Hi guys,

Put a 1.2 engine z12xe in a corsa c, it had a 1.0 z10xe 3 pot in there.

I mapped the ecu with the correct map for 1.2.

However I have this error:

p0202 injector circuit open

Im so confused, the injector is getting a volatage through the wires, ive changed the injector...

Its just weird, as look at the wiring differences:

Here is the 1.0:

Pin 51, 2, 34 are the injectors on the engine harness loom.

And heres the 1.2:

See, 51, 2, 34 are what were on the 1.0... and Injector 2... is new, pin 18.

And thats the one causing the issue...

What I dont get is... The engine harness new one is obviously from the 1.2 engine... and the ecu is now mapped to 1.2...

So surely the injector should work ok?

But its not, engines down on 3, no improvement over the 1L then

Could anyone PLEASE help, im not sure if something needs running to the relay or something along that lines?

Regards
