Cummins 3971106 Manifold Air Pressure (MAP) Sensor 03-07 Dodge 5.9L Cummins
Description
The MAP sensor on your Cummins is responsible for telling the ECM the density of air getting to the cylinders. If this sensor is reading incorrectly, the ECM will not be able to accurately tell the injectors how and when to fire, causing poor engine performance. This is a genuine Cummins replacement MAP sensor to get you back on the road reliably.

About WrenchConnected
WrenchConnected is an independent installation marketplace operating in partnership with Diesel Power Products.
How it works
After checkout, we route your vehicle info and part SKU to verified installation shops near you. Local installers review the job and submit competitive bids; you pick the shop you want based on price, reviews, and availability. Your name and email stay private until you select an installer.
Pricing
You pay for the bid from your preferred shop. The full amount is shown before you confirm — installers cannot add charges without your written consent. Payments are processed securely by Stripe.
Your privacy
During bidding, shops see only your service ZIP code, vehicle year/make/model, and the part SKU — not your name, email, or address. Only the shop you select receives your contact details after payment. We never sell your personal information.

About Cummins
While we are obvious supporters of the aftermarket, there are times when it does make the most sense to stick with factory Cummins components for various upgrades or repairs. While we do not carry every component, we do stock items that we feel are a good choice when making the decision to go stock or aftermarket.

Genuine
"I bought a "Cummins" sensor from another dealer and I'm sure it was a fake. Came in a plain white box marked made in USA. Only the box was made in USA. The sensor was Chinese crap. This sensor from DPP is a genuine Cummins sensor no doubt. Thanks DPP for not being a pack of lying, thieving scumbags."
