Standard Motor Products PC978 Camshaft Position Sensor

The Standard Motor Products PC978 Camshaft Position Sensor is a precision-engineered component designed to monitor camshaft position and rotational speed in real-time. Typically located in the engine's cylinder head, this sensor determines which cylinder is firing to establish proper injector synchronization and coil firing sequence in distributorless ignition systems.

Key Features:

• Advanced circuitry provides immunity from electromagnetic interference (EMI) including stray electro-magnetic fields, power spikes, and static electricity, meeting ISO standards
• Built-in protection against over-voltage, under-voltage, reverse-voltage, and short circuits
• Maintains accuracy during heavy-duty shock, vibration, and maximum temperature conditions
• Fluorocarbon rubber oil seal ensures secure fit and lasting performance
• Integrated waterproof connector for durability in harsh engine environments
• Manufactured at IATF 16949-certified facility with rigorous quality control

Quality Assurance:

• Undergoes extensive 48-to-64-hour vibration testing across three different planes
• End-of-line timing, pulse width, and signal amplitude testing ensures proper performance
• Engineered for accuracy, speed, and durability to help maintain optimal engine performance

This camshaft position sensor is part of Standard Motor Products' comprehensive sensor program, which features nearly 1,000 SKUs covering more than 250 million vehicles. The sensor works in conjunction with the engine control module to regulate ignition timing, fuel delivery, and overall engine performance. When a camshaft sensor fails, it can cause engine misfires, reduced fuel economy, rough idling, or difficulty starting.
