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.

2002 Ford Ranger XLT v6 extra cab.

Camry :: OBD Code P0442 - Small Leak In Evaporative Emission Control System

Got an engine light on today and had it checked at Advance Auto. It is P0442, "small leak in Evaporative emission control system". One article I read said to remove and retighten the gas cap, clear the code then see if it occurs again. If it does then replace the gas cap with a new OEM cap, and try clearing the code again to see what happens, as a first step in the troubleshooting process. I retightened the gas cap, but don't know how to clear the code and turn off the engine light.

Chevrolet - Equinox :: Check Engine Light Is On For Evaporative Emission System Leak Detected

I have a 2008 Chevy Equinox, and recently I noticed a gas smell...I saw Chevy had a special policy to replace the fuel pump module, so I took it to the dealership hoping that would be the problem. Fortunately it was, and they replaced it for free. I got my car back Thursday afternoon, drove it Friday, and it sat yesterday without being driven. This morning I drove to the grocery store, and on the way home my check engine light came on. I have an ODBII scanner, so I plugged it in and got this code:

P0455: Evaporative Emission System Leak Detected (gross leak/no flow)

So I was wondering: (1) what is the cause and/or solution to this problem, and (2) is it possible the dealership caused this problem when they replaced my fuel pump module?

It seems awfully coincidental not to be related to the repair, since it is a fuel system problem, but I don't know enough about cars to be sure...

Ford F-150 (2009-2014) :: Check Engine Light Came On While Towing - Code P0299

He has a 2013 F-150 XLT with the Ecoboost. He has 29,000 miles on the truck.

He is ~1,300 miles into his trip; and has about another 4,500 to go! On Friday, his check engine light came on (while towing). The next day it went back off. Yesterday, the light came back on (while not towing this time). He took the truck into a Ford Dealer in Rapid City, SD this morning. The CEL light was still on this morning when he arrived at the dealership. The dealership said the code is P0299 - Turbo Underboost.

They said they've run tests and can find nothing wrong. Naturally, he is not very happy being this far from home with 3 more weeks of vacation left and his truck acting up. Especially since the CEL light is on but the dealer can find nothing wrong. I'd be puckered-up too!

Experienced this Turbo Underboost condition? What was the cause? How can the CEL light be on but the dealership not be able to find a problem?

Ford F-150 (2009-2014) :: Intermittent Check Engine Light Due To Same Code Every Time - P0171

For the last few months my truck has been throwing an intermittent check engine light due to the same code every time - P0171. The dealer has allegedly checked everything and has given me the "We have done all we can do" speech. Lead tech even suggested that since today's fuels have alcohol in them, that a check engine light would be normal. The truck has been in the shop 3 times with no success or even remote possibility of what the problem could be.

The check engine light has since gone from intermittent to constant and comes back on after 5 drive cycles after clearing with an OBD2 scanner. Also, I'm now getting a P0174 code.

Personally, I think they're trying to blow me off because I'm a few months and about 2k miles away from being out of CPO warranty.

Truck is a 2013 F150 Super crew 2wd 5.0 with about 45k miles.

Mitsubishi - Lancer :: CEL Is On For Evaporative Emission System Very Small Leak

I have a 2006 Mitsubishi Lancer and CEL is on, I got the code checked and its showing P0456 ("Evaporative emission system very small leak"). They recommended that I replace the gas cap, but I already tried that without luck. I have heard that the tubes in the system go bad and need replacing. I know some are located behind the back wheel but I wanted to give the ones under the hood a visual inspection so I have some clue when I take it for a repair.

My trouble is that I don't know what tubes I'm looking at! But I have some pictures, so at least we have that!

So the first one is zoomed out of the engine (obvious right?), just so you can see where everything is going. The hose I'm suspect of is the one that's to the left of the motor oil cap, the one I'm holding in the second picture. If you can see it, there's a split running down for about 6" -10"

What I'd like to know is did I assume right that this is (at least one) of the hoses causing my trouble with the evap system? And if it's not, which ones should I be checking out?

Mazda :: 2004 - Engine Code Reading P2402 - Evaporative System Leak High Discharge

I have had issues for over a week now first problem check engine light not sure of the code but the mechanic said it was the spark plugs and vaccum leak hose (which I knew about the hose). $205.00 later replaced all 6 plugs and hose. Now today on way to work I'm getting that hesitation when in lower gear such as stopping and then accelerating it jerks some it was doing this alot before replacing the plugs.

We did a diagnostic code reader and it said the code P2402 I did read it could be my gas cap which I don't have a dealer gas cap on there now I did about 1 yr 1/2 ago but got a lock key gas cap instead. I have been doing some reading I would need to replace leak detection pump which apparently costly in repair.

BTW car has 119,000 miles I commute far from work 5 days a week. My car is very important part of my life! I did also read someone stated there was a recall on Mazda 6 wondering do I need to call the dealership to see if this is actual recall and I can cross my fingers get this fixed on them.

Ford F-150 (2009-2014) :: 2013 - Check Engine Code P0355 / Cylinder 5 Coil Malfunction

I have a 2013 F150 6.2L and it wont start. It was running great and when I drove it around the corner it just shut down no clunk no warning just bam shut off. I had a engine code P0355 ( which indicated cylinder 5 coil malfunction). changed the coil and it will not fire the engine code has gone away but it will still not fire. I changed the oil just to be safe and no metal shavings in it.... Turns over just fine but will not fire. I added more fuel just to be safe ( thinking maybe I had bad fuel but that didn't work either.

Ford F-150 (2009-2014) :: 2010 5.4L 3V - Check Engine Light On

2010 F-150 5.4L 3V gas, 6 speed auto, 2WD.

I got a Bully Dog GT Platinum Gas with plans to purchase a tune from 5starturning. Was messing around and loaded the built in 05-10 Ford Gas tune in Bully Dog... all went well.

Take it for a drive around and next thing I see is my check engine light is on so back to the house and revert back to the factory file... again, all went well.

No such luck; still have the check engine light and the Bully Dog says there are no DTC codes. Needless to say, I'm a bit freaked out.

I have tried uninstalling the Bully Dog tune and reverting to factory file and still no luck.

I think I would feel better about it if I could just find some comment saying "this is common just unhook the battery and reset and go on your merry way".

Ford F-150 (2009-2014) :: Check Engine Light Intermittently Comes And Goes

Purchased certified pre owned 2009 f150 may/2010 24,000 mile. The check engine light intermittently comes and goes. It seems that its either cold temperature or related to filling the gas tank. The first time it appeared I drove 100 mile then the truck sat over the weekend and went back off when started. The second time had serviced for the check light and the dealer diagnostic pin pointed P0304, P0305, P0300 and P0316 and replaced cyl 4&5 coils.

Prior to the replacement of the coils the truck averaged 18.2 mpg since the repair the mpg dropped to 17.6 and now at 17.2mpg. Had the truck in again and the light was on when I made the appointment but went back off when I went to the dealer. They said the reset the computer. The light twice has since went on and then back off after a couple days. The only observation is that the outside temperature on both occurrences has been below freezing and that I had filled up the tank.

Santa Fe (CM - 2007-12) :: 2009 - Small Leak EVAP Code P0456

2009 santa fe 67000 miles. Replaced fuel senders approx a month ago. All was fine. On about the 3rd fill up the cel came on. Code was for small leak evap. checked the gas cap, no problems. Replaced the purge valve and disconnected the battery while doing so. Cel light went off and stayed off thru one tank of gas. Filled up again and thought I detected a little fuel smell shortly after and cel came on again. I only smell fuel when its full and down to just before 3/4's. The light came on right before 3/4's. My husband is beyond frustrated and wants to smash the car lol. Once I get him calmed down where should we be looking for a leak and how to fix it? We can't afford a dealership bill right now and of course it's due for inspection next month.

Code was p0456

The only answer I got in the DIY section is to check around the fuel senders again but I'm leery to do it as I can't see how there would be a leak there, the covers go on SO hard even with that tool.

Ford F-150 (2009-2014) :: Truck Running Bad And Check Engine Light Came On

After about 5 miles from my normal place to purchase fuel, My truck bagan to run bad and the check engine light kicked on. Mileage dropped to about 8 MPG. This morning, the truck would not start and after 2 can's of dry gas, I was able to start it (barely).

I stopped at the place where I purchased fuel and at least they admitted that they has to shut down yesterday, stating they received a bad batch of fuel from their source.

Now the fun begins...How do I get the "bad gas" out of my truck?. I now have about 1/4th of a tank. I tried to run a line to siphon the gas and I can not get a line far enough into the tank.

Ford F-150 (2009-2014) :: 2011 - Shuddering - Check Engine Light Flashed On

2011 eb just turned 36k. Today on breezeway it shuddered like it swallowed a bird, and check engine light flashed on. Went to see customer left and light was off. Back on breezeway and shuddered on entrance ramp so this time I stayed into it so either there's a light that will stay on or just launch it and this time the dealer will have something to fix that they can diagnose. Check engine light is on its fine as long as I stay out of the pedal. Still have 8 months left on power train warranty but what am I looking at for a diagnose, there is definitely a problem now. What the dealership should see?

Ford F-150 (2009-2014) :: Check Engine Light And Limp Home Mode

Truck: 2009 F-150 Lariat SCrew 5.4 4x4 with 6.5" bed

For the last few years, I've had this intermittent problem where the service engine light (wrench icon) will pop on and the truck will go into limp home mode. While it's in this mode, all of the indicators on the dash freak out. Low fuel warning will come on, temperature warning, low battery voltage, etc. Turning the truck off and back on (sometimes a couple times) is enough to get it back to normal, albeit with a check engine light that needs to be cleared. It's happened infrequent enough that I've just been dealing with it. I got the codes a couple years back, but there wasn't much information available on what the potential causes might be. The Checker Auto parts database suggested one might be related to a wheel speed sensor.

Well, this afternoon it happened again, and I was near an O'Reilly, so I took it in to pull the codes. There were 9 total in the system; 5 of which were unique:

B0025
B00D5
U0073
U0100
U0253

They didn't have any information on what was causing them. What could be causing this. I'm getting sick of having to clear the check engine light and worry about the truck falling into limp home mode when I'm at intersections.

Pontiac :: 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.

Ford F-150 - 1997-2003 :: CEL Code P0455 - Large Leak Detected In Evaporative Emission Control System

I own a 98 f-150 5.4 with 70,000 miles. I get a check engine light (code p0455-large leak detected in evaporative emission control system).

Replaced the gas cap with an after market 'stant' ( I believe was the manufacturer) brand. The check engine light went away for 4 days then came on again.

No obvious vacuum line leaks.... Puzzled.
