156 1.9jtd 16v m-jet overboost
Hi, i am new to this forum so please forgive me any mistakes i might make.
Somebody please help,i have the engine managment light on with the fault codes P0220 TPS P0190 Fuel rail pressure sensor P0235 MAP Sensor. Engine revs to 3400rpm i guess its in limp home mode.I have replaced with new genuine parts TPS Sensor, EGR Valve,Map Sensor,MAF Sensor also striped and cleaned turbo, replaced small vacum hoses and checked all other hoses.I have also cleaned and checked as many connectors as i can find.
After all this the car is still doing the same and my local Alfa Specialist cannot clear the faults.The costs are now mounting up and have been told it could be ECU problem so before i buy new ECU have i missed something.I have spoke to a couple of ECU specialsts who say this ECU cannot be bench tested is this true.I have also tried manual ECU reset but no difference made fault codes still present.The turbo acuator moves when you start the car but how much it is supposed to move i am not sure.The only things left to replace are the fuel pressure sensor and the VNT solenoid on the radiator but i dont want to keep paying out for sensors that make no difference.
Somebody please help as i want to get my beautiful 156 bake on the road as i have taken it off as i do not want to do any damage.
