A-Premium MAP Sensor Replacement for Chevrolet & GMC — Direct-Fit, OEM-Style (Single)

A-Premium Manifold Absolute Pressure (MAP) Sensor — a direct-fit replacement that restores accurate manifold pressure readings for compatible Chevrolet, GMC, Buick and Cadillac engines.

When a MAP sensor fails, engine performance, fuel trim and idle stability can be affected. The A-Premium MAP Sensor is built to meet or surpass original equipment standards and ships with a one-year quality guarantee. It arrives as a single-piece, plug-in unit with a three-blade male terminal and female connector housing designed to match factory wiring and mounting points for many GM models.

How do I know this MAP sensor will fit my vehicle?

Compatibility is based on OEM reference numbers 55583389 and F01R00E033 and on specific model-year engine applications. The listing covers a broad set of Chevrolet, GMC, Buick and Cadillac vehicles—check your vehicle’s year, make and engine size against the fitment list to confirm fit before ordering.

• Fits many Chevrolet models including Camaro, Colorado, Cruze, Equinox, Impala, Silverado 1500 and Traverse (see year/engine details).
• Covers GMC models such as Acadia, Canyon, Sierra 1500 and Terrain for listed years.
• Includes Buick and Cadillac fitments like Enclave, LaCrosse, ATS, CTS and XTS across the specified years and engine sizes.
• Reference OEM numbers 55583389 and F01R00E033 for cross-checking compatibility.

What are the electrical and mechanical specifications I should expect?

This MAP sensor is supplied as a single-piece assembly with a female plug-in connector and a three-blade male terminal configuration. That connector and terminal arrangement is engineered to mirror the factory sensor for a straightforward swap without rewiring.

• Connector: female, plug-in style for one harness connection.
• Terminals: three male blade contacts to match the original sensor pins.
• Quantity: sold individually — one sensor per purchase.
• Meets or exceeds OEM manufacturing tolerances for fit and electrical function.

How will replacing this MAP sensor affect performance and maintenance?

Replacing a faulty MAP sensor can help restore engine control module inputs for air pressure, which contributes to improved fuel trim and smoother idle behavior. While results vary by vehicle and condition, installing a properly functioning sensor returns the engine management system to expected input accuracy.

• Restores accurate manifold pressure input to the engine control module.
• Can reduce rough idle, poor fuel economy and drivability issues tied to a bad MAP reading.
• Direct-fit design minimizes installation time and error risk.
• Backed by a one-year quality guarantee for manufacturing defects.

Is installation difficult and what should I check before buying?

Installation is typically straightforward for anyone comfortable with basic engine-bay work: unplug the old sensor, remove its fasteners, swap in the new unit and reconnect the harness. Before ordering, verify the OEM reference number, confirm your model-year and engine code, and inspect the wiring harness for damage to ensure a clean swap.

• Tools usually required: basic hand tools to remove mounting fasteners and a connector release tool if equipped.
• Confirm part reference numbers 55583389 or F01R00E033 on your existing sensor when possible.
• Inspect harness and connector for corrosion or damage; replace harness if terminals are compromised.
• Clear engine codes after installation and perform a test drive to verify normal operation.

Who is this for: technicians, DIY mechanics and fleet maintenance managers who need a reliable, OEM-compatible MAP sensor for a range of GM vehicles. If you own or service the listed Chevrolet, GMC, Buick or Cadillac models and need a direct replacement that matches factory terminals and fitment, the A-Premium MAP Sensor is engineered for a quick swap and dependable operation, backed by a one-year quality guarantee.
