Question about Ford Fusion

My EGR tube burned a hole in the wiring harness of my 2010 Ford Fusion is this a design flaw

Engine light and picture of a wrench came on. Took car to dealership. They said the EGR tube burned a hole in the wiring harness. Is this common? 3yr warranty had just expired. Extended Warranty refused the claim. They appealed and it was overturned. Warranty is covering the cost less my decduible. Is this a design flaw or what?

I have never heard of this problem on this model, but it would likely be caused by excessive exhaust system back pressure due to a possible faulty catalytic converter broken catalyst ceramic brick.

This problem sounds like ablown head gasket, this would make the oil mix in with the gas and would result in discolored smoke out of the exhaust pipe.

SOURCE: 2003 Toyota Camry Se V6 has a check engine light

I had the same problem, then took my car to an expert repair shop who diagnosed the sensors and
found no problem with the car. They notified the DMV who was unaware of the problem, who then told the repair shop (John's Bascom Automotive) that they will adjust their computer system to allow a "two speed idle test". My bill was $95 and I still have to pay for a smog test after driving around for
a couple of days to clear the computer monitors, a fair amount and I gladly paid it.

John advised me that I'd get no satisfaction with Toyota or the DMV. I went to the dealership where I
bought the car and they said that the smog stations don't know what they're doing. They charge
about $100 and work around the P0500 code but it takes them about two hours to do this. I told
them that I should have been notified about the dyno none-compatability by Toyota and that Toyota
should have notified the DMV beforehand. I wonder how many speed sensors are being replaced by
unknowing smog shops around the state. I got Toyota's main customer support phone number and
will call them Monday. I'm going to get my pound of flesh ($95 worth) from the DMV next week also.

I have had a reoccurring problem with my right signal light burning out I told the dealership that I thought it was a short. just the other day I took it in to get it fixed again and the very next day...

you just have a bad socket. The parts dept can get just a socket. Usually what happens is the gnd tab in the socket gets pushed in and instead of completing the gnd it arcs it and then kills the bulb.

Egr valve troubleshooting

Hi Mike, I'm glad to help! Mike in the older cars like your we've found here at the dealership the most common problem is the EGR causes a vacuum leak and the engine dies at idle. Here's how you can check it. Warm the engine to operating temperature, let it idle while taking a can of carb-cleaner or parts cleaner and spray it directly into the opening of the EGR Valve. If the engine trys to die then replace the EGR Valve. NOTE: Be sure to clean the tubes and holes that are related to the EGR. CAUTION: When using the cleaner to check the engine be careful not to overdue it and cause a fire because the cleaner is flamable. I suggest having water or fire ext handy just in case, I've never had a problem but its always good to be save then sorry. Hope this helps and have an awesome day Mike.

Replace egr valve on 3.5 litre 215ci v6 how to?

  • Disconnect the car battery. Locate the EGR valve. You may need to refer to the owner's manual.
  • 2 Unhook the air supply hose, vacuum hose and all electrical connections. You may need the screwdriver for this.
  • 3 Remove the EGR mounting bolts with the socket wrench.
  • 4 Unbolt the EGR valve from the EGR tube with the wrench. Use a wide-mouthed wrench, which works best for this.
  • 5 Look at the EGR valve. If there are holes in the valve, it definitely needs to be replaced. If there are no holes, you may opt to clean it by spraying a half can of carburetor cleaner into the valve. Let it sit, then use a gasket scraper, putty knife, small drill bit or long wood screw to scrape out the buildup in the valve.
  • 6 Install a new gasket and EGR valve if a total replacement is due. Attach all hoses, wiring and bolts that were previously removed.
  • 7 Reconnect the battery and test drive the car.

  • if this helps you please give a good thumbs up rateing thanks have good day

    Picture of egr valve and were it is located


    Fig. 11: EGR valve and component mounting-3.0L engine


    Fig. 12: EGR valve and component mounting-3.8L engine

    1. Disconnect the negative battery cable.
    2. If necessary, remove the air inlet tube from the throttle body and air cleaner housing.
    3. Label and detach all vacuum hoses from the EGR valve.
    4. Label and detach any electrical wiring harness connectors from the EGR valve.
    5. Disconnect the EGR valve-to-exhaust manifold tube from the EGR valve.
    6. Remove the EGR valve mounting fasteners, then separate the valve from the upper intake manifold.
    7. Remove and discard the old EGR valve gasket, and clean the gasket mating surfaces on the valve and the intake manifold.
    To install:
    1. Install the EGR valve, along with a new gasket, on the upper intake manifold, then install and tighten the mounting bolts to 15-22 ft. lbs. (20-30 Nm) on 3.8L engines, or to 106-159 inch lbs. (12-18 Nm) on 5.0L engines.
    2. Connect the EGR valve-to-exhaust manifold tube to the valve, then tighten the tube nut to 30 ft. lbs. (41 Nm).
    3. Connect all wiring or hoses to the EGR valve.
    4. Install the air inlet tube.
    5. Connect the negative battery cable.

    Hope this helps (remember comment and rated this).

    I have a code of lowair flow egr valve and have changed to valve and cleaned the throttle body housing with cleaner. servie engine light still comes on with the same default but not all the time.

    Hello! This is a somewhat common issue where there is an excessive buildup of carbon in the EGR port in the upper intake manifold.
    This is the EGR Valve as removed from the engine:

    On your vehicle, you will notice that the flexible tubes are held in place by one bolt each. If you remove these tubes from the engine side only - you will be able to clean inside the port that they connect to. I have had good luck using a parts cleaner that any Chrysler dealership sells - it makes short work of carbon build up. Once you have the ports cleaned out - reassemble the EGR tubes to the intake. Be sure to get them seated fully before you tighten them back down.

    Hope this helps and good luck!

    Its not the EGR tube that's clogged. Its the intake itself, where EGR bolts to it. There is about a 1/2 inch hole that cloggs and needs to be cleaned out.

    Difficulty to replace EGR valve in 1999 totyota camry 4-cyl automatic

    Not difficult at all to service the EGR Valve using a #12 mm socket wrench it is a five minutes job. However the VSV is another history and very difficult to be reached unless you have an elevator After the engine begin stalling I double checked the EGR which was completely carbonized. I cleaned it and also replaced IAC checked VSV and all sensors, but the engine follows stalling. Now I am looking for the Charcoal Canister which I simply can't find where it is located, then I will check the vacuum lines and the transmission sensors, but I have heard that EGR despite cleaned can keep bringing troubles. By the way, anyone has ever heard where in the car is installed the charcoal canister
