URO GM1422457 Manifold Absolute Pressure (MAP) Sensor

The URO GM1422457 is a replacement Manifold Absolute Pressure (MAP) Sensor designed to meet or exceed original equipment manufacturer specifications. This direct-fit sensor restores accurate intake manifold pressure readings, helping your engine control module (ECM) deliver proper fuel and ignition timing across all operating conditions.

How It Works:

The MAP sensor measures the absolute pressure inside the intake manifold, which varies with engine load and throttle position. The ECM uses this data — along with inputs from other sensors — to calculate the correct air/fuel mixture and ignition timing. A failed or degraded MAP sensor can trigger a check engine light and cause symptoms such as rough idle, engine hesitation, poor fuel economy, or a rich/lean fuel condition.

Key Features:

• Meets or exceeds OEM specifications for accurate pressure measurement
• Direct plug-and-play replacement — no modification required
• Manufactured by URO Parts (A.P.A. Industries), a trusted supplier of quality replacement components
• Backed by URO's 24-month unlimited mileage warranty against defects in materials and workmanship
• New unit — not remanufactured

Replacing a faulty MAP sensor with this URO unit helps restore engine efficiency, smooth idle, and proper emissions output. Ideal for both professional technicians and experienced DIY mechanics.
