(See HBC-644, "Removal and Installation" NG >> Repair or replace harness or connector. 8. CHECK HARNESS AND CONNECTOR (HYBRID VEHICLE CONTROL ECU - ACCELERATOR PEDAL POSITION SENSOR) 1. Turn ignition switch OFF. 2. Disconnect connector E66 from the hybrid vehicle control ECU. 3. Turn ignition switch ON. 4. Measure the voltage according to the value(s) in the table below. NOTE: Turn ignition switch ON with the accelerator pedal position sensor and hybrid vehicle control ECU connec- tors disconnected causes other DTCs to be stored. Clear the DTCs after performing this inspection. 5. Turn ignition switch OFF. 6. Measure the resistance according to the value(s) in the table below.
