3-Pin Knock / Camshaft / Crankshaft Sensor Connector | Type A & B Female OEM
This 3-pin female connector is used in knock sensor (KS), camshaft position sensor (CMP), and crankshaft position sensor (CKP) harnesses. Available in Type A and Type B housing configurations to match different OEM sensor connector designs, bare or with 15cm pre-wired leads. The 3-pin configuration serves sensor power, ground, and signal circuits.

A 3-pin knock/CMP/CKP sensor connector serves: sensor power supply (+5V reference), sensor ground, and sensor signal output. The signal circuit transmits the sensor pulse or voltage to the ECU for ignition timing control (knock sensor), valve timing (CMP), or fuel injection synchronization (CKP). A corroded connector on any pin causes knock sensor faults (P0325–P0334), CMP faults (P0340–P0349), or CKP faults (P0335–P0339).
Knock, CMP, and CKP 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 engine knock retard, ignition timing faults, misfires, and no-start conditions. Replacing the connector restores clean sensor signal continuity.
Compare the housing shape and locking tab of your existing OEM sensor connector to select Type A or B.
Q: What fault codes indicate a failed knock/CMP/CKP connector?
A: Common codes include P0325–P0334 (knock sensor circuit), P0335–P0339 (CKP sensor circuit), P0340–P0349 (CMP sensor circuit), P0300–P0308 (engine misfire), and no-start conditions.
Q: How do I identify Type A vs Type B?
A: Compare the housing body shape and locking tab position of your existing OEM sensor connector with the product images for each type.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
