Hi
So, my lad owns a Fiat Punto Mk2 and had issues with an intermittent engine cut out, which was recoverable after a short while but was putting the engine management light on. I owned a cheap and cheerful Wi-Fi obd2 scanner at the time which brought up an ignition coil fault (can’t remember the code)
Anyhow, after going round all the electrical connections under the hood, trying to get the fault to occur again, I decided that as the car had not had plugs or leads for some time, and that I might as well start there and work my way to the coil, just to see if the intermittent fault would go away.
As I remember, I’m sure the car had more than a week or so of trouble-free running, until one day it threw the fault again, it did not cut out but apparently felt like it was going to.
I then decided to buy a second-hand coil pack, which has since been fitted and all seemed good, all except for the engine management light kept randomly going on and off.
Now, I have since managed to pick up a better bidirectional scanner which has thrown these codes up:
5012 Vehicle Speed (From CAN) DELPHI Electric Steering D601 CAN Line DELPHI Electric Steering
5013 Alternator Status (From CAN) DELPHI Electric Steering
B1011 Door Lock, Motor Faulty Delphi/Marelli Body Computer
U1601 CAN Line Error, Wiring Faulty Delphi/Marelli Body Computer
U1602 CAN Line Error Injection - Magneti Marelli IAW 4AF/4EF/59F/5AF Outside EEC
U1600 Electronic Key Injection - Magneti Marelli IAW 4AF/4EF/59F/5AF Outside EEC
P0352 Coil 2 Injection - Magneti Marelli IAW 4AF/4EF/59F/5AF Outside EEC
P0351 Coil 1 Injection - Magneti Marelli IAW 4AF/4EF/59F/5AF Outside EEC
P0204 Injector 4 Injection - Magneti Marelli IAW 4AF/4EF/59F/5AF Outside EEC
P0201 Injector 1 Injection - Magneti Marelli IAW 4AF/4EF/59F/5AF Outside EEC
P0203 Injector 3 Injection - Magneti Marelli IAW 4AF/4EF/59F/5AF Outside EEC
P0202 Injector 2 Injection - Magneti Marelli IAW 4AF/4EF/59F/5AF Outside EEC
P0135 Lambda 1 Heater Above Catal. Injection - Magneti Marelli IAW 4AF/4EF/59F/5AF Outside EEC
I know the steering once went heavy and the steering light came on, but that was months ago and has not happened since, but as for the rest, I was wondering if the coil may have damaged the ecu maybe?
Do you think it might be worth trying an ecu, or do you think its somewhere lurking in the wiring?
