Pressure Sensor Transducer - Mopar (4799758AF)
Transmission Temperature Thermister. Line Pressure.
Pressure Sensor Transducer – Mopar (4799758AF)
The Pressure Sensor Transducer – Mopar (4799758AF) is a genuine OEM electronic sensor designed to accurately convert pressure readings into electrical signals for the vehicle’s engine management or emissions control systems. This transducer plays a critical role in providing real-time pressure data to the engine control module (ECM), allowing precise regulation of fuel delivery, boost control, and emissions-related functions.
Manufactured to Mopar’s strict factory specifications, this pressure sensor transducer features high-quality internal electronics housed in a durable, heat-resistant casing. OEM calibration ensures accurate signal output across the full operating range, even under demanding conditions such as high temperatures, vibration, and continuous system cycling. This level of precision is essential for maintaining optimal engine performance and preventing false readings that can trigger fault codes.
The Pressure Sensor Transducer – Mopar (4799758AF) is designed as a direct-fit replacement for the original factory-installed component. For professional technicians, this ensures predictable installation and seamless integration with existing wiring harnesses and control modules. For experienced DIY mechanics, OEM fitment eliminates compatibility concerns and helps restore factory-correct system operation without recalibration issues.
A failing or inaccurate pressure sensor transducer can result in reduced engine efficiency, poor throttle response, improper boost or fuel control, increased emissions, or check engine warnings. Replacing it with a genuine Mopar transducer restores accurate pressure monitoring and protects related systems from operating outside their intended parameters.
• Genuine Mopar OEM pressure sensor transducer built to factory standards
• Accurately converts pressure readings into ECM-ready signals
• Durable construction resistant to heat, vibration, and environmental exposure
• Helps prevent drivability issues and emissions-related fault codes
• Direct-fit design for reliable installation and system compatibility
• Ideal for professional diagnostics, repairs, and quality DIY maintenance
Choosing the Pressure Sensor Transducer – Mopar (4799758AF) ensures precise system feedback, dependable engine control, and long-term reliability consistent with original factory performance.
