Product Line Details

NTK’s technical sensor line expands the brand’s OE-focused coverage for import and domestic vehicles. Backed by more than 80 years of automotive experience, NTK applies OE development knowledge to aftermarket sensors for consistent signal accuracy and application-specific fitment. The EH0404 follows that approach for crankshaft position sensing in select Chevrolet Colorado, GMC Canyon, and Hummer H3 applications.

Detailed Description

The EH0404 crankshaft position sensor monitors crankshaft rotation and sends the signal the engine control system uses for ignition timing and fuel strategy. When the sensor signal becomes weak or inconsistent, drivability and starting performance can suffer. This NTK replacement is engineered for the listed applications and uses the connector and terminal layout required for proper integration. This part cross-references Standard Ignition PC556 for the same application.

Common Issues This Part May Address

• Hard starting or extended crank time
• Intermittent stalling or sudden engine shutdown
• Misfire codes related to crankshaft position signal loss
• Rough idle or unstable engine operation
• No-start conditions caused by an inaccurate crank signal
