DTC P05DB-00: Brake Pedal Position Sensor "B"; DTC P05E0-00: Brake Pedal Position Sensor "A"/"B" [02/2024 - ]: Procedure
- READ VALUE USING GTS (BRAKE PEDAL STROKE SENSOR ASSEMBLY)
Pre-procedure1
- Mount a pedal effort gauge.
- 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).
Procedure1
- Depress the brake pedal slowly and check the brake pedal stroke sensor assembly output voltages with respect to brake pedal depression force.

- CHECK HARNESS AND CONNECTOR (BRAKE BOOSTER WITH MASTER CYLINDER ASSEMBLY - BRAKE PEDAL STROKE SENSOR ASSEMBLY)
Pre-procedure1
- Turn the ignition switch off.
Procedure1
- Make sure that there is no looseness at the locking part and the connecting part of the connectors.
OK
The connector is securely connected.
Pre-procedure2
- Disconnect the A48 No. 1 skid control ECU (brake booster with master cylinder assembly) connector.
- Disconnect the A45 brake pedal stroke sensor assembly connector.
Procedure2
- Check both the connector case and the terminals for deformation and corrosion.
OK
No deformation or corrosion.
Procedure3
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition A48-3 (SKS1) - A45-6 (SKS1) Always Below 1 Ω A48-3 (SKS1) or A45-6 (SKS1) - Body ground Always 10 kΩ or higher Result
Proceed to OK NG Post-procedure1
