Walker 235-91333 Engine Camshaft Position Sensor - Intake

Walker Camshaft Position Sensor for Intake Applications

Walker Products Part Number 235-91333 is an engine camshaft position sensor for intake-side applications on select Chevrolet Colorado, GMC Canyon, Hummer H3, and Isuzu i-350/i-370 models. It provides the camshaft position and speed data the engine control module uses to coordinate valve timing and fuel delivery.

Built with a 3-terminal blade connection, oblong connector shape, and a male connector with a mounting bracket included, this sensor is a direct-fit service part for vehicles that need accurate camshaft signal input. Walker Full Service Kit coverage supports repair work on the listed intake applications.

Detailed Description

Walker 235-91333 is engineered to monitor camshaft position and rotational speed so the ECM can maintain proper synchronization between valve operation and fuel injection. That signal accuracy matters on vehicles such as the Chevrolet Colorado and GMC Canyon, where stable camshaft input supports consistent engine control. The same applies to Hummer H3 and Isuzu i-350/i-370 intake applications listed in the fitment data.

The Walker Full Service Kit line focuses on service-ready sensor coverage for common ignition and engine management repairs. This part number, 235-91333, is built for intake-position applications and uses a compact electrical interface that matches the listed connector and terminal specifications.

What It Helps Address

• Camshaft signal loss or erratic camshaft position readings
• Hard starting caused by incorrect engine timing input
• Rough idle from inconsistent sensor feedback
• Check engine light conditions related to camshaft position sensor faults
• Fuel injection timing issues tied to inaccurate camshaft data

Installation Notes and Tips

Verify the intake position, connector style, and terminal count before installation. Confirm the vehicle application against the fitment list for 2004-2007 Chevrolet Colorado, 2004-2007 GMC Canyon, 2006-2007 Hummer H3, 2007 Isuzu i-370, and 2006 Isuzu i-350. Inspect the harness connector for corrosion, bent terminals, or damaged locking features before connecting the new sensor.

For best results, clear any stored diagnostic trouble codes after installation and confirm that the engine starts, idles, and responds normally. This part cross-references Standard Motor Products (e.g., PC853, PC854) for the same application.

Quality Assurance

Walker Products positions this camshaft position sensor as a service part built for accurate signal tracking and durable operation in demanding engine environments. The design supports consistent ECM input for the listed intake applications, including Chevrolet Colorado, GMC Canyon, and Hummer H3 fitments.
