Standard Motor Products AX634 Engine Intake Manifold Air Temperature Sensor 2-Terminal

The Standard Motor Products AX634 is a direct-fit replacement engine intake manifold air temperature (IAT/MAT) sensor designed to restore accurate air charge temperature monitoring to your vehicle's engine management system. This 2-terminal sensor plugs directly into the factory connector for a straightforward, no-hassle installation.

The intake manifold temperature sensor provides the powertrain control module (PCM) with real-time air density data, which the computer uses to precisely trim the air/fuel ratio for optimal combustion efficiency, fuel economy, and emissions performance. A faulty or failed sensor can result in poor fuel economy, rough idle, hesitation, and an illuminated Check Engine light.

Key Features:

• Direct-fit OE replacement — designed to match original equipment form, fit, and function
• 2-terminal connector — plugs directly into the factory wiring harness
• Tight-tolerance thermistor — precisely calibrated response values ensure accurate temperature measurement and proper PCM operation
• Resistance-welded thermistor leads — primary wire leads welded to connector terminals for a reliable electrical connection under high vibration and temperature cycling
• 100% factory tested — every unit is tested before leaving the facility to ensure trouble-free performance out of the box
• High-grade materials — built for prolonged service life and superior performance in demanding underhood environments
