Honda K24 Crank Angle Sensor (CAS) Connector – 3-Pin (Top & Bottom Keyway Options)

OEM-Style 3-Pin K24 CAS Connector – Crank Angle Sensor Plug

The Honda K24 Crank Angle Sensor (CAS) 3-Pin Connector is an OEM-style replacement plug designed specifically for K24 crank angle sensor applications. This connector is critical for proper crank signal synchronization and ignition timing accuracy in K-series engines. Available in both top-keyway and bottom-keyway configurations, this plug ensures correct fitment depending on engine variant. It is not interchangeable with the standard black 3-pin MAP/TPS sensor connector. Ideal for K-swap harness builds, engine repairs, and standalone ECU installations.

Important: Not the Standard 3-Pin K-Series Sensor Plug

This CAS connector is not the common black 3-pin MAP / TPS / cam sensor plug.

While visually similar, the keyway and indexing differ. Attempting to use the incorrect connector may result in improper locking or sensor misalignment.

Please confirm keyway orientation using the provided rear-facing installation reference photos before purchase.

Common Applications

This connector is used on:

• Honda K24 engines

• Select K24A / K24A2 variants

• K-swap builds utilizing K24 crank angle sensors

• Custom standalone ECU conversions

• Engine harness rebuilds and repairs

Proper crank angle sensor wiring is essential for ignition timing accuracy, fuel synchronization, and stable engine operation.

Designed for Professional Harness Construction

• Accepts 22–20 AWG terminals

• Includes matched wire seals

• OEM-style locking mechanism

• Available in both top and bottom keyway styles

• Designed for engine bay heat and vibration environments

These are the same quality-grade connector systems used in professional engine harness fabrication.

Available Options

Select the correct configuration:

• Top Keyway Style

• Bottom Keyway Style

Each version is photographed from the rear orientation (as installed on engine) for accurate identification.

What’s Included

• 1× 3-Pin CAS Connector Housing (Selected Keyway)

• 3× Terminals (22–20 AWG compatible)

• 3× Wire Seals

Installation Notes

Professional open-barrel crimping tools are required. Correct keyway selection is critical to ensure proper sensor engagement.

Improper crank signal wiring may result in no-start conditions, synchronization faults, or ECU trigger errors.

For proper signal integrity, we recommend using MIL-DTL-27500 Spec 55 shielded cable for crank and cam circuits.

FAQ

Is this the same as the K-Series MAP or TPS connector?
No. The K24 CAS connector uses a different keyway and is not interchangeable with standard black 3-pin K-series sensor connectors.
