Charge Air Temp Sensor - Mopar (05149279AC)

Use For 04/11/2018 And After. Intake Air Temperature Sensor. For Vehicles Built After 12-07-2013.

This Genuine Mopar Charge Air Temperature (CAT) Sensor (05149279AC) is the precision "brain" of your intake system, responsible for delivering real-time air density data to your Engine Control Module. While "budget" sensors often use slow-reacting thermistors that lead to sluggish acceleration, this authentic OEM sensor is calibrated for the high-speed data processing required to optimize ignition timing and fuel injection.

The Advantage That Sets You Apart

• Rapid Thermal Response: Engineered with a high-sensitivity sensing element that detects micro-changes in air temperature instantly. This prevents the "lag" found in aftermarket sensors, ensuring your engine adjusts fuel trim perfectly as you climb grades or enter boost.
• Precision-Tuned Resistance Curve: Unlike universal sensors that can "drift" and trigger false Check Engine lights, this Mopar part is factory-mapped to your vehicle's specific voltage tables. It ensures your air-to-fuel ratio remains at the "Goldilocks" zone for both power and efficiency.
• Contaminant-Resistant Housing: Designed to live in the harsh, oily environment of a turbocharged or supercharged intake tract. The sensor body is constructed from high-grade polymers that resist "heat soak" and chemical degradation, preventing the internal shorts common in unbranded electronics.
• Gold-Plated Electrical Terminals: Features corrosion-resistant connector pins that maintain a low-resistance signal path. This eliminates the "electrical noise" and intermittent signals that cause erratic idling and "stumbling" under load.
• Mopar Certified Protection: Backed by a Mopar 2-year/Unlimited Mile Warranty, providing a level of professional accountability and nationwide dealership support that online-only "white-label" brands simply cannot offer.
