NTK EH0311 Engine Crankshaft Position Sensor

Engine Crankshaft Position Sensor Overview

NTK EH0311 is an engine crankshaft position sensor built for import and domestic applications with OE-focused engineering. It uses a rectangular female connector, blade terminals, and a compact sensor body to support accurate signal delivery in the engine management system.

Compatible with Subaru Outback, Legacy, WRX STI, Impreza, Tribeca, WRX, and B9 Tribeca applications, this sensor is part of the NTK Engine Crankshaft Position Sensor line. NTK draws on OE sensor experience and testing practices to deliver coverage for vehicles that rely on precise crankshaft position input.

Key Features

• NTK EH0311 crankshaft position sensor for engine timing signal input
• Rectangular female connector with blade terminals for direct electrical connection
• Compact 0.580 sensor body diameter for a space-conscious design
• Engineered under NTK's technical sensor program for broad aftermarket coverage
• Tested under thermal shock, vibration, and OBD verification conditions

Detailed Description

The NTK EH0311 is a crankshaft position sensor designed to report crankshaft speed and position data to the engine control system. Accurate sensor input is critical for ignition timing and fuel control, especially in Subaru applications such as the Outback, Legacy, and WRX STI. This part number, EH0311, is built to meet or exceed OE specifications and reflects NTK's role as an OE supplier with a full line of technical sensors.

The sensor features one rectangular female connector, two male blade terminals, and a 0.580-inch body diameter. The NTK Engine Crankshaft Position Sensor line is backed by the brand's OE-based development approach, with validation that includes thermal shock, vibration, and OBD checks. This makes EH0311 a direct replacement option for vehicles that require stable crankshaft signal performance.

What It Helps Address

• Hard starting caused by missing or inconsistent crankshaft signal data
• Engine stalling related to incorrect position input
• Rough running from timing and synchronization errors
• Check engine light conditions tied to crankshaft sensor faults
• Intermittent drivability issues in Subaru Outback and Legacy applications

Installation Notes and Tips

Verify connector shape, terminal count, and sensor body dimensions before installation. Confirm the application by year, make, and model, since EH0311 covers multiple Subaru platforms including Outback, Legacy, WRX STI, Impreza, Tribeca, WRX, and B9 Tribeca. The mounting bracket is not included.

Quality Assurance

NTK states that its technical sensors undergo thermal shock, vibration, and OBD verification testing and are manufactured to meet or exceed OE specifications. This part cross-references Standard Ignition PC297 for the same application.
