Ford - Explorer :: 2005 - Emission System Won't Working - HC At 102 Ppm?
Jan 4, 2013
I have a 2005 Explorer Sport Trac 4.0L V6 that fails emissions for high HC at idle. I have already replaced upstrem and downstream 02 sensors, air filter, gas cap, EGR module and PCV valve. OBD II reader shows no DTC's and green light shows indicating all emission systems are working. The initial test showed HC at 102 ppm, for which the Calif. standard is<100ppm. Also seems to have a smell of unburnt fuel. After all the repairs above HC actually went UP to 147.

I had my alternator and battery die on me in Dec 2015 and replaced both. Vehicle ran perfectly fine until this Sept 2016. First thing to happen was the battery light came on and then the System Charging Failure message and the tone came on and off intermittently. I took it to my garage and they tested and said the alternator was defective that they replaced in Dec 2015. It was showing 9V.
So they replaced it again free of charge with another rebuilt alternator. Within 30 min leaving the garage the system charging failure light was back on and again i lost charge to the point where everything was shutting down to the point i even lost the gauge cluster. Took it back to the garage and they checked the plug at the alternator and said it was fine. Then they said the belt was loose.
So they replaced the belt, the belt tentioner, and a pulley. Within 20 min the lights were all back on again and I was losing charge and all the things started to shutdown again. Where I picked up the car at 5PM on a Friday they had left and wont be back till Monday. So I am asking here....what is going on??? What else is there to look at or replace to fix this charging error???

Check Charging System message, battery-shaped idiot light, and audible beep has happened a few times over the past month or so. Yesterday it happened while my wife was driving so I had to bring it to the dealer, not to mention I drove it last night and there was constant beeping for about a minute which was pretty annoying.
But first I had the battery checked, which turned out to be OK. Also we got a new alternator 5 months ago, installed by the dealer.
Today they said they "updated the computer" whatever that means, and otherwise couldn't find anything wrong. $99.85 plus tax.
Needless to say I'm not confident that "updating the computer" has fixed it. What are the odds we get the warning again in a couple of weeks? Short of disconnecting the sensor, is there anything that can be done?

Three weeks ago I replaced my battery and serpentine belt as general maintenance before heading out on a prolonged trip. The next day I started receiving 'check charging system' whenever I turned the a/c on and the truck is at idle. Power steering becomes very hard to turn and engine feels like it is going to quit.
This is not a problem at highway speeds. Looking at the engine when the a/c is engaged, a slow down of the belt/pulley is obvious. The alternator has been removed and checked, battery checked good, and the belt is the right size/length. What could be causing this? Again it started behaving like this after a belt and battery change. There is no issue if the a/c is off...

Just replaced the tires and wheels on my 2005 EB Explorer. Purchased a set of Better aluminum wheels and tires on Craigslist. Problem is old ones had TPMS and new ones don't. I will put the sensors on the new wheels when the tires wear out, but don't feel like the expense until I need new tires. Is there an easy way to turn the system off so I don't get the message every time I start the vehicle?

So my car's emission systems light came on last Saturday and after work today I took it to the local Auto Zone to have an onboard diagnostic done to see what the code was, as some friends had recommended. I have a 2004 Ford Taurus with about 146,000 miles on it. It came back as only one code, P0456, which according to the clerk meant one of four things.
1.) Defective, loose, or missing fuel cap
2.) EVAP Canister Broke, hose cracked or not connected
3.) Purge or vent solenoid defective
4.) Vacuum leak at engine
I asked him if there was anyway to eliminate a few of these, but he wasn't sure and said I would have to take it to a dealer or a repair shop (which I expected). I was wondering any tips or tricks so I can eliminate a couple of these, and also if this is a five alarm fire I should be panicking about. I did call my Dad and he did not seem overly concerned about it. Plus my car is still running fine and the light has remained steady and not flashing. My friend at work suggested I put a piece of black electrical tape over it and ignore it, but I want to be sure it passes inspection in September.

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.

2009 Impala, 50000 miles, runs good, however service engine light is on with a DTC showing P0455, "Evaporative Emission System Leak Detected, Gross Leak/No Flow". Are there obvious things I should search out or has there been a common problem in the EVAP system on this make and model that would pinpoint the leak?

I have some codes on my ranger 2000 here goes
P0141: o2 sensor heater circuit malfonction (bank 2 sensor 2 )
P0455: evaporative emission control system detected (large leak)
Now I will need to get that fixed cause I don't know where to look and what to look for ... For the leak I know there is a big crack on the plastic where the gas lid is could that be it ?

I have a 2005 Ford Escape 3.0L V6. The emission systems/check engine light keeps coming on. I have taken it to 4 different places and the diagnostic keeps referring to the MAP Sensor. It has been replaced twice (granted one was free) and the light is still on. I have also replaced a coil, the plugs and boots.

We are selling the girlfriends 01 Passat. I pulled the codes tonight for a long standing check engine light knowing it had one of the 02 sensors bad. Here are the three codes I received from the scanner:
P0130 - 02 Sensor Circuit Malfunction (Bank I Sensor 1)
P0455 - Evaporative emission control leak detected (large)
P0441 Evaporative Emission Control System Incorrect Purge Flow
So is it one thing causing all three or are there common things to look at. We can't really afford to go replacing all the emission system sensors and hoses etc. in hopes of finding the right piece. Gas cap is screwed on tight and codes were cleared a couple times to make sure.

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?

I just changed the drain valve on the fuel filter bowl. All went well and no more leak, but now I am getting an "emission system" warning light.
After I replaced the valve, I filled the fuel bowl with diesel fuel. Was there any other priming that needed to be done (if any)? What the emission system warning light may mean?

2008 with 165K. I had the fuel pump replaced then started getting this code. Garage said they did a smoke test could not find any leak. I then replaced this part (CCV #31453-3K500 / picture attached) I still get the code.

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?

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.

The check engine light on my 99 Camry went on at about 180,000 miles. My mechanic checked the code and turned up an EVAPORATIVE EMISSION CONTROL SYSTEM INCORRECT PURGE FLOW He said this could be any number of things,including the need for a gas cannister or some type of valve. What does this mean? How do you determine exactly what the cause of the problem is? What are the likely fixes? Will Toyota be able to better determine the cause than my personal mechanic? What are the best options?

I am getting the dreaded emission workshop.
The codes i am getting are p0301-p0304 and p0171
Which are misfire on 4 cylinders and system to lean (bank 1).
Here is what I have done:
Got the 4 ignition coils replace, replaced the mass air flow, replaced the air filter, replace the plugs.
I just check the L wire and it doesn't have any cracks or holes
I don't know what to do next.

Just received a P0441 CEL (Evap Emission System Incorrect Purge Flow). I have a 2.7l engine, 2WD. I've read other forums and it seems it's most likely the purge valve or charcoal canister.
