Hi all,

I hope I can find some help on here as I'm at my wits end with this car.

As the title says, I have a 2008 Fiat Panda 1.1 Active.
A few months back I hit a rock in the road and engine mounting broke which snapped the cambelt.

Having mountings repaired, cambelt and pully replaced, timing set correctly etc, the engine turns but there is no power to the injectors.

I have taken it to a local mechanic who had ran the OBD, came up with 9 errors, 6 of which he cleared though 3 keep coming back:
PO202 - Injector circuit open
PO351 - Coil circuit open
PO352 - Coil circuit open

He keeps referring to the key code being an issue, but as far as I understand, that if that is the case then the ignition wouldn't work either, I suspect a wiring issue as no signal is being sent to the Injectors or the Coil from the ECU.

Please keep in mind that I am a far throw from knowing the inner working of the car, so please use small words

Any advice in this regard will be greatly appreciated.
TIA

Hi. That reads like a problem with electrical wires..

The 1.1 suffers from wires breaking in the big cable connector to the ECU that sits on the engine. Get an auto electrician to check those wires and fix anything weak or broken.

ECU Testing Ltd can probably help if the cable connector or ECU are damaged.

Thank you for the quick replies, I'll tell the mechanic and see where it takes me

Inertia switch under the seat ok?

Yes, the switch under the passenger seat is fine.

if there so a problem with the key you should get a light on the dash and a U1600 code

p0351 or p0352 normally pop up if one of the coil packs is disconnected

Hi All

does the 1.1 have a crankshaft rotation/position sensor, if the pulley had been replaced due to impact did it knock the sensor or even move it on its bracket slightly away to not sense movement.

As far as I know, it does and it was not hurt, but would a OBD not pick that up?

Unfortunately where we stay there aren't any auto electricians... go figure, is there anywhere I can download a wiring diagram for this Panda?

Without a signal from the cranksensor the ECU will simply think it doesn't turn. So no fault will be stored to be read via OBD.
IMO the distance between pulley and sensor should be about the thickness of a creditcard.

Crank position sensor can sometimes fail when hot (not your problem I know) but there is no fault code because the ECU behaves as if the engine simply stopped turning. New sensor - sorted.

However, I suspect that is unlikely to raise ignition and injector fault codes, so the ECU wiring looks like the best place to check.

By the way, many auto sparkies are mobile. Google is your best bet or ask at the garage who they would use.

Hey, just got a Fiat Panda 1.1 myself.


I was having issues with randomly stalling and starting, so I poked about on this forum and found this video on it (which I can't bloody post). The ECU has two plugs, big one and a smaller one. The video showed wiggling the smaller one and it stalling.

So went to my car, poked the wires and it stalled. Tried again, stalled. Took off the plug, took off its cover, sprayed everything down with contact cleaner, re-zip tied everything so it was proper support and now it seems good.


But that was a couple days and 150mile ago so far.

what's common between injector's and coil's


might be worth looking at the fuses and relays ?

disconnect the battery (store any radio codes etc if you need to) remove both ECU plugs spray them with contact cleaner (not wd40!)
connect and disconnect a couple of times to help clean the pins.
If the main wiring loom is pulling on the plugs pull the loom up and support it with tie wraps etc.
reconnect the plugs, reconnect the battery and try starting, if the engine runs ok, strap the two ECU plugs down with long tie-wraps.
if not try lifting the wiring loom and see if it makes a difference (the weight of the loom can pull the pins out of the ECU sockets.)

I eventually placed a long wooden spoon handle across the top of the ECU strapping the plugs and the wiring loom to it for support, not had an issue since and my MOT inspector was impressed with my simple fix.
