Cutting Out

[dobbey1]

Please Help Me!!!!!!!!!!!!!!!!!!

Hello i hope someone can help me, i own a toyota avensis on an 03 plate, with an D4D diesel engine , it has in intermittant fault where it will just cut out, when on the motorway traveling around 70 mph, when it cuts out the TLC and VSC warning lights will come on and i have to pull onto the hard shoulder, i then turn the ignition off and then back on and the car starts up straight away, im left with the TLC and VSC on all the time, after about a week after this fault occurrs the lights go out on the dash display, i have taken it to a toyota dealer, and they said it had stored these codes

C0371 Yaw rate sensor

C1201 Brake Boost sensor

C0125 Valve relay circuit open

it would appear that these faults are brake issue faults which i asume would not cause the car to cut out like it does, the toyota dealer told me it was coz i had gone over some speed bumps, well if the car cant go over speed humps what can, at that point i took it out of the toyota dealer, so now i am trying to see if anyone else has had a similar problem and could anyone help in this matter , this fault will only happen every 2/3 months.

all advise would be greatly appreciated

Ok

The chances of all these sensors going bad at same time is NIL. So you must have done something to the car, for it to start to throw these errors.

I would tempted to say this is driver error, and you may have caused the problems yourself.

I would recommend.. you get under the car with a nice bright tourch and inspect all the wiring loom, I suspect that one wiring loom, or a part of it has been caught and damaged and will need repair.

Also with these errors, the ecu will need to be reset and the rom would need to be erased orelse the errors will contiune to reappear.

Check the wiring loom first, and then post back.

happens to mine too, the cure is to change the oil, don't ask me why it works but it does, fault usually reoccurs after 10k, change oil, fault goes away

don't know, no lights and the level was OK.

I just regard it as notice to change the oil if it reoccurs
