Polo engine cutting out - help needed

[Crasher]

00609 Ignition output 1 Open circuit/short to earth

1)Wiring open circuit in earth wire
2)Wiring has short to earth


If this code keeps coming back with a new coil, you have a wiring fault which could be in the wire between the body and the engine or a poor connection where the coil picks up its earth.

hi - thanks - i will get this checked but wil this be the cause of the car slowing down ?

[Crasher]

If the coil receives a poor earth, the spark will be poor so therefore will the engines power output.

hi - my mechanic ckecked all the leads and couldnt find any prob with earth but he connected a new cable from battery to engine coil and all code cleared and never came back so i thought the prob had gone.........BUT as i was driving earlier it started jerking again as if it was about to lose power again..... so looks like something else is causing this....

any ideas?

[Crasher]

Fault code read and start from there.

sorry i dont understand last message

[Crasher]

The first step would be to have a fault code read done and see what is stored. If it is the same code as before then that needs pursuing deeper and if there is another code, have that looked into. If there are no codes it is a fault outside of the ECU’s abilities to detect it and that helps as there are only certain things that can be.

well once the new earth lead was attached the code was gone and never came back. so i am gonna drive it over the weekend as it did judder earlier and then see if any codes are back....

if not what do u think it would be?

[Crasher]

I will reserve judgement until I know the results of a code read.

hi - crazy day - loss of power occured 4 times today .. once at 50 mph.... nearly resulting in an accident but anyway......... had the car checked again and this is the code :

00519 Manifold Absolute Pressure Sensor G71 - not a plausible signal. error occurs intermitently.

hope that makes sense to you.

thanks
