6-Pin Toyota Accelerator Pedal Connector — OEM 90980-12303 / 6189-1083 | DJ7062Y-0.6-11 | Waterproof

The correct replacement connector for the Toyota accelerator pedal position sensor (APPS) wiring harness, matching OEM part numbers 90980-12303 and 6189-1083. The accelerator pedal position sensor is a critical engine management component — it communicates the driver’s throttle input to the ECU via a variable voltage signal. A damaged, corroded, or melted connector causes erratic throttle response, engine hesitation, throttle stuck open/closed, and in some cases limp mode activation. This 6-pin waterproof connector (DJ7062Y-0.6-11) uses PA66 housing with rubber seals to protect the sensor connection from moisture, heat, and vibration in the pedal box environment. Available as a male connector set or pre-wired 15cm harness.

Compatible Toyota Models

This connector is used across a wide range of Toyota and Lexus vehicles equipped with the electronic throttle control (ETC) system. Cross-reference OEM part numbers 90980-12303 or 6189-1083 in your vehicle’s parts catalogue to confirm fitment for your specific model and year.

Accelerator Pedal Sensor Connector Failure Symptoms

Erratic throttle response — intermittent signal loss causes the ECU to receive inconsistent throttle position data
Engine hesitation or stumble — signal dropout during acceleration causes momentary power loss
Throttle stuck or unresponsive — complete connector failure causes the ECU to default to a fixed throttle position
Limp mode activation — the ECU detects an out-of-range throttle signal and activates limp mode to protect the engine
DTC codes — P0120, P0121, P0122, P0123, P0124 (throttle position sensor circuit faults)

✅ 6-pin configuration — covers all signal, power, and ground circuits in the accelerator pedal position sensor harness
✅ Rubber sealed — individual wire seals and body seal protect against moisture and contamination in the pedal box
✅ PA66 housing — flame-retardant nylon 66, resistant to automotive fluids and temperature cycling
✅ CE certified — meets European automotive electrical component standards
✅ Pre-wired harness option — 15cm colour-coded leads for fast splice repair

Repair Procedure

Locate the accelerator pedal position sensor connector under the dashboard at the pedal assembly.
Disconnect the battery negative terminal before starting electrical work.
Unplug the damaged connector from the sensor. Inspect the sensor terminals for damage.
Cut the damaged connector from the harness, leaving maximum wire length.
For the 15cm harness option: splice each lead to the corresponding vehicle wire using waterproof butt connectors or solder + heat shrink. Match wire colours carefully.
Reconnect the battery and clear any stored DTC codes with an OBD-II scanner.
Test throttle response through the full pedal travel range before road testing.

Frequently Asked Questions

Q: My car is in limp mode — could this connector be the cause?
A: Yes. A failed accelerator pedal sensor connector is a common cause of limp mode on Toyota vehicles. Check for DTC codes P0120–P0124 first. If the connector is visibly damaged, corroded, or has melted terminals, replace it before clearing codes.

Q: Do I need to reprogram the ECU after replacing the connector?
A: No. Replacing the connector does not require ECU reprogramming. Clear any stored DTC codes after the repair and perform a throttle position sensor reset procedure if required by your vehicle’s service manual.
