ESWW Intake Air Temperature and MAP Sensor 12681993 / 082800-0630 — Direct-Fit IAT/MAP for Chevy GMC (Plug-and-Play)

ESWW intake air temperature and manifold pressure sensor (part 12681993 / 082800-0630) is a direct-fit replacement sensor that monitors intake air temperature and manifold pressure to supply engine control systems with accurate data.

This ESWW sensor combines intake air temperature (IAT) and manifold absolute pressure (MAP) sensing in a compact, plug-and-play unit designed to replace OE parts for a range of Chevy and GMC vehicles. Built from durable ABS plastic and tested for consistent readings, the sensor provides the electrical signals your engine control module needs to adjust fuel delivery, ignition timing, and emissions strategies. Before ordering, confirm the part number and vehicle compatibility to ensure a correct fit.

How will this sensor fit my Chevy or GMC vehicle?

The ESWW unit is engineered as a direct replacement for OE part numbers 12681993 and 082800-0630, matching the original electrical connector and mounting dimensions for straightforward installation. Many Silverado, Sierra, Malibu, Equinox, Cascada, and 2500/3500-series models use this sensor location and configuration.

• Direct-fit for OE 12681993 / 082800-0630
• Compatible with select Chevy and GMC models—verify vehicle application
• Same connector layout to avoid splicing or adapter use

What does this sensor measure and why does it matter?

This combined IAT/MAP sensor measures intake air temperature and manifold pressure and sends those signals to the engine control unit. Those readings help the ECU calculate air density and load, which in turn influence fuel injection and timing strategies to maintain drivability and emissions behavior.

• Monitors intake air temperature for accurate air density calculation
• Measures manifold pressure to report engine load to the ECU
• Provides electrical output compatible with original vehicle systems

How easy is it to install and what tools are required?

The ESWW sensor is designed for simple installation: unplug the stock sensor, remove the mounting fastener, install the new sensor, and reconnect the electrical plug. Many DIYers can complete the swap with basic hand tools in a short period; no complex reprogramming is usually required.

• Plug-and-play connector—no wiring modifications expected
• Standard hand tools (ratchet, sockets, and possibly a trim tool) typically suffice
• Inspect mounting O-ring or seal and replace if worn for proper fit

What materials and quality checks support long-term use?

Manufactured from sturdy ABS plastic, the sensor housing is built to resist wear, scratches, and common under-hood conditions. ESWW performs bench testing on signal output and physical fit to ensure the replacement matches the original part’s performance profile.

• Durable ABS construction for stability and scratch resistance
• Electrical testing to validate pressure and temperature signal output
• Ships as a single black intake pressure/temperature sensor ready for installation

Who is this for: Drivers and technicians who need a reliable, cost-effective replacement for a failing or damaged intake air temperature and manifold pressure sensor on compatible Chevy and GMC models. It’s suitable for DIY mechanics replacing a known OE number and for professional shops needing a drop-in sensor that replicates original fit and function. Always confirm the vehicle’s part number and perform basic diagnosis before replacement to ensure the sensor addresses the root cause of any drivability codes.
