran out of gas in my 2011 Prius and immediately all warning lights came on as well as the "check hybrid system" light. After filling the gas I read similar threads on here and trouble shooted the battery. 12v Battery tested good, so now what is the next step? I also did a reset on the 12v battery and that didn't work.

I have a 2013 Prius Persona with about 5,300 miles on the vehicle. Just recently had the 5,000 mile service taken care of at a local toyota dealership. The very next day I tried to start my vehicle with no prevail. My instrument panel indicates "check hybrid system" (!) the car will not start, nor will it shift into drive or reverse, only into the neutral position. Made several attempts to turn vehicle on and off and tried to jump start. Still no luck. Had the car towed back to the dealership. Mechanics are still trying to identify the problem. What may be the cause?

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?
