Detailed Description

Prenco 4E-1053 is used to monitor camshaft position and send timing information to the engine control system. On supported Chevrolet Silverado 1500, GMC Sierra 1500, Chevrolet Express, GMC Savana, and related GM platforms, this sensor helps maintain accurate ignition and fuel timing when the original camshaft position sensor is worn or failing. This part cross-references AMS Automotive 6216 for the same application. Additional interchange references include 10485432 and DR188.

Compatible With 1995-2007 Chevrolet Blazer, 1996-2007 Chevrolet Express 1500, 2000-2007 Chevrolet Silverado 1500, 1996-2005 GMC Safari, and other listed GM applications. Prenco 4E-1053 also covers distributor-location applications on select 2006-2007 Chevrolet Express 2500, GMC Savana 2500, Silverado 1500 Classic, and Sierra 1500 Classic models.

What It Helps Address

• Hard starting caused by an inaccurate camshaft position signal
• Intermittent stalling or rough running from sensor signal loss
• Check engine light conditions related to camshaft position sensor faults
• Misfire or timing-related drivability complaints
• Crank/no-start concerns on listed GM ignition systems

Installation Notes and Tips

Verify the connector shape, terminal count, and mounting style before installation. This sensor uses a female oblong connector with blade terminals and an included bracket, so the mounting point and distributor-location configuration must match the vehicle application. Confirm the exact year, make, model, and engine setup against the fitment list before replacing the original part.

Quality Assurance

Prenco ignition and sensor components are cataloged for direct replacement use on the listed GM applications. Fitment is confirmed for the vehicles shown in the application data, including Chevrolet Silverado 1500, GMC Sierra 1500, and Chevrolet Express platforms.
