Spn 641 engine variable geometry turbocharger actuator 1

However, wastegated turbochargers for gasoline engines have seen rapid development and the potential benefits of variable geometry turbochargers have been harder to justify [2729][2730]. In 2016, Volkswagen revealed the EA211 TSI evo gasoline engine that would use a Honeywell turbocharger with a variable geometry nozzle turbine. On your turbocharger, you've got an ECM that's controlling an actuator. That ECM sends a signal out to your actuator, telling it things like: "Hey, the engine needs more air, so you need to move." Then it gets a reference back. If it sends 5 volts out and it's supposed to move 30 degrees, then it's supposed to get something like 3 volts back.
