Standard Ignition PC1137 Engine Camshaft Position Sensor

Engine Camshaft Position Sensor for Buick and Chevrolet

Standard Ignition PC1137 is an engine camshaft position sensor built for accurate cam timing signal input on select Buick and Chevrolet applications. It uses integrated A/D conversion and digital signal processing to improve signal consistency, while adaptive switching helps maintain accurate operation.

Key Features

• Plug-in connector design with 3 male blade terminals
• Integrated A/D converter and digital signal processing for refined signal output
• Dynamically adaptive switch point for improved timing accuracy
• Electromagnetic field and power spike protection built into the circuitry
• Custom magnetic circuit programming calibrated during performance testing
• 100% environmental, endurance, and end-of-line testing for timing, pulse width, and signal amplitude

Detailed Description

This Standard Ignition camshaft position sensor, part number PC1137, is engineered to deliver stable camshaft position feedback for engine management systems. It is used on 2016-2018 Chevrolet Malibu, 2016-2018 Buick Cascada, and 2019 Buick Cascada applications, with 2019 Buick Cascada requiring programming for installation. The sensor’s calibrated magnetic circuit and signal processing help maintain accurate timing between the target wheel and sensor output, supporting consistent engine control performance.

This part cross-references Walker Products 235-1889 for the same application.

What It Helps Solve

• Camshaft position signal loss or erratic sensor output
• Check engine light concerns related to cam sensor performance
• Hard starting or extended crank conditions tied to timing input errors
• Rough running caused by inconsistent camshaft signal data
• Intermittent drivability issues from electrical noise or voltage spikes

Installation Notes and Tips

PC1137 uses a plug-in connection with male blade terminals, so verify connector style and terminal count before installation. On 2019 Buick Cascada applications, programming is required after installation. Confirm the vehicle year and model match the listed fitment before replacing the sensor.

Quality Assurance

Standard Ignition subjects this sensor to environmental, endurance, and end-of-line testing to verify timing, pulse width, and signal amplitude. That testing process supports consistent output and reliable operation across the listed Buick and Chevrolet applications.
