2007 Tacoma ex cab 2 wheel, 39000 miles, 4 cyl eng,
does not come on while engine on
Ok, this makes it clearer to me then.
The check engine light cam on and flashed because the computer recognized a severe misfire......if the light is not on now then this may have been something simple such as a flooded engine resulting in a quick misfire until the engine cleared out.
If this is the first time this has happened and has not happened again then I would not be worried about it. If a constant problem is recognized the check engine light would set on solid when running. It's easy to flood these engines if you start the truck and shut it off before it warms up, it uses a lot of fuel when cold, then when you start again it already has a lot of fuel in it and keep on dumping it in when started again.
this sounds good but it has been happening without the engine running since yesterday only this was the first time that it happened when the engine was on
When you turn the key to "on" it should run a bulb chek and turn the light on solid for 2-3 seconds......once the car is started it should be off unless 1- a code is stored, it goes on solid or 2- a storng misfire is detected then the light flashes until the condition is no longer recognized
If the light flashes with the engine OFF then you have an issue with a short in the instrument cluster or a ECM issue.....honestly never seen that one on ANY toyota product.....unless you have something aftermarket wired to the truck that is causing this or possibly a water leak that has caused corrosion in the junction block. If you don't have an extended warranty on the truck and this is indeed the case with the engine off then be prepared for an expensive and in depth diagnostic........the only part still covered is the computer (ECM) by a 8 year/80,000 mile warranty
thanks I am looking for a brighter picture when there may not be one, this vehicle is virtually brand new at 39000. I am miffed dumbfounded and a host of other things an releaze that there is very little recourse for me I am not well versed in gaining the codes although I know that it can be done I have never attempted to do it with any vehicle let alone this 2007 2.7 ltr 4 cly toyota truck and it is to late on a sunday to get it checked at the auto zone for the codes. would a emmision station be able to diagnose the problem if it is related to an emissions problem and what exactly is a misfire in laymans terms
