Ford 4-Pin Waterproof Sensor Wire Harness Connector – Female OEM

This 4-pin waterproof female connector is used in Ford sensor harnesses including MAP sensors, MAF sensors, throttle position sensors, and other 4-wire sensor circuits. Sealed nylon housing with IP67-equivalent waterproofing ensures reliable sensor signal continuity in underhood environments. Available bare or with 15cm pre-wired leads.

Key Specifications

Why Sensor Connectors Fail

Ford sensor connectors in underhood environments are exposed to heat, vibration, and moisture. Terminal corrosion or housing damage causes intermittent sensor signal faults, triggering P-codes for MAP (P0105–P0108), MAF (P0100–P0104), or TPS (P0120–P0124) circuits. Replacing the connector restores clean sensor signal continuity and eliminates ghost fault codes.

Variant Guide

• Female – Bare 4-pin housing with terminals
• Female 15CM – Pre-wired with 15cm leads for direct splice-in installation

Installation Steps

1. Disconnect the vehicle battery
2. Locate the 4-pin sensor connector on the MAP, MAF, or TPS harness
3. Release the locking tab and unplug the original connector
4. Transfer terminals to the new housing or splice in the pre-wired variant
5. Reconnect and clear sensor fault codes with a scan tool

Frequently Asked Questions

Q: What Ford models use this 4-pin sensor connector?
A: This connector is used on Ford Focus, Fiesta, Mondeo, Escape, Fusion, F-150, and Transit with 4-wire sensor harnesses. Cross-reference your vehicle’s wiring diagram to confirm fitment.

Q: What fault codes indicate a failed sensor connector?
A: Common codes include P0100–P0108 (MAF/MAP sensor circuit), P0120–P0124 (TPS circuit), and P0340–P0345 (CMP sensor circuit) on Ford platforms.

Q: Is this waterproof?
A: Yes. The sealed housing provides IP67-equivalent moisture protection suitable for underhood sensor environments.

Q: Are terminals included?
