6-Pin 3.5mm Accelerator Pedal Sensor Connector OEM 936394-2 / 1928404629 – Fiat / Alfa Romeo / Hyundai / Kia / Smart
Direct OEM-specification replacement for the TE Connectivity / Bosch 6-pin 3.5mm waterproof connector used on electronic accelerator pedal position sensors (APPS) across Fiat, Alfa Romeo, Hyundai, Kia, and Smart platforms. Cross-references OEM numbers 936394-2 (TE Connectivity housing) and 1928404629 / 1 928 404 629 (Bosch cross-reference). A corroded or damaged APPS connector is a leading cause of P2135 and P2138 throttle position correlation faults — frequently misdiagnosed as a failed pedal assembly costing $100–$300.
| OEM Number | Manufacturer | Application |
|---|---|---|
| 936394-2 | TE Connectivity (AMP) | 6-pin 3.5mm APPS connector housing – primary |
| 1928404629 | Bosch cross-reference | Same connector – Bosch catalog format |
| 1 928 404 629 | Bosch (spaced format) | Same as 1928404629 |
| Pin | Function | Typical Wire Color | Failure Symptom if Open/Corroded |
|---|---|---|---|
| 1 | APPS1 signal (0.5–2.5V) | Green/White | P2135 – TPS1/TPS2 correlation fault; limp-home |
| 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; engine stall risk |
| 4 | APPS2 reference voltage (5V) | Pink/White | P0120 / P0220 – TPS circuit malfunction |
| 5 | APPS1 ground | Black/White | Signal offset; unstable idle / hesitation |
| 6 | APPS2 ground | Black/Red | P2138; throttle stuck at partial open |

Q: My Fiat has P2135 and goes into limp-home mode — is it the pedal or the connector?
A: P2135 on Fiat/Alfa is frequently caused by a corroded 6-pin APPS connector rather than a failed pedal assembly. The ECU monitors two independent APPS signals — when they don’t correlate due to a corroded pin, it triggers limp-home mode as a safety measure. Inspect the 936394-2 connector before replacing the $150–$300 pedal assembly.
Q: What is the difference between 936394-2 and 1928404629?
A: 936394-2 is the TE Connectivity housing part number; 1928404629 is the Bosch cross-reference catalog number for the same connector. They refer to the identical housing — different catalog systems use different numbering conventions for the same physical part.
Q: Are terminals included?
A: Yes, terminals and wire seals are included with all variants.
