Had a 09 hilux in last week.had a few issues
Fuel light on and flashing
abs light on
over boosting causing it to go into limp mode
exhaust leak at egr port in head (ended up acting like a wastgate and keeping the boost under 14psi and not cuting out)
Now I fixed all the problems and run tests to find that the turbo ecu was making it free boost (actually made it really quick)
Replaced the turbo ecu and all is fine
Now my toughts are with the faulty boost ecu.why did it behave in this manor and am I able to find the short or burnt out diod and run a resistor to make adjustable boost?
This is justme brain storming
I also blocked of egr as there was no fixing the factory cooler part as it was completely broken of (engine light has come up but still drives fine)
Was actually thinking of puting faulty turbo ecu back in and running a small wastgate on the egr port in the head on plen side and plumbing it back into the egr port.making it have adjustable boost??
Hope this makes sence.
Any thoughts
