Brake Booster Pressure Sensor Inspection

NOTE:  Since there is no direct method to test the inspection item, troubleshooting is performed using a known-good component.

Test Procedure 

• Install a known-good brake booster pressure sensor and attempt to reproduce the failure.

Results 

• If the failure is reproduced, there is a problem with other related components.
• If the symptom/DTC goes away, the brake booster pressure sensor must be faulty.
