ESWW Intake Air Temperature & MAP Sensor 12681993 / 082800-0630 — Black, Direct-Fit Replacement for Chevy GMC

ESWW Intake Air Temperature and Manifold Pressure Sensor (PN 12681993 / 082800-0630) monitors intake air temperature and manifold pressure for proper engine control and diagnostics.

This ESWW replacement sensor combines intake air temperature and manifold absolute pressure (MAP) sensing in a single plug-and-play unit engineered as a direct-fit substitute for part numbers 12681993 and 082800-0630. Designed to match the electrical and mechanical fit of the original equipment, it restores airflow-related inputs to the vehicle’s engine control module so fuel and timing calculations can be made from accurate data. The sensor is molded from durable ABS, tested for fit and basic function, and supplied as a single black sensor ready for installation.

How does this sensor affect engine performance?

A functioning intake air temperature and MAP sensor gives the engine control module the pressure and temperature values it needs to estimate air mass and adjust fuel delivery and ignition timing. When the sensor provides accurate readings, the ECU can better manage air-fuel ratio and idle behavior. Faulty or missing signals can trigger diagnostic trouble codes and unpredictable running conditions.

• Measures intake manifold absolute pressure and air temperature simultaneously
• Provides digital/electrical signal compatible with OEM ECU inputs
• Helps maintain proper air-fuel calculations and engine control responsiveness

Which vehicles and part numbers is this compatible with?

This ESWW unit is manufactured to replace original part numbers 12681993 and 082800-0630 and fits a range of GM models when those numbers match. Always verify the OEM part number on your existing sensor or in the vehicle service documentation before ordering to ensure fitment. Compatibility commonly includes many Chevy and GMC models such as Silverado, Sierra, Malibu, Equinox, Cascada, and heavy-duty variants like 2500/3500 where the listed OEM numbers apply.

• Direct replacement for OEM 12681993 and 082800-0630
• Common in Chevrolet and GMC trucks and cars (Silverado, Sierra, Malibu, Equinox, Cascada)
• Verify the part number on your current sensor before purchase

What are the build quality and durability features?

The housing is molded from reinforced ABS for impact and abrasion resistance while resisting environmental exposure under the hood. Internal sensing elements and connector terminals are assembled to meet basic durability expectations for automotive replacement parts. ESWW products undergo bench verification so the unit functions electrically before shipment.

• Durable ABS housing resists wear and scratches
• Stable electrical connector for secure ECU interface
• Pre-tested for basic function and correct output ranges

How easy is installation and what does the package include?

Installation is designed to be straightforward: the sensor is a plug-and-play replacement that uses the stock electrical connector and mounting interface. Removal of the old sensor and installation of the ESWW part typically requires minimal hand tools and basic mechanical experience. The package contains one black intake pressure/temperature sensor ready to install.

• Plug-and-play electrical connector for quick swap-out
• Mounting form factor matches OEM position for straightforward fit
• Supplied as a single sensor—no extra hardware unless vehicle requires it

Who is this for: This ESWW dual-function intake air temperature and MAP sensor is intended for technicians, DIY mechanics, and fleet managers who need a cost-effective, direct-fit replacement for OEM part numbers 12681993 and 082800-0630 on compatible Chevy and GMC vehicles. It’s suitable when the original sensor shows diagnostic codes, inconsistent engine behavior, or when replacing aged components during routine maintenance. Always confirm the part number and connector style before purchasing to ensure correct application.
