DTC P05DB-00: Brake Pedal Position Sensor "B"; DTC P05E0-00: Brake Pedal Position Sensor "A"/"B" [11/2021 - 03/2024]: Procedure

1. Mount a pedal effort gauge.
2. Turn the ignition switch to ON (READY) and depress the brake pedal once.

   HINT: 

   Depress the brake pedal after turning the ignition switch to ON (READY) to set the vehicle to linear mode (switching solenoid (SSA) on).

3. Depress the brake pedal slowly and check the brake pedal stroke sensor assembly output voltages with respect to brake pedal depression force.

1. Turn the ignition switch off.
2. Make sure that there is no looseness at the locking part and the connecting part of the connectors.

   OK

   The connector is securely connected.

3. Disconnect the A39 No. 1 skid control ECU (brake booster with master cylinder assembly) connector.
4. Disconnect the A41 brake pedal stroke sensor assembly connector.
5. Check both the connector case and the terminals for deformation and corrosion.

   OK

   No deformation or corrosion.

6. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   A39-3 (SKS1) - A41-6 (SKS1)	Always	Below 1 Ω
   A39-3 (SKS1) or A41-6 (SKS1) - Body ground	Always	10 kΩ or higher
