6-Pin Waterproof Accelerator Throttle Pedal Sensor Connector – 1-2141325-1 / 1-1670919-1

Direct-fit replacement for TE Connectivity part numbers 1-2141325-1 (female housing) and 1-1670919-1 (terminal), a 6-pin IP68 waterproof connector used for accelerator pedal position sensor (APPS) and electronic throttle control (ETC) harness connections. The dual-redundant 6-pin design provides two independent signal channels for safety-critical throttle-by-wire systems.

Accelerator Pedal Sensor Pin Assignment (6-Pin Dual-Channel)

Why Throttle Pedal Sensors Use 6 Pins (Dual-Channel Safety Design)

Electronic throttle control (ETC / drive-by-wire) systems use two independent signal channels in the accelerator pedal sensor as a safety requirement. The ECU continuously compares Channel 1 and Channel 2 signals – if they diverge beyond a threshold, the ECU triggers a throttle fault and enters limp mode. This dual-redundancy prevents unintended acceleration from a single sensor failure. A corroded or open-circuit connector on either channel will trigger a throttle fault code.

Diagnosis – Throttle Pedal Faults

• P2135 (Throttle/Pedal Position Sensor Voltage Correlation): The most common code for this connector – caused by a corroded terminal creating a voltage offset between Channel 1 and Channel 2
• P0120–P0123 / P0220–P0223 (TPS/APPS Circuit): Check connector before replacing pedal assembly – a faulty 1-2141325-1 connector is a common root cause
• Limp mode / reduced power: ECU detects channel mismatch and limits throttle to 20–30% as a safety measure – inspect connector first before replacing the pedal sensor

FAQ

Q: Is 1-2141325-1 the same as 1-1670919-1?
A: No – 1-2141325-1 is the female housing; 1-1670919-1 is the terminal (contact) that inserts into the housing. Both are required for a complete connector assembly.

Q: Why does my car go into limp mode after replacing the throttle pedal connector?
A: Limp mode after connector replacement is usually caused by a terminal not fully seated (partial insertion), a damaged wire seal, or a crimping error on one of the 6 pins. Inspect all 6 terminals for full insertion and correct crimp before clearing fault codes.
