Toyota / Lexus 6-Pin 2.2mm Accelerator / Throttle Pedal Position Sensor Connector – OEM 7282-7064-40 / 7283-7064-40
Direct OEM-specification replacement for the Sumitomo 6-pin wire harness connector used on accelerator pedal position (APP) sensors across Toyota and Lexus platforms. Cross-references Sumitomo OEM part numbers 7282-7064-40 (male housing) and 7283-7064-40 (female housing). Uses the 2.2mm contact series in grey nylon housing — the 6-pin design is used on Toyota’s drive-by-wire (electronic throttle control) systems where the accelerator pedal position sensor uses dual redundant circuits for safety, requiring 6 pins (two independent 3-pin sensor circuits in a single connector).
A failed APP sensor connector causes the ECM to lose accelerator pedal position data, triggering P2120–P2127 (accelerator pedal position sensor circuit) fault codes and forcing the engine into a limp-home mode with severely restricted throttle response. On Toyota drive-by-wire systems, a failed APP connector is a safety-critical fault — the vehicle will not accelerate normally until the fault is resolved.
| OEM Number | Type | Application |
|---|---|---|
| 7282-7064-40 | Male (plug) housing | Sumitomo 6-pin APP sensor connector — pedal side |
| 7283-7064-40 | Female (socket) housing | Sumitomo 6-pin APP sensor connector — harness side |
| Pin | Circuit | Function | Failure Symptom if Open |
|---|---|---|---|
| 1 | Sensor 1 | 5V reference supply | P2120–P2123, limp-home mode |
| 2 | Sensor 1 | Signal output to ECM | Throttle response lost |
| 3 | Sensor 1 | Ground / earth | Sensor 1 inoperative |
| 4 | Sensor 2 | 5V reference supply | P2125–P2127, limp-home mode |
| 5 | Sensor 2 | Signal output to ECM | Redundant circuit lost |
| 6 | Sensor 2 | Ground / earth | Sensor 2 inoperative |

Q: My Toyota went into limp-home mode with a P2122 fault — could it be the accelerator pedal connector?
A: Yes. A corroded or open 6-pin APP sensor connector is a common cause of P2120–P2127 on Toyota drive-by-wire vehicles. Inspect the connector before replacing the accelerator pedal assembly.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
