TROUBLESHOOTING
-
Wastegate not actuating - Confirm continuity of wiring, manually adjust butterfly position and feel for binding.
-
Poor wastegate actuation
– Ensure wiring is correct, check for dirt and smooth operation by manual over-ride, ECU that is
driving the butterfly may not be set up correctly.
-
Wraparound of signal on position sensor
– Turbosmart Pre “time” every sensor, contact Turbosmart if this occurs.
-
Wastegate fluctuates and fails to find targeted position, motor wires may be the incorrect way. Swap and test to see. Ensure to
use sensible current limits to prevent over currenting.
-
Wastegate seized
– Remove cap and manually move butterfly feeling for resistance.
-
Wastegate moves but sensor not reading
– Check connections.
-
Boost creeping at high rpm - Wastegate flow path is poor, wastegate is too small for the application.
-
