ESWW Intake Air Temp & MAP Sensor Part 12681993/082800-0630 — Direct-Fit for Chevy GMC Silverado Sierra

ESWW intake air temperature and manifold pressure sensor (part 12681993 / 082800-0630) measures intake air temperature and manifold absolute pressure to give the engine control unit accurate data for engine management.

This ESWW replacement MAP and intake air temperature sensor is engineered as a direct-fit alternative for select Chevy and GMC models including Silverado, Sierra, Malibu, Equinox, Cascada and 2500/3500 series trucks. Built from durable ABS and tested to match OE signal characteristics, it restores the sensor inputs the engine control module needs to calculate fuel delivery and ignition timing. The sensor plugs into the original connector and mounts in the intake manifold, offering an affordable, ready-to-install option when the factory sensor fails or shows diagnostic trouble codes.

How will this sensor affect engine performance and diagnostics?

Replacing a faulty MAP/intake air temperature sensor with this ESWW unit provides the engine control unit with accurate pressure and temperature readings, which helps the ECU make appropriate fueling and timing adjustments. While it does not change power by itself, correct sensor data reduces engine hesitation, rough idle, and false diagnostic codes related to the intake system.

• Delivers manifold absolute pressure (MAP) and intake air temperature signals to the ECU
• Helps the vehicle’s computer calculate air density for proper fuel metering
• Can clear or prevent engine codes tied to incorrect intake readings

Is this ESWW sensor compatible with my Chevy or GMC model?

This sensor is designed as a replacement for vehicles that list part numbers 12681993 or 082800-0630. It is commonly used across multiple Chevy and GMC platforms, but you should always confirm cross-reference numbers and VIN-fitment to ensure compatibility. Using the original part number or consulting a dealer fitment guide is recommended before ordering.

• Replaces OE part numbers 12681993 and 082800-0630
• Typically fits Silverado, Sierra, Malibu, Equinox, Cascada and 2500/3500 models
• Verify vehicle year, engine code, and part number for exact fit

How easy is installation and what should I expect during replacement?

The ESWW manifold pressure and intake air temperature sensor is built for plug-and-play installation with the factory harness and mounting location. Most replacements require basic hand tools, and the procedure usually involves removing an intake cover, unplugging the old sensor, and securing the replacement in the manifold. After installation, allow the vehicle to run through a few key cycles so the ECU can recalibrate.

• Simple electrical connector and direct-fit mounting design
• No specialized tools required for standard installations
• Allow the ECU to relearn after installation for best results

What are the sensor’s build quality and durability features?

Made from high-quality ABS, the ESWW sensor is built to resist wear, scratches and common under-hood conditions. It is manufactured and tested to provide stable signal output across typical operating temperatures and pressure ranges encountered in intake manifolds. While not an OEM-branded sensor, it’s engineered to match the performance characteristics of the original component.

• Durable ABS housing resists vibration and environmental wear
• Factory-style electrical connector and signal response
• Tested to provide consistent pressure and temperature data

Who is this for: This ESWW intake air temperature and manifold pressure sensor is intended for DIY mechanics, independent repair shops, and fleet managers who need an economical, direct-fit replacement part for compatible Chevy and GMC vehicles. Choose this sensor if you have verified the OE part number (12681993 / 082800-0630), are experiencing intake-related diagnostic codes, or need to restore correct intake air temperature and pressure readings to the engine control unit.
