Standard Ignition PC4 Engine Camshaft Position Sensor

Engine Camshaft Position Sensor for GM Applications

Standard Ignition PC4 is an engine camshaft position sensor built for accurate timing signal delivery in select Buick, Oldsmobile, and Pontiac applications. It uses integrated digital signal processing and a dynamically adaptive switch point to improve signal accuracy, while protected circuitry helps guard against electromagnetic interference and power spikes.

Key Features

• Female connector with 3 male blade terminals
• Integrated A/D converter and digital signal processing for precise output
• Adaptive switch point for improved timing accuracy
• Shielded circuitry to resist stray electromagnetic fields and voltage spikes
• Custom magnetic circuit calibration for consistent target wheel signal timing
• Environmental, endurance, and end-of-line testing for timing, pulse width, and signal amplitude

Detailed Description

The Standard Ignition PC4 camshaft position sensor is engineered to deliver stable camshaft timing feedback to the engine control system. By refining the signal at the sensor level, it supports accurate synchronization between the target wheel and sensor output on vehicles such as the Buick Century, Buick LeSabre, and Oldsmobile Cutlass Ciera. This part number, PC4, is also listed for Buick Riviera, Oldsmobile 98, Oldsmobile Toronado, Oldsmobile Delta 88, Oldsmobile Cutlass Cruiser, and Pontiac Bonneville applications within the confirmed fitment range.

This part cross-references Spectra Premium S10118 for the same application.

What It Helps Address

• Camshaft position signal loss or erratic sensor output
• Hard starting caused by incorrect timing input to the engine computer
• Intermittent stalling related to unstable cam signal data
• Check engine light concerns tied to camshaft position sensor faults
• Driveability issues from inaccurate timing synchronization

Installation Notes and Tips

Verify connector style, terminal count, and fitment before installation. Standard Ignition PC4 uses a female connector with 3 male blade terminals, so matching the electrical connection is important for proper operation. Confirm the vehicle application by year and model, especially on 1986-1988 Buick Century, 1986-1988 Buick LeSabre, and 1986-1987 Buick Riviera listings.
