3-Pin Camshaft & Crankshaft Position Sensor Connector – White, Black & Grey, Male & Female OEM

This 3-pin connector is used in camshaft position sensor (CMP) and crankshaft position sensor (CKP) harnesses across multiple automotive brands. Available in White, Black, and Grey housing colors, Male and Female variants, bare or with 15cm pre-wired leads. The 3-pin configuration serves sensor power (+5V or +12V), ground, and signal circuits for the CMP/CKP sensor.

Key Specifications

CMP & CKP Sensor Connector Pin Functions

A 3-pin CMP/CKP sensor connector serves: sensor power supply (+5V reference or +12V), sensor ground, and sensor signal output. The signal circuit transmits the Hall-effect or variable reluctance sensor pulse to the ECU for ignition timing and fuel injection synchronization. A corroded connector on any pin causes CMP faults (P0340–P0349) or CKP faults (P0335–P0339), engine misfires, and no-start conditions.

Why CMP/CKP Connectors Fail

Camshaft and crankshaft sensor connectors are mounted near the engine block, exposed to oil contamination, heat, and vibration. Terminal corrosion or housing damage causes intermittent sensor signal loss, triggering P0335–P0339 (CKP circuit), P0340–P0349 (CMP circuit), engine misfires (P030x), and no-start conditions. Replacing the connector restores clean sensor signal continuity.

Select the color and gender matching your OEM CMP/CKP sensor connector.

Installation Steps

1. Disconnect the vehicle battery
2. Locate the 3-pin CMP or CKP sensor connector on the engine 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 CMP/CKP fault codes with a scan tool

Frequently Asked Questions

Q: What fault codes indicate a failed CMP or CKP connector?
A: Common codes include P0335–P0339 (crankshaft position sensor circuit), P0340–P0349 (camshaft position sensor circuit), P0300–P0308 (engine misfire), and no-start conditions.

Q: How do I identify which color I need?
A: Match the housing color of your existing OEM CMP/CKP sensor connector. White, Black, and Grey variants have the same pin layout but different housing colors for circuit identification.

Q: Are terminals included?
A: Yes, terminals are included with all variants.
