YUEQING QIYE AUTO PARTS delivers reliable‑connector‑to‑harness connection solutions. Featuring superior terminal crimping performance and high‑temperature endurance, our products are perfectly suited for engine wiring harness assembly.
Designed for Engine Sensor Applications
ECU Signal Interface
Crankshaft sensor connectors feature low contact resistance and stable electrical contact. Resistant to engine‑bay vibration, temperature cycling and contamination, they preserve signal integrity between sensors and the ECU. This prevents intermittent faults in engine timing control and maintains consistent electrical connection between sensors and vehicle wiring harnesses.
Sealed Connector Design
The sealed connector structure shields the electrical mating interface from moisture, dust and external contaminants, preventing unstable signals caused by corrosion under harsh engine‑bay conditions.
Temperature Resistance
Selected YUEQING QIYE AUTO PARTS crankshaft sensor connectors operate within a temperature range of -40℃ to 120℃.
Secure Terminal Retention
Equipped with CPA / TPA secondary locking mechanism, it achieves secure terminal retention. It resists continuous vibration and mechanical shocks generated during engine operation, eliminating risks of terminal loosening and back‑out. Terminals remain properly positioned inside the connector housing to maintain stable electrical contact.
Compact Sensor Interface
Compact housing design saves installation space in the cramped engine bay. The streamlined profile enables reliable signal connection between crankshaft sensors and wiring harnesses without compromising sealing performance, vibration resistance or electrical integrity. It is ideal for sensor harness applications with limited mounting space.
How to Choose the Right Crankshaft Sensor Connector
You need to confirm the following information:
- Confirm OEM Part Number

Frequently Asked Questions About Automotive Crankshaft Sensor Connector
A crankshaft sensor connector is an automotive electrical connector that connects the crankshaft position sensor (CKP sensor) to the vehicle wiring harness and engine control unit (ECU/ECM). It provides the electrical connection required to transmit crankshaft position and speed signals from the sensor to the engine control system.
The crankshaft sensor connector itself does not detect crankshaft movement. The crankshaft position sensor measures the position and rotational speed of the crankshaft, while the connector provides a stable electrical interface for power supply, signal transmission, and sensor grounding.
A crankshaft position sensor connector is used to provide a reliable electrical connection between the crankshaft position sensor (CKP sensor) and the vehicle wiring harness or engine control unit (ECU/ECM).
Its main function is to transmit crankshaft position and engine speed signals from the CKP sensor to the ECU, allowing the engine control system to accurately control ignition timing, fuel injection timing, and engine synchronization.
The connector itself does not measure crankshaft position. The crankshaft position sensor detects crankshaft movement, while the connector provides the electrical pathway for signal transmission.
YUEQING QIYE AUTO PARTS CVCONNECTOR provides crankshaft sensor connectors designed for automotive engine management applications, including connector assemblies for crankshaft position sensors (CKP sensors), wiring harness applications, and engine compartment electrical systems.
Available crankshaft sensor connector solutions can include different connector configurations based on vehicle application requirements, such as:
Different pin configurations
Different housing designs
Different terminal specifications
Different sealing structures
Customized connector solutions according to customer drawings or OEM requirements
YUEQING QIYE AUTO PARTScrankshaft sensor connectors are developed to support reliable electrical connections in automotive environments where vibration, temperature variation, moisture, and contamination resistance are required.
Yes, YUEQING QIYE AUTO PARTS CVCONNECTOR provides crankshaft sensor connectors with different pin configurations, including 2-pin and 3-pin designs for automotive crankshaft position sensor (CKP sensor) applications.
The correct pin configuration depends on the sensor type, vehicle application, and electrical circuit design.
2-pin crankshaft sensor connectors are commonly used for variable reluctance (VR) crankshaft position sensors, where the connector typically carries differential signal circuits.
3-pin crankshaft sensor connectors are commonly used for Hall-effect crankshaft position sensors, where the connector typically includes power supply, ground, and signal circuits.
The connector pin count alone does not determine compatibility. The connector interface, pin assignment, terminal specification, locking structure, and vehicle application should also be confirmed.
Yes, YUEQING QIYE AUTO PARTS CVCONNECTOR provides sealed crankshaft sensor connectors designed for automotive engine compartment applications where protection against moisture, dust, oil, and environmental contaminants is required.
Sealed crankshaft sensor connectors use protective structures such as wire seals, interface seals, and secure locking mechanisms to help maintain reliable electrical connections under harsh vehicle operating conditions.
The sealing design helps reduce the risk of:
Water intrusion
Dust contamination
Terminal corrosion
Electrical signal instability
Connector performance degradation
Yes, YUEQING QIYE AUTO PARTS CVCONNECTOR can help match crankshaft sensor connectors based on OEM part numbers, vehicle application information, connector samples, or technical drawings。
The OEM part number is an important reference for identifying the correct crankshaft position sensor connector because it helps confirm the required:
Connector housing design
Pin configuration
Terminal type
Locking structure
Mating interface
Wiring requirements
However, OEM part number matching should be verified together with the actual connector specifications to ensure mechanical and electrical compatibility
Yes, you can send a connector photo to YUEQING QIYE AUTO PARTS CVCONNECTOR for identification and compatibility evaluation.
