Standard Motor Products PC346 Camshaft Position Sensor

The Standard Motor Products PC346 is a direct-fit replacement camshaft position sensor (CMP sensor) engineered to restore precise engine timing and reliable performance. OEM cross-reference part number: 12141247258.

What It Does:

The camshaft position sensor monitors the rotational position of the camshaft and continuously transmits that data to the vehicle's Engine Control Module (ECM/PCM). This real-time signal is critical for sequential fuel injection timing, ignition timing, cylinder-specific knock control, and the trigger signal for pump-valve injection systems. Even minor inaccuracies from a failing sensor can negatively impact engine performance, fuel economy, and emissions.

Key Features:

• Exceeds OEM specifications for accurate, reliable, maintenance-free operation
• Custom magnetic circuit programming calibrates the sensor during performance testing to improve timing accuracy between the target wheel and sensor output
• Integrated A/D converter with digital signal processing and a dynamically adaptive switch point for improved accuracy and real-time data delivery to the PCM
• Advanced circuitry provides immunity from stray electromagnetic fields and power spikes
• High-strength neodymium magnet ensures proper signal voltage output to the ECM
• Watertight connector seals out moisture; sealed metal case prevents oil intrusion
• 100% environmental, endurance, and end-of-line tested for Timing, Pulse Width, and Signal Amplitude to ensure consistent reliability
• Vibration tested for up to 68 hours and chamber tested from -40°F to 257°F for performance in extreme conditions
