Walker Products Manifold Absolute Pressure (MAP) Sensors are OE Replacement components designed to measure the pressure within the intake manifold and communicate that data to the engine control module (ECM). This allows the ECM to calculate engine load and adjust fuel injection and ignition timing for optimal power output, fuel efficiency, and emissions performance. MAP sensors play a critical role in modern engine management systems and are used across gasoline and diesel platforms. Each Walker MAP Sensor is engineered to meet OE specifications for electrical output, pressure range, and connector fit, ensuring seamless integration with the vehicle’s existing system. Built to withstand high engine bay temperatures, vibration, and potential intake air contaminants, these sensors are tested for accuracy, responsiveness, and long-term reliability. Whether addressing drivability issues, check engine codes, or restoring performance, Walker Products delivers OE-level quality in every MAP Sensor replacement.
Characteristics include:
Robust Construction: Crafted with high-quality materials, these sensors are built to withstand challenging conditions, ensuring long-lasting reliability and reducing the need for frequent replacements.
Engineered for OE Performance: These sensors are meticulously engineered and rigorously tested to meet and exceed OE performance and durability standards, ensuring consistent and accurate pressure readings.
Effortless Installation: Designed for easy and straightforward installation, these sensors minimize vehicle downtime during replacement, keeping your vehicle on the road.
Accurate Pressure Sensing: Our premium MAP Sensors provide precise measurement of manifold pressure, optimizing engine performance and efficiency.
By delivering accurate pressure data, these sensors help the engine's electronic control unit (ECU) optimize the air-fuel mixture, promoting better fuel efficiency, engine performance, and reliable pressure monitoring.

Customer Reviews
Overall rating: 4.8 / 5 from 670 reviews.
Just received my front brake they look good quality.
La livraison se fait en un temps record, malheureusement il y a eu un erreur de pièce, par contre un service très professionnel, facile d'accès et dans ma langue natale..... Le retour est accepté sans frais. Tout les professionnels dans le domaines de la mécanique savent que des erreurs survient aléatoirement au niveaux pièces un jour ou l'autre, pas très agréable mais la ou ce joue la qualité du service est le service après vente et je peux confirmé la compétence de l'équipe Parts Pionner... Merci à l'équipe
Toujours en attente du ticket de retour mais j'ai confiance dans leurs bref délais...
LB Mécanique générale vous remercie et aux plaisirs de refaire affaire ensemble....!
This was my first dealing here. Easy to browse the site,the ordering process was quick and straightforward and shipping was fast and flawless. 10 out of 10.
Parts were well packaged, came with all hardware needed for clips, anti rattle clips, as well as mounting hardware. I drove the car to have the car relearn piston positioning, and these are much more grippy than factory honda/acura pads and rotors, so I am really happy with them. I am surprised it only took 3 days for them to arrive after ordering them from Calgary to sw ontario. I have already recommended part pioneer and this brand of pads and rotors to my friends.
Parts came really fast and of good quality as I’ve been a licensed mechanic for over 25 years departure just as good or better than buying in your local parts stores
