Ford Ranger / B-Series :: Check Engine Light Came On - Code P0457 EVAP Small Leak Detected?
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.

View 3 RepliesPontiac :: Check Engine Light On / Evap Leak Code?
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.
Golf IV / Jetta IV :: Check Engine Light Comes On - Code P0456 For Evap Leak
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.

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.

View 5 RepliesFord F-150 (2009-2014) :: Check Engine Light Came On - Small Evaporative Leak Code
I have a 2009 ford f150 4.6l 3v v8 standard cab with about 53k miles on it.
Recently the check engine light came on so i went to autozone to have the codes pulled for free, it says i have a small evaporative leak.
They said may be the gas cap, but the thing is, i have a quick fill cap that came in stock with truck so the gas cap isnt even needed.
I've looked under the hood, and noticed that there is little pool of oil on top of the valley of the engine on the passenger side of the engine, could it possibly be the PCV hose that is bad and be related to the evaporative leak code? or its unrelated and i have a bad gasket for the valve cover?
It isn't affecting the performance of the engine,.. yet. I have a road trip for my work coming up very soon and i wanted to try to fix it before then.
Toyota - Corolla :: 2009 - Check Engine And VSC Off Lights On / Gasket Starting To Leak
I have a 2009 Corolla with 48,000 miles. Yesterday night, the check engine and vsc off lights came on. By the way, a gasket is starting to leak (probably unrelated to the lights).
How urgent are the lights? Can I wait to get the car into an independent dealer next Tuesday?
Toyota - Corolla :: Getting Check Engine Light?
This is a California car that won't pass smog tests with a lit check engine light. I don't know the specific code, but the description is that the torque converter is staying in the "off" position. Apparently the lock up torque converter is part of the emissions system in that if the torque converter does not lock up then the rpm's are higher and that produces more pollutants.
1st step was to flush out the transmission and the flush made sure all the fluid in the torque converter was removed and replaced. After that was done the trans fluid has stayed nice and clean and pink for about 400 miles. The CEL was turned off after this service but came back on in a few days at about 200 miles. Next, the solenoid that activates the torque converter was replaced. The CEL was turned off again, an this time the CEL came back on after a hour of driving on local errands.
Me and my generally good mechanic are hung up now. We were betting the solenoid change out would solve the problem. It seems that the torque converter is in fact operating properly. The tranny shifts smoothly and the rpm's drop at the proper times indicating the torque converter is locking up.
Toyota - Corolla :: Check Engine Light Came On A Day After Getting Gas
At a service station in NJ, my gas cap flew into the wind and the attendant replaced it. My check engine light came on a day after getting gas (not in NJ) so I took it in to my garage. Ends up that the (new) gas cap has a crack and a new one is getting ordered. Now, whenever I am filling up the gas tank, it keeps shutting itself off (very frequently . . . like every 1/2 gallon or so). This happened when the check engine light was on and after it was initially turned off by the mechanic. I asked a mechanic at the garage because it keeps happening and I can't fill the car fully and he said it happens with some cars and you have to hold it a certain way or something. This can't be fixed and I'll just have to get used to it until I get a new car. My question -- how could this have just started happening? Its a 2002 Corolla and I've had it for years without problems. Is it possible that when I get a new gas cap and the computer gets re-started, it will fix itself?

My girlfriend's 2001 Toyota Corolla has a recurrent Check Engine light problem. It has 144,000 miles on it. For the last few years, we have been unable to keep the light turned off. We have replaced the oxygen sensors and cleaned the MAF sensor. Our mechanic can't find the problem.
View 3 RepliesToyota - Corolla :: 2004 - Check Engine Light Was On Then Went Off After A Day
I have a 2004 Toyota Corolla.
Check engine light was on so I took the car to Midas they pulled a code (133) and they said its Oxygen Sensor is not working. I took the car to Auto Zone for second opinion, Auto zone confirmed that Oxygen Sensor might be having problem. Then I inquire in couple of places for the price to fix O2 sensor, all most all places I got the same quote to fix it.And after a day or so check engine light went off. Check engine light was on for a day or so.
Now I am confused, is there a problem with Oxygen sensors? Should I still go ahead and fix these sensor or should I wait till Check engine light comes back again?
Intrigue :: Code P0442 - Small EVAP Leak
So I have had this code P0442 for a long time and I just kept clearing it. The attached picture (at an angle) shows the hole in the small line attached to the fuel neck filler exactly behind where the plastic wheel well cover touches it. Just ordered a new one from rockauto for about 65 shipped.
View 5 RepliesGolf IV / Jetta IV :: CEL Code For EVAP - Very Small Leak
Got a CEL tonight while driving. Originally I was driving and the light came on saying that my gas cap was loose. I corrected the problem when I got home and tightened again. The light stayed on however. I ran a scan with the OBDII and it gave me a code for EVAP- Very Small Leak .
I was reading around and some people suggested the MAF. Which would make sense because I recently had all of that stuff off and gave the engine a deep cleaning while it was exposed. I just don't see how the MAF could relate to the code my car is pushing?
Toyota - Corolla :: Check Engine Light Comes On And Goes Off (PO125 And PO441)
For a few months, I have been getting check engine lights on my Toyota Corolla 2002. The check engine light often goes away by itself.
I took my car to a mechanic with a decent reputation after a couple weeks of the problem. He thought he fixed it and gave the car back to me. The check engine light kept coming back on, and I kept going back. The mechanic topped off the coolant, replaced certain hoses, host clamps, sensors and other parts (like the solenoid canister). After the fifth trip back (and eight weeks of time), he refunded my money.
The check engine light comes on and goes off. Right now with no check engine light on, I get codes P0125 and PO441 PD.
What will happen if I keep ignoring these check engine lights or the codes that persist when the check engine light is not on? I was thinking of going to another mechanic. I think I want to wait for a few more weeks to see if I notice a pattern. I do not drive that many miles each day (much less than average).
Toyota - Corolla :: 2002 - Flashing Check Engine Light?
I have a 2002 Toyota Corolla CE with about 115,000 miles.While I was traveling on the highway my car started shaking, losing power, and the check engine light started flashing. I drove a mile or two to a rest area because I didn't want to pull over on the highway. I had it towed home. It starts and idles, but I'm afraid to get it out on the road.
View 15 RepliesToyota - Corolla :: 2002 - Check Engine Light Came On After Oil Change
Had the oil changed today; before doing so, I saw that the check engine light had come on. Have been told by 3 professional car maintenance people that there is no connection between needing oil / oil change and check engine, that it would have been the check maintenance light.
Will take it in for diagnostic test by dealer. Also, was told by the oil change guy that he heard pinging which could mean that the car needs to have the valves adjusted, and that the check engine light is due to needing something or other with the gas tank filter which could have a leak/crack, etc.
Toyota - Corolla :: 2006 - Check Engine Light Comes On When Cold?
The check-engine light on my 2006 Toyota Corolla came on a couple of weeks ago after I started the car on a 7-degree F morning. Code was P-0171. Mechanic cleaned the MAF and the light went off. Light stayed off 'til I started the car on another 7-degree F morning. Mechanic said that the MAF didn't look dirty, and the readings didn't change after cleaning. No vacuum leaks. O2 sensors responding normally. What's going on? I travel a lot in this car, so I don't want to damage the car by ignoring the check-engine light.
