Standard Motor Products PC1238 Camshaft Position Sensor

The Standard Motor Products PC1238 is a direct-fit replacement camshaft position sensor (CMP sensor) engineered to restore precise engine timing and performance. Typically located in the engine's cylinder head, the camshaft position sensor determines which cylinder is firing in order to establish injector synchronization and the coil firing sequence in distributorless ignition (DIS) systems.

Key Features:

• Manufactured at an IATF 16949-certified facility to ensure consistent quality and reliability
• Each unit undergoes 48-to-64-hour vibration testing across three planes, plus end-of-line timing, pulse width, and signal amplitude testing
• Protects against over-voltage, under-voltage, reverse-voltage, and short circuits for long service life
• Advanced circuitry provides immunity from EMI, including stray electromagnetic fields, power spikes, and static electricity, meeting ISO standards
• Fluorocarbon rubber oil seal ensures a secure, leak-free fit
• Integrated waterproof connector for lasting, corrosion-resistant performance
• Engineered to meet or exceed OEM specifications for accurate, reliable, maintenance-free operation

Camshaft position sensors are highly complex components that measure the cam's relative position and rotational speed in real time — even the slightest delay or inaccuracy can affect ignition timing, fuel economy, and emissions. Trust Standard Motor Products PC1238 to restore proper engine management system function and keep your vehicle running as designed.
