Product Line Overview

NTK Engine Crankshaft Position Sensor products are part of NTK’s technical sensor lineup, backed by more than 80 years of automotive experience. NTK supplies OE and aftermarket sensor coverage for import and domestic vehicles, with a focus on application-specific fit and signal accuracy. The EH0343 follows that OE-based approach for vehicles that depend on precise crankshaft position input for engine management.

Detailed Description

The NTK EH0343 crankshaft position sensor is used by the engine control system to monitor crankshaft position and rotational speed. That information supports ignition timing and fuel delivery control on vehicles such as the 2002-2006 Nissan Altima, 2002-2008 Nissan Maxima, 2003-2008 Nissan Murano, 2003-2004 Nissan Pathfinder, 2004-2006 Nissan Quest, 2003-2008 Nissan 350Z, 2003-2007 INFINITI G35, 2003-2008 INFINITI FX35, 2006-2008 INFINITI M35, and 2002-2004 INFINITI I35. This part number, EH0343, is built for direct replacement service where OE-level sensor performance is required.

This part cross-references DENSO Auto Parts 196-4012 and Standard Ignition PC499 for the same application.

What It Helps Address

• Crankshaft position signal loss
• Intermittent stalling or hard starting related to sensor input
• Check engine light concerns tied to crankshaft sensor faults
• Rough running caused by inaccurate engine speed data
• Ignition timing and fuel control errors from a failing sensor

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. The EH0343 uses a 1-connector, 3-terminal blade-style configuration with a female connector and male terminals, and it does not include a mounting bracket. Confirm the vehicle application by year, make, and model before replacing the original sensor. For Nissan Altima, Maxima, Murano, Pathfinder, Quest, and 350Z service, compare the OE connector and sensor location to ensure correct part selection.

Quality Assurance

NTK sensors are produced to meet or exceed OE specifications and are validated through thermal shock, vibration, and OBD verification testing. As part of NTK’s OE-focused sensor program, EH0343 is supported by the brand’s technical sensor expertise for import and domestic vehicle coverage.
