2004 Honda Accord goes into limp home mode in cold weather

I am having a problem with my 2004 Honda Accord Sport 2.2 Diesel- here is my issue-- in cold conditions the heater plug light flashes continuously and the engine looses power allowing only revs up to and under 2000- it goes into limp home mode. I brought it too my mechanic who did a reading on it in mild weather and could find no fault it appears that anything above 5 Degrees C- yesterday at -3C the heater plug light flashed and performance slowed again then when going up a hill the car began to chung slightly then the engine management light came on and the car died. After about 5-10 mins I was able to start the car and drive very slowly to the garage. Can you give me any insite as to what might be wrong please

Hi
Any number of things can throw you into limp mode and you definately won't have vtec. Most likely if you have a CEL fix that first then worry about VTEC. CEL can be a great indicator as to whats going on, and that light is lit for a reason. even when people say, "I have a CEL but thats a different issue" ,fix that FIRST, then worry about vtec. many codes that are set have alot to do with why vtec isn't working. If your car is not acting right take apart the dash and check that your CEL light is not burnt out. it should light up when you first turn the key on.

    where you car is hitting its rev limiter can give away even more information, if you can only rev to 6500 and then hit a fuel cut then your not in limp mode but one of the requirements for vtec to engauge has not been met.. such as temp, oil press speed, etc..

    IAB solenoid activates on a P13 (91-96) at 4600, and 4900 on a P5M (97-01)
    VTEC solenoid activates on a P13 (91-96) at 4900, and 5200 on a P5M (97-01)

    but if you car is only reving to (i think limp mode if 5000 rpm) then you have something seriously prohibiting the car, and most likely almost definatly your CEL should be on, and like i said fix and present codes befor eyou worry about VTEC.

    and NO vtec does not engauge if you sitting still in your car and reving it, the secondary runners will open up, but the vtec soliniod will not open.

    which brings me to another point, part of what makes vtec work well is the fact that right before the secondary cam profiles engauge the secondary runners in the intake manafold open up to accomadate the engines greater demand for air flow when in VTEC. some times there maybe something wrong with the wiring that tells the IAB soliniod to remove vacume from the diaphram that holds them closed. If anything is wrong with the IAB system then that can cause vtec to feel like it is not engauging. The Iabs are rpm dependant only, and the do open if you reving the car in neutal. THe Iabs are held closed when the car is idling by vacume and continue to be held closed by vacume stored in the small canaster under the intake manifold so you will have vacume to the required rpm even at WOT. With key off and no vacume the IABs open due to a spring. so once vacume is removed they just go to their rest state which is open.

    You might simply have a faulty sensor causing the vehicle to go into a "limp home mode" ie. only one gear is permanently selected just to "get you home".

Limp mode initiates when the enginbe computer(s) note a problem that can cause serious damage to the engine or electricsl components. The car engages limp mode and will not go into higher gers as a protective measure
push in the computer connectors . check your computgers to see if you have a loose connection(s).

2007 honda accord diesel


This is one for the dealer/shops Ian. The Honda diesels are a bit more involved than say an old Cummins. lol I would let them test it with the latest hardware. Also there are some Service Bulletins out on them too. And of course Honda has all the latest of those too. Honda doesn't release anything up-to-date to public/independent shops. To get the latest and greatest, ya gotta go to Honda. Good luck

I have a 1998 honda accord v 6 iwant to sknow where it the tcc or torque converter clutch solenoid in the transmission case i have trouble code p 0740 tcc sol


I am having the same issues with my 98 Accord. The transmission in the car slipped and bucked for a long time, but now it is stuck in limp mode. Most opinions are that the car needs a transmission, but that is horrendously expensive for a 98, so I have been trying other remedies first.

Yesterday, I removed and cleaned the filters behind the lock control/shift solenoid (they were clogged solid), but the car is still more-or-less stuck in limp mode. The lock up control solenoid is the one on top of the transmission directly beneath the thermostat housing.

Here is a link to a video that will help explain torque converter control solenoids: http://www.youtube.com/watch?v=5Jeb0KpAN_g

Also, here is a link to a support group on facebook for 6th generation Honda Accord owners with transmission problems:

2004 Accord sometimes judders as if only started on 2 cyl


Honda makes diesels - awesome.

Well, I know diesels aren't very complicated engines, however when anything goes wrong it's usually the fuel filter. I suggest changing the fuel filter, and see what happens.

Can't think of much else that would cause a diesel to that. And you say it only does it ever now and then, and you have to shut it off and then restart it.

Let me know if you need any further assistance.

You need to have the codes checked. The injectors in your engine have an issue where they either bypass fuel back to the tank or crack the body and fuel goes into the oil pan.

The warranty period goes to 200k miles, sorry I don't remember how many years, I think it was 7 years.

If you had a smoke problem before you used the kleaner you already have an injector problem.

do you plug it in at night and in cold weather? Sounds like a fuel problem. Check your fuel filter and add conditioner to your fuel. Hope this helps.
