Hi , Ihave a problem with my 99 2.5v6 cdx. Under normal driving conditions my traction control warning light comes on, then its followed by the engine dying verry briefly. feels like running out of fuel. This keeps happening until engine is turned off, restarted then light goes out and its fine for 10 miles or so before it starts happening again. Any ideas?

traction control light coming on means its sending signals to take the power off the rear wheels (hence feeling of engine briefly dying), which in snow or wet conditions where you'd normally skid, would mean you dont lose control

my immediate thought is check the tread depth on your rear tyres, other than that if that fails, i'm thinking something is telling your car that your wheels arent experiencing any resistance towards the road surface (ie lack of traction!)

Follow the guide on here for reading the engine fault codes.

I suspect you may have a dying crank sensor (expect a code 19) and the TC light is being thrown due to a corrupt RPM signal to the ABS unit

Showing no fault codes, cleared ECU 12 months ago when i changed the cranksensor. I,ve pulled the ABS fuse to see if it still does it. Have to wait and see because it,s one of them infuriateing intermittent problems.

I have seen a car do similar things before. TC would kick in as soon as the car got up to 15 MPH or so. Occasionally, it would just throw a fault, ABS and TC lights would come on and it would drive normally thereafter. Couldn't read the ABS/TC codes with a cheapo Tech 2 but the engine was clear of codes. Turned out to be a combination of a faulty ABS ECU and some butchering of the wiring to the ABS wheel sensors IIRC. Speedo worked normally throughout.

Pulling the ABS fuse allowed the above car to be driven (without a speedo).

im not sure if its diffrent on later cars, but on my 94 omega if the fuse is removed the speedo still works, it only disables the TC and ABS

[Kevin Wood]

Maybe earlier cars are different, but on later models the speedo signal comes from the ABS wheel sensors via the abs ecu.

Does on earlier cars as well  :-/ - maybe earlier ABS units are dual fed?

[jim_c]

Thanks for the info, driving round with no speedo at the moment to see if it stops it. Good job my tomtom gives the speed. Thanks again, Jim C.

Be careful, TomTom under reads in my experience (taking in to account the speedo overread)
