Give the engine control module the precise timing data it needs by replacing a worn cam signal with the NTK Engine Camshaft Position Sensor EC0230. Cataloged for the exhaust camshaft position, it installs as a direct-fit replacement for the listed applications, including the 2002-2005 Chevrolet TrailBlazer, 2004-2006 Chevrolet Colorado, 2002-2005 GMC Envoy, 2006 Hummer H3, and 2004-2007 Saturn Ion — see the Buyer's Guide tab for the full list of 17 vehicles.
- Exhaust camshaft placement: cataloged for the exhaust-camshaft position on the listed engines.
- Reports position to the ECM: monitors the rotation of the camshaft so the engine control module can time sequential fuel injection and ignition.
- Direct-fit replacement: designed to plug in on the listed applications.
Signs the original sensor may need replacing include hard starting, stalling, rough running, or a check engine light with a camshaft-position-sensor code. Diagnose the cause first; if a failed camshaft position sensor is behind the symptom, this replaces it.
