hi all,

mitsubishi l200 K74 2.5TD trojan 56 plate.... (4D56T engine)

i just recently had the EML on and the code is (52)variable geometry control pressure sensor system. i have replaced the boost pressure map sensor (behind the intercooler), turbo actuator, 3mm rubber hoses for the vacuum lines, turbo solenoid (brown one) well both, checked the wiring connectors all seem fine no corrosion. when i started the engine with the old turbo actuator WG on and it didn't move, so replaced it with a new one. at first, on idle the new turbo actuator wategate was working hitting the top screw. took for a test drive, there was no power and uphill the EML came back on code (52) same problem. checked the new actuator on the turbo at idle and nothing, sat on the bottom screw.

just ordered (not replaced yet) 16/04/20.
new air intake boost pressure map sensor (the one on the intake manifold).
new TF035 Turbo cartridge CHRA just incase.


now am running out of ideas what it could be.....
please any help would be welcomed.. [help]

thanks jon....
