Walker 235-2411 Engine Camshaft Position Sensor

Engine Camshaft Position Sensor Overview

Walker 235-2411 is a standard replacement engine camshaft position sensor for applications that need accurate camshaft timing data. It uses Hall Effect or magnetic induction technology to send precise signals to the engine control module for synchronized valve operation and fuel injection.

Compatible with a wide range of GM and related applications, this sensor supports smoother idle quality, cleaner emissions, and consistent engine response. The Walker 235-2411 is built for direct sensor replacement where the original unit has failed or is no longer reading correctly.

Key Features

• Standard replacement camshaft position sensor
• Hall Effect or magnetic induction sensing technology
• Precise camshaft speed and position signal output
• Female connector with oblong shape
• Spade terminals with 2- or 3-wire configurations
• Walker 235-2411 part number for fitment lookup

Detailed Description

This camshaft position sensor monitors camshaft position and speed so the engine control module can coordinate ignition and fuel delivery. The result is accurate timing input for engines that rely on stable sensor feedback to maintain drivability and emissions performance. Walker 235-2411 is a practical replacement choice for vehicles such as the Buick Rainier, Chevrolet Trailblazer, GMC Envoy, and Oldsmobile Bravada, among others listed in the fitment data.

Walker Products uses sensor technology intended for dependable signal accuracy under demanding operating conditions. If you are replacing a failing camshaft sensor on a Chevrolet Trailblazer, GMC Envoy, or Pontiac Grand Am application, this part number provides a direct reference for the correct sensor style and connector configuration.

What It Is Used For

• Restoring camshaft position signal accuracy after sensor failure
• Addressing rough idle caused by incorrect timing input
• Correcting hard-start or intermittent stalling conditions tied to sensor output
• Supporting proper fuel injection synchronization
• Reducing emissions issues related to inaccurate camshaft data

Installation Notes and Tips

Verify connector shape, terminal count, and wire configuration before installation. This part uses an oblong female connector with spade terminals and 2- or 3-wire layouts, so matching the original connector style is important. Confirm the application by year, make, and model before ordering Walker 235-2411.

Quality Assurance

Walker Products positions this sensor as a standard replacement component built for accurate signal delivery and consistent operation. The 235-2411 is specified for multiple vehicle applications, including Buick Rainier, Chevrolet Trailblazer, and GMC Envoy fitments.
