Electronic throttle control system

The ECM cuts off throttle actuator current and the throttle valve is returned to a 5.5° throttle position by the return spring.

The ECM stops the engine and the vehicle can be driven using solely the hybrid system.*

Pass condition detected and then power switch turned off

Knock control sensor

The ECM sets the ignition timing to maximum retard.

Power switch off

P0352

P0353

P0354

Ignition coil assembly

The ECM cuts the fuel injection.

Pass condition detected

P0401

P0403

EGR valve assembly

ECM assumes that EGR valve assembly is closed, so that ignition timing controlled to a safe valve.

Pass condition detected and then power switch turned off

P2237

P2238

P2239

P2252

P2253

Air fuel ratio sensor

  • Air fuel ratio feedback control is stopped.
  • Current to the air fuel ratio sensor heater is cut.

Pass condition detected and then power switch turned off
