Manifold Absolute Pressure (MAP) Sensor Chevrolet Uplander 3.5L 2005-2009 Location and Replacement

Searching for the exact location of the Manifold Absolute Pressure (MAP) Sensor on a 2005–2009 Chevrolet Uplander 3.5L? In this video, I focus entirely on pointing out its precise position on the engine’s intake manifold assembly, saving you the major headache of hunting around blindly through a crowded engine bay or chasing down the wrong electrical connectors.

If you are gearing up for a DIY MAP sensor replacement or cleaning a contaminated sensor on your Chevy Uplander minivan, getting a clear visual on the exact layout beforehand is half the battle. Knowing precisely where the sensor lives allows you to map out your approach under the cowl, see how the locking tabs and vacuum seals release, saves you valuable time, and keeps you from getting frustrated before you even begin working.

⚠️ Symptoms of a Faulty Manifold Absolute Pressure (MAP) Sensor:

You are likely inspecting or searching for this component if your 3.5L V6 engine is showing any of these common air-fuel ratio, ignition, or drivability failure signs:

• An active Check Engine Light lit constant on your dashboard (frequently pulling diagnostic codes like P0106, P0107, or P0108)
• Severe engine stumbling, hesitation, or a sluggish response when you press down on the gas pedal to accelerate
• A rough, unstable, or shaking idle when stopped at a red light, sometimes leading to the engine stalling out completely
• Black smoke coming from the tailpipe or a strong smell of unburnt fuel due to the computer running an overly rich fuel mixture
• A noticeable drop in overall fuel economy as the engine management system fails to accurately calculate engine load and air density

🛠️ Safety First!

Working around automotive engines, intake systems, and electrical harnesses requires extreme caution. Please prioritize your safety before performing any hands-on inspection or work. Always disconnect the negative battery cable first to protect the vehicle’s sensitive electronic control modules. Never forcefully pry on old, heat-brittle plastic locking clips or sensor bodies, as breaking the mounting boss on the intake manifold can lead to a much more complicated and expensive repair. Wear high-quality safety glasses and durable mechanic gloves to protect your eyes and hands from sharp metal brackets, tight engine bay spaces, and engine grime. Stay alert, be attentive, and keep your workspace safe!
