Toyota 6-Pin PDC Reversing Radar Sensor Connector – OEM 89341-02040 | Black & White Male Female

The OEM 89341-02040 is a 6-pin connector used in Toyota Parking Distance Control (PDC) reversing radar sensor harnesses. Available in Black and White housing colors to match different OEM bumper harness positions, Male and Female variants, bare or with 15cm pre-wired leads. The 6-pin configuration integrates PDC sensor power, ground, ultrasonic signal, temperature compensation, sensor ID, and diagnostic circuits for Toyota’s parking sensor system.

Toyota PDC System – Why 6 Pins for a Parking Sensor?

A basic parking sensor requires only 3 circuits: power, ground, and ultrasonic signal. Toyota’s OEM PDC system uses a 6-pin connector because it integrates additional circuits:

• Pin 1 (Power): 12V supply to sensor
• Pin 2 (Ground): Chassis earth
• Pin 3 (Signal): Ultrasonic transducer signal (transmit/receive)
• Pin 4 (Temp): Built-in temperature compensation circuit — ultrasonic speed of sound varies with air temperature; Toyota’s PDC ECU uses this to maintain accurate distance measurement across temperature ranges
• Pin 5 (ID): Sensor identification — each sensor has a unique ID allowing the PDC ECU to identify which sensor is detecting an obstacle and display the correct position on the multi-information display
• Pin 6 (Diag): Diagnostic circuit for sensor self-test — allows the PDC ECU to detect a failed sensor and generate a specific fault code

Black vs. White Housing – Which Do I Need?

Toyota uses two housing colors to identify sensor position in the bumper:

• Black housing: Outer sensors (corner positions)
• White housing: Inner sensors (centre positions)

The color coding prevents mis-mating during bumper removal and reinstallation. Match the housing color to the original OEM PDC sensor connector position in your Toyota bumper harness. If unsure, check the Toyota wiring diagram for your specific model and year.

Common PDC Fault Symptoms

• Continuous PDC warning tone when reversing (sensor fault detected)
• PDC system warning light on dashboard
• Specific sensor position fault on Toyota Techstream (e.g., “Rear Right Sensor Circuit”)
• PDC system completely inactive (all sensors failed — check power/ground pins)
• Intermittent PDC operation (connector locking tab broken, connector working loose)

Frequently Asked Questions

Q: What fault codes indicate a failed PDC sensor connector?
A: On Toyota Techstream, PDC sensor connector faults appear as specific sensor circuit faults (e.g., “Rear Right Sensor Open Circuit” or “Rear Left Sensor Short Circuit”). The PDC ECU can identify the exact sensor position because each sensor has a unique ID on Pin 5.

Q: Can I replace just the connector without replacing the sensor?
A: Yes. If the sensor itself is functional but the connector is corroded or the locking tab is broken, replacing the connector is the correct repair. Test the sensor by measuring the ultrasonic transducer resistance at the sensor pins (typical: 10–30Ω) before ordering a replacement sensor.

Q: Why does my PDC work sometimes but not others?
A: Intermittent PDC operation is a classic symptom of a broken connector locking tab. The connector appears plugged in but works loose under vibration, causing intermittent open circuits on the sensor signal or power pins. Replace the connector housing to resolve intermittent faults.
