Key Takeaways
  • Check for the 2005 model TSB where wiper linkage can damage MAP sensor wiring before buying a new part.
  • For reliability, choose a premium aftermarket brand like Delphi or NGK, or the OEM Mopar part.
  • Replacing the MAP sensor is a simple, 30-minute DIY job that can save you on labor costs.
  • A bad MAP sensor will cause a rich or lean fuel mixture, hurting both performance and fuel economy.
The Manifold Absolute Pressure (MAP) sensor is a key part of your Dodge Magnum's engine management system. It constantly measures the pressure inside the engine's intake manifold. This tells the main computer (ECU) how hard the engine is working. Based on the MAP sensor's readings, the computer adjusts how much fuel to inject and when to create a spark for the best power and fuel efficiency. It is a small but vital sensor for keeping your Magnum's engine running smoothly.

Is Your Magnum Running Rough? It Could Be the MAP Sensor

If your Dodge Magnum is idling poorly, getting bad gas mileage, or hesitating when you step on the gas, a failing Manifold Absolute Pressure (MAP) sensor could be the culprit. This sensor provides critical data to your engine's computer. When it fails, it can cause a variety of noticeable problems, often triggering the Check Engine Light on your dashboard.

Known Issue: Wiper Linkage Wiring Problem

For the 2005 Dodge Magnum, a Technical Service Bulletin (TSB) was issued for an issue where the wiper linkage could rub against and damage the MAP sensor's wiring. Before replacing the sensor, inspect the wires leading to it for any signs of damage, especially near the wiper assembly. A simple wiring repair might solve your problem without needing a new sensor.

Choosing the Right Aftermarket MAP Sensor

When it comes to electronic sensors, quality matters. A cheap, poorly made sensor can fail quickly or provide inaccurate readings, leaving you with the same problems. Here’s a breakdown of available aftermarket brands to help you choose.

Premium Aftermarket Brands: Best Quality

These brands are known for making parts that meet or exceed original equipment (OE) specifications. They are your best bet for a long-lasting, reliable repair, second only to the dealer part.

  • Mopar: This is the original factory part for your Dodge. It offers a guaranteed fit and the longest service life, but it is also the most expensive option.
  • Delphi: A major manufacturer of original parts for many car companies. Delphi sensors are widely considered a top-tier choice that is very close to OEM quality.
  • NGK (NTK): Known for quality ignition parts and sensors, NTK (the sensor division of NGK) is often recommended by mechanics as a reliable alternative to Mopar.

Standard Aftermarket Brands: Good Value

These brands offer a good balance of price and quality. They are a dependable choice for most owners who want a solid repair without the premium price tag.

  • Standard Ignition (SMP): A long-standing aftermarket brand that offers decent quality parts. While their quality can sometimes be inconsistent compared to their past reputation, they are generally a safe and reliable choice.
  • Walker Products: A well-known aftermarket manufacturer that produces a wide range of engine management parts.
  • Spectra: Another established brand offering a variety of automotive parts, including reliable engine sensors.

Economy Brands: Budget-Friendly

These brands are the most affordable but may have a shorter lifespan and less consistent quality. They can be an option if budget is your primary concern.

  • Crown Automotive: Forum discussions show mixed reviews for Crown's electronic parts. While some have success, others report parts being out of specification.
  • Global Parts / Holstein: These brands typically fall into the value category, offering a low-cost alternative for repairs.

Pro Tip: For a critical sensor like the MAP, spending a little more on a premium or standard brand can save you from having to do the job again in the near future. Inaccurate sensor readings can also lead to poor fuel economy, costing you more in the long run.

Cost to Replace a Dodge Magnum MAP Sensor

The cost depends on the part you choose and whether you do the work yourself. This is a very DIY-friendly repair.

Part / Service Estimated Cost
New OEM (Mopar) Part $60 - $115
New Aftermarket Part $30 - $130
Shop Labor $60 - $90
Total Professional Replacement $90 - $225
