DTC No. DTC Detection Condition Trouble Area
P0A94-585

Boost converter voltage (VL) sensor performance problem

When not boosting, differences between "VL-Voltage before Boosting" and "Power Resource VB", and "VL-Voltage before Boosting" and "VH-Voltage after Boosting" are large.

P0A94-585

  • VL-Voltage before Boosting

  • Power Resource VB

  • VH-Voltage after Boosting

  • Boost Ratio

INSPECTION PROCEDURE

Tech Tips

When the accelerator pedal is not depressed with the power switch on (READY) and the shift lever in P, if "VH-Voltage after Boosting" and the "Power Resource VB" is approximately same after repair, the condition is judged as normal.

PROCEDURE


  1. CHECK DTC OUTPUT (HYBRID CONTROL)


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.

    4. Check for DTCs.

      Tech Tips


      • *1: If any INF codes are output for this DTC, refer to the corresponding diagnostic procedure.

      • P0A94-585 may be stored due to a malfunction which causes the DTCs in the preceding tables to be stored. In this case, first troubleshoot the output DTCs in the preceding tables. Then, perform a reproduction test to check that no DTCs are output.

    5. Turn the power switch off.
