Hello
I have a problem with Ford Focus 1.6 16V '02:
the car started working on 2 cylinders, the service checked the ignition coil (ok) and found the damage / need to change the ECU (EEC-V).
The car went to me, I undressed the driver and found the damage to one of the transistors that keyed the HV coil, marking this element:
5401DM
N213
ABH
(housing such as TO220 only in SMD version)
I did not find any information about this transistor, but I found an old, damaged EEC-IV from a fiesta that has a similar ignition system.
The transistor in this controller has the designation 5101FGAA (housing TO220)
I converted it to SMD
, soldered to the focus and it works, but the car works equally only at low revolutions, at higher the engine starts to work as if it were 3 cyl and does not have the power it should.
Now a few questions for you:
- Does anyone know the parameters, the equivalents of these transistors?
-Why the assumption of a transistor with slightly different parameters can give such symptoms, or look for a reason elsewhere (candles, catalyst)?
- Does driving on 2 cylinders for about 5km (customer swears no more) could damage / melt the catalyst?
Thank you in advance for your regards and greetings
