6-Pin 2.2mm Throttle Pedal Connector OEM 6189-0369 / 6188-0209 / 90980-11290 / 90980-11289 Toyota Honda Nissan
Direct OEM-specification replacement for the 6-pin 2.2mm waterproof connector used on electronic throttle pedal position sensors (APPS) across Toyota, Honda, and Nissan platforms. Cross-references Yazaki OEM numbers 6189-0369 (female housing), 6188-0209 (male housing), 90980-11290, and 90980-11289. A corroded or damaged APPS connector is a leading cause of P2135 and P2138 throttle position sensor correlation faults — often misdiagnosed as a failed pedal assembly.
| OEM Number | Type | Application |
|---|---|---|
| 6189-0369 | Female housing (vehicle side) | Toyota / Nissan APPS harness |

| 2 | APPS2 signal (1.0–5.0V) | Green/Red | P2138 – APPS1/APPS2 correlation fault |
| 3 | APPS1 reference voltage (5V) | Pink/Black | Both signals drop to 0V; limp-home mode |
| 4 | APPS2 reference voltage (5V) | Pink/White | P2135 / P2138 / P0120 |
| 5 | APPS1 ground | Black/White | Signal offset; unstable idle |
| 6 | APPS2 ground | Black/Red | P2138; throttle stuck at partial open |

Q: My Toyota has P2135 — is it the pedal assembly or the connector?
A: P2135 on Toyota is frequently caused by a corroded 6-pin APPS connector rather than a failed pedal assembly. Before replacing the $150+ pedal, inspect the connector for green corrosion or bent pins. Clean with electrical contact cleaner and retest — if the code clears, the connector was the cause.
Q: What is the difference between 6189-0369 and 6188-0209?
A: 6189-0369 is the female housing (vehicle harness side); 6188-0209 is the male housing (sensor/pedal side). You need both to complete a connector repair.
Q: Why does my car go into limp-home mode with this fault?
A: The ECU uses two independent APPS signals (APPS1 and APPS2) as a safety redundancy. When the signals don't correlate — often due to a corroded pin on one circuit — the ECU cannot confirm driver intent and defaults to limp-home mode (typically 1,500 RPM / 20% throttle) to prevent unintended acceleration.
Q: Are terminals included?
A: Yes, terminals and wire seals are included with all variants.
