Monitor Description

WARNING: This page is about a different variant/trim than selected.
  1. The ECM receives signals such as requested engine torque, target engine speed and engine cranking status from the hybrid vehicle control ECU assembly.
  2. The ECM controls engine start and stop and the throttle valve angle based on the signals received from the hybrid vehicle control ECU assembly.
  3. The ECM receives the actual engine torque calculated by the hybrid vehicle control ECU assembly based on the generator torque.
  4. When the actual engine torque is less than 20% of the requested engine torque*, the ECM judges that the engine output is abnormal and stores DTC P3190-00.

    (The engine may not have started in the above situation.)

    1. *: Requested torque = Requested Engine Torque (kW) / HV Target Engine Speed (rpm) x 9549
  5. If the ECM does not detect engine start torque (actual engine torque) even though it has received an engine start request and started the engine, it stores DTC P3191-00.

    HINT: 

    • When DTCs P3190-00, P3191-00 and P3193-00 are output, the engine may be stopped due to the engine condition.

      At this time, after adding fuel or performing repairs, clear the DTCs. Then turn the ignition switch off to return to the normal condition.

    • When this DTC is output and the engine is stopped, the HV battery cannot be charged since the vehicle is driven with the motor only. If the vehicle continues to be driven under this condition, the HV battery will become depleted and the ignition switch will not be able to be turned to ON (READY).
    • When DTC P3190-00 or P3191-00 is stored, the engine torque has dropped by 80% or the engine cannot be started. If any DTCs that indicate malfunctioning of engine related parts are stored at the same time, repair the malfunctioning parts first.
    • If engine knock is detected due to mechanical noise or a knock control sensor being loose, the ignition timing (Knock F/B Value, Knock Correct Learn Value) may be excessively retarded and DTC P3190-00 may be stored.
