Standard Ignition PC1135 Engine Crankshaft Position Sensor

Engine Crankshaft Position Sensor for GM Applications

Standard Ignition PC1135 is an engine crankshaft position sensor built for accurate crankshaft signal detection and stable engine timing input. It is a direct-fit style replacement for select Buick Cascada and Chevrolet Malibu models from 2016-2019.

• Bolt-on attachment method for secure mounting
• 1 female plug-in connector with 3 male blade terminals
• 12-volt electrical design
• Integrated A/D conversion and digital signal processing for improved signal accuracy
• Adaptive switch point calibration for consistent timing output
• Shielded circuitry to help protect against electromagnetic interference and power spikes
• Performance-tested calibration for timing accuracy between the target wheel and sensor output

Fitment Details

Fits 2016-2019 Buick Cascada, N/A. Fits 2016-2019 Chevrolet Malibu, N/A.

This part cross-references Walker Products 235-1888 for the same application.

How This Sensor Works

The PC1135 monitors crankshaft position and sends a digital signal to the engine control system so ignition timing and engine management can stay synchronized. Standard Ignition calibrates the sensor during performance testing to improve timing accuracy, while environmental, endurance, and end-of-line testing helps support consistent signal quality. For Buick Cascada and Chevrolet Malibu owners diagnosing crank signal faults, this sensor addresses the electrical input the powertrain control module relies on for engine operation.

Common Issues It May Resolve

• Crankshaft position sensor fault codes
• Intermittent no-start or extended crank conditions
• Rough running caused by unstable crank signal input
• Stalling related to incorrect engine speed or timing data
• Misfire or synchronization issues tied to sensor signal loss

Installation Notes

Verify connector style, terminal count, and mounting style before installation. Clean the mounting surface and inspect the target wheel area for damage or contamination that could affect signal quality. After installation, clear diagnostic trouble codes and confirm proper engine operation with a scan tool.

Quality Assurance

Standard Ignition subjects this sensor to environmental, endurance, and end-of-line testing for timing, pulse width, and signal amplitude to support reliable operation. The sensor also uses circuitry intended to resist stray electromagnetic fields and voltage spikes.
