Long story short was having problems with my car idiling and assumed it was a diesel problem. I replaced the in tank pump, fuel regulator, filter, maf and still no joy. It then got worse so i got it tested and codes came out as follows.
1614 control unit sensor voltage 1/2 (ECU) signal too low
0221 accelerator pedal position sensor 2
0121 accelerator pedal position sensor 1
0190 Rail pressure sensor
0380 glow relay over current
1517 immobilizer
0230 solenoid0operated shut off (ELAB) signal improbable
Was told to check all ecu cables and test. and also check all earth wires by mechanic.
Can anyone help me with finding out what wire does what on ecu and what volts it is meant to be. and also the earth wire location.
Thanks in advance
