03 Fabia 33k miles 1.2   3cyl   with EPC light and P1558.  Where can get wiring diag for ECU and sensors? 

 

Car broke down twice in 2 months with ig coil meltdowns.

 

Now - the third time - engine turns over as normal but doesnt fire. EPC light is on. Breakdown man disconnected battery, checked a few fuses and it still turns over but doesn't fire.  Read codes then cleared them and tried to start engine again. EPC light on, code G186 P1558 17966  which says Throttle actuator electrical malfunction.  I want to check the wiring between sensors/actuators and ECU but all the diagrams I can find are for the electrical systems not the electronics.  Anyone know where I can get a wiring diag for the ECU and sensors and any other hints about the fault?

Here's a page for the (2001 AWY engine) throttle body and its connections to ECU. Can dig out more as reqd. Maybe PM me an email address?

 

 

What's the engine code of your car?

AZQ

On this link there does appear to be a 660+ pages of 200-2002 Fabia 1 wiring information but litttle for the 2003 AZQ engine so I'll try  the 1.2L AWY wiring assuming it is similar.
