Standard Ignition PC274 Engine Crankshaft Position Sensor

Engine Crankshaft Position Sensor for 1998-1999 P30 and P3500

Standard Ignition PC274 is an engine crankshaft position sensor built for direct replacement on select Chevrolet P30 and GMC P3500 applications. It uses a bolt-on mounting style with a 3-pin female oval connector for straightforward OE-style service.

Key Features

• Bolt-on attachment method for secure mounting
• Female oval connector with plug-in connection
• 3-terminal design with male pins and female plug terminals
• Integrated A/D conversion and digital signal processing for accurate output
• Adaptive switch point calibration for consistent timing signal response
• Protected circuitry helps resist stray electromagnetic fields and power spikes
• Performance-tested for timing, pulse width, and signal amplitude consistency

Detailed Description

Standard Ignition PC274 is engineered to monitor crankshaft position and deliver the timing signal the engine control system relies on for ignition and fuel management. The sensor’s internal signal processing and calibrated magnetic circuit help maintain accurate communication between the target wheel and sensor output. This makes PC274 a practical replacement choice for 1998-1999 Chevrolet P30 and 1998-1999 GMC P3500 vehicles when restoring crank signal integrity.

This part cross-references Delphi SS11396 for the same application. The PC274 part number is also commonly searched by technicians and parts buyers looking for an engine crankshaft position sensor for Chevrolet P30 and GMC P3500 service work.

What It Helps Solve

• Crankshaft position signal loss
• Intermittent no-start conditions related to crank signal failure
• Rough running caused by inaccurate engine timing input
• Stalling tied to unstable sensor output
• Check engine light concerns related to crankshaft position sensor faults

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. Clean the mounting surface and inspect the target wheel for damage or contamination that could affect signal quality. Confirm the vehicle application matches the listed fitment for 1998-1999 Chevrolet P30 and 1998-1999 GMC P3500 before replacing the sensor.

Quality Assurance

Standard Ignition states that this sensor is subjected to environmental, endurance, and end-of-line testing for timing, pulse width, and signal amplitude. The manufacturer also notes controlled quality checks throughout production, from component selection to finished product.
