Inspection Procedure

HINT:

• The following condition may also cause DTC P0505 to be set:
  • The throttle valve is not fully closed, (e.g. The accelerator pedal is slightly depressed by something such as a floor mat overlapping the accelerator pedal.)
• Read freeze frame data using the Techstream. The ECM (included in the hybrid vehicle control ECU) records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.

1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0505) 
   1. Connect the Techstream to the DLC3.
   2. Turn the power switch on (IG).
   3. Turn the Techstream on.
   4. Enter the following the menus: Powertrain / Engine and ECT / Trouble Codes.
   5. Read the DTCs.
