i was changing the spark plugs to bosch irrideums i took the correct steps when i got to lifting the Manifold! had a freind holding it so i could cover the ports @#$% he let it slip out of his hands @#$%er!! finished installing and reset the ECU upon restarting @#$%^it! p0122 came up done the research changed the ThrottlePS, Accltr pedal ,ECU but have not put in just in case? pulled the ECU saw that 2 IC F5018 was showing 4.53ohm should be 5.55 so i reflowed ecu voltage came bacc but Limp mode did not clear and now acc pedal not working?
the fix should be change ECU program myself with Mangoose in route or any of JFFamily have ADVICE Support Needed PLEASE

Changing IC chips on a module is a thing that would be questionable at best. First off, I would need to look at all the numbers on a chip to figure out what the chip really does. There is a method to the madness with the numbers on a chip and if you can decode what the numbers mean, you can get a pretty good idea of what the chip does in the circuit. But, that is a lot of research. Then you get into the whole ESD world of handling the chip just so so that you don't give the chip a static shock and destroy the chip simply by handling it. With the chip on the board, it is pretty shock resistant. when it is by itself, it can be destroyed by something that you don't even see. so, unless you have a special ESD mat and grounding setup, I would have to advise against it.

The final thing that makes this sort of repair difficult is getting the chip desoldered without overheating the chip and killing it that way. With patience and experience, you can get the chip out and not destroy it. But, if soldering is your hobby, more likely to end up bad for you than it will be good.

 

true! it was just an option so whats your take on the p0122

 

it was just an option i work on PCBs component level THESE are the ICs in question

 

Do you have the chip numbers?
from the look of them they look like Mosfets.

 

Yes Sir! that would be Fiji F5018 fets so this morning i installed the replacement ECU everything normal except turng Ign, to start up NoGoo!! so guess im looking to Flash, Reprogram or is there a wayto get this down cheaper and faster than "the not Option Dealer" thanks JF,Family

Cash.
The F5018 is a Mosfet.
the simple exploration of what these do are they are high current transistors
which is essence a switch.
the 3 legs are the connections and the top solder joint is the heat sink and ground.

a Quick search on google and found these.

you could just replace them no programming required.

 

Paulc732 My thoughts exactly,wanted to share my experience with everyone that had the dtc code p0122 short/ground low circuit throttlr/pedal sensor/wire Driver to throttle body im going to change them and will update you on the fix to be certain thanks for the support
