GM GENUINE PARTS Intake Air Temperature Sensor 213-190 (25036751) OE-fit Accurate Response

The GM Genuine Parts 213-190 (25036751) Intake Air Temperature Sensor monitors the temperature of incoming air so your engine control module can optimize fuel and ignition settings.

This GM-recommended intake air temperature (IAT) sensor is an original-equipment replacement designed to match the fit, function and durability of the factory-installed component. Built to GM OE specifications and supplied under the GM Genuine Parts program, it reports accurate intake air temperature data to the vehicle’s engine control module to support consistent engine performance and emissions control. The part number 213-190 (25036751) is engineered specifically for compatibility with the appropriate GM models and connectors.

How does this sensor affect engine performance?

The IAT sensor provides the engine control module with the air temperature reading the vehicle needs to calculate air density and adjust fuel delivery and ignition advance. A correct signal helps the engine run smoothly across different ambient conditions and prevents rough idle or drivability issues related to incorrect air/fuel mixture. This is a monitoring component, not a control device; it supplies critical input for engine management.

• Accurate air temperature input improves fuel metering and ignition timing
• OEM calibration reduces risk of incorrect readings or compatibility errors
• Direct-fit design preserves original harness and mounting locations

What makes GM Genuine Parts 213-190 (25036751) different from aftermarket sensors?

GM Genuine Parts are manufactured to the same specifications used for factory assembly, which helps ensure the electrical characteristics, connector interface, and mechanical fit match the original. That consistency reduces installation hassle and the chance of fault codes due to mismatched sensors. The part is vetted to meet GM’s durability and environmental requirements.

• Built to GM OE tolerances for shape, mounting, and connector pinout
• Tested for temperature response and long-term stability under vehicle conditions
• Supplied through GM channels for traceability and correct application fitment

How do I install or replace the intake air temperature sensor?

Installation is straightforward for technicians or experienced DIYers: locate the sensor in the intake tract or air cleaner housing, disconnect the wiring harness, remove the retaining fastener, and swap in the new GM part. Always follow vehicle-specific service procedures, torque specifications, and safety precautions. If the vehicle shows a diagnostic trouble code, clear codes and verify operation after installation.

• Disconnect battery negative terminal before servicing electrical components
• Unplug the sensor connector and remove mounting bolt(s) or clips
• Install new sensor, secure fastener, reconnect harness, and verify system readiness

Will replacing this sensor fix a check engine light?

If diagnostic trouble codes indicate a faulty IAT sensor or you observe symptoms consistent with incorrect intake air readings, replacing the sensor can resolve those specific codes. However, a check engine light can have many causes—always scan codes first to confirm the IAT sensor is the fault. After replacement, clear stored codes and test-drive to confirm the issue is resolved.

• Useful when diagnostics identify intake air temperature circuit faults
• Not a universal cure for unrelated engine or emissions system codes
• Post-replacement verification confirms successful repair

Who is this for: Drivers and technicians who need a direct-fit, factory-spec intake air temperature sensor for compatible GM vehicles. Choose the GM Genuine Parts 213-190 (25036751) if you want an OE-quality replacement that preserves original electrical characteristics, fitment, and service life, or when vehicle diagnostics point to a malfunctioning IAT sensor.
