Detailed Description

NTK EH0331 is part of the NTK Engine Crankshaft Position Sensor line, a product family developed from the brand’s OE sensor experience and expanded technical sensor coverage. The sensor is manufactured to meet or exceed OE specifications and is subjected to thermal shock, vibration, and OBD verification testing to support consistent signal performance.

For fitment, this sensor is listed for 2003-2005 Chevrolet Vectra and 2002-2003 Saturn Vue. The Saturn Vue application includes a note that a relearn procedure may be required, so factory service information should be checked before installation. The EH0331 part number should be matched to the vehicle’s original sensor configuration before ordering.

This part cross-references Bosch 0261210206 and Standard Ignition PC567 for the same application.

What It Is Used For

• Restoring crankshaft position signal input to the engine control system
• Addressing hard-start or no-start conditions related to crank signal loss
• Correcting intermittent stalling caused by an inaccurate crankshaft signal
• Resolving engine misfire or timing-related drivability concerns
• Replacing a failed sensor with the correct OE-style electrical layout

Installation Notes and Quality

Verify connector shape, terminal count, and sensor body diameter against the original part before installation. Follow factory service procedures for relearn or calibration steps when required by the vehicle application.
