Recommended Posts

Hey all

As title sais

Whenever i start to build boost engine managment light comes on

Getting fault code 12

have no idea why as the car runs absoloutly fine

Only thing i dont have attached to the car since doing engine swap is this bracket with a blue hose , cant see anywhere that it fits to the engine.

Looks like the hard line from the turbo actuator up to the high/low boost solinoid - wont cause your issue



How much boost are you running?



12 is usually a signal issue from the dizzy to ecu

Have you taken a look at the dizzy and wiring back to the ecu? The wiring is shielded from factory so it may be worth checking its all still intact? Don't suppose you have access to an oscilloscope? You could confirm the output signal from the 24tooth and syncs to make sure the waveforms are as even?
