Chrysler Voyager Manifold Absolute Pressure (MAP) Sensor Guide (1994-2004)
Diagnose and replace the MAP sensor on your Voyager to fix poor engine performance and bad fuel economy.
- A bad MAP sensor causes poor fuel economy, rough idle, hesitation, and stalling.
- Always confirm the failure with an OBD-II scan; look for codes P0107 or P0108.
- Replacement is extremely easy and can be done in under 15 minutes with basic tools.
- For best results, choose a premium aftermarket brand like Delphi, NGK, or Standard Motor Products over budget options.
Is Your Voyager Running Rough? It Could Be the MAP Sensor.
A failing Manifold Absolute Pressure (MAP) sensor can cause a variety of engine problems that are often frustrating for owners. Because the sensor provides critical data for fuel and timing calculations, a bad signal can make your van run poorly. Symptoms can appear suddenly and may mimic other issues, but they often point back to this small, simple sensor.
Symptoms of a Failing MAP Sensor
- Poor Fuel Economy: If the sensor incorrectly tells the computer the engine is under high load, the PCM will inject more fuel than necessary, causing your MPG to drop.
- Lack of Power & Hesitation: If the sensor sends a signal indicating a lower load than is actually present, the computer will reduce fuel, leaving the engine feeling weak and slow to accelerate.
- Rough Idle: An incorrect air-fuel mixture from a bad MAP sensor reading often leads to a shaky or unstable idle.
- Stalling: In more severe cases, the engine may stall shortly after starting or when coming to a stop because the air-fuel ratio is too far out of balance.
- Black Smoke from Exhaust: This is a sign of a rich fuel condition, where too much fuel is being burned. A faulty MAP sensor can cause this by sending a false high-load signal.
- Check Engine Light: A failing MAP sensor will almost always trigger a Check Engine Light, with specific codes pointing to the sensor circuit. 🎬 Watch: A visual guide to bad MAP sensor symptoms
Check for Codes First
Before replacing any parts, use an OBD-II scanner to check for diagnostic trouble codes. The most common codes for a bad MAP sensor on a Chrysler Voyager are:
- P0107: Manifold Absolute Pressure/Barometric Pressure Circuit Low Input
- P0108: Manifold Absolute Pressure/Barometric Pressure Circuit High Input
These codes strongly indicate a problem with the MAP sensor or its wiring.

While an OEM Mopar part is always an option, quality aftermarket sensors can offer reliable performance at a better price. For a critical sensor like this, it's best to avoid the cheapest, no-name options. Stick with reputable brands known for their electronics.
- Premium Aftermarket (Recommended): Brands like Delphi, NGK (NTK), and Standard Motor Products (SMP) are well-regarded in the industry. Delphi was a major OEM supplier for General Motors and other carmakers, and their parts are known for quality. NGK, famous for spark plugs, also produces high-quality sensors under their NTK branding. Standard Motor Products is a long-standing, trusted name in aftermarket electronics. These brands are your best bet for a reliable, long-lasting repair.
- Standard Aftermarket: Brands like Spectra, Walker Products, and Holstein offer a balance of price and quality. They are generally considered a step up from generic parts and can be a good choice for a budget-conscious repair.
- Budget Brands: While brands like Global Parts, True Tech, and other low-cost options are available, their quality and longevity can be inconsistent. For a sensor that directly controls your engine's performance and fuel economy, spending a little more on a reputable brand is a wise investment.

DIY is Easy for This Job
The MAP sensor on most 1994-2004 Voyagers is located on the intake manifold and is held in by a single bolt or a simple twist-lock mechanism. It is easily accessible. Disconnect the electrical plug, remove the bolt or twist the sensor, and pull it out. The entire job takes less than 15 minutes with basic tools, making it an excellent DIY repair to save on labor costs.
Frequently Asked Questions
Where is the MAP sensor located on my 1994-2004 Chrysler Voyager?
The MAP sensor is almost always mounted directly on the engine's intake manifold. Look for a small, black plastic sensor with a 3-wire electrical connector, typically near the throttle body.
🎬 Watch: How to locate and remove your MAP sensorCan I just clean my MAP sensor?
While some people attempt to clean MAP sensors with electronics cleaner, it is generally not effective for a failed sensor. The failure is usually electronic and internal. Given the low cost of a new part and the importance of its function, replacement is the only reliable solution.
Are there any recalls for the Voyager MAP sensor?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls or widespread technical service bulletins (TSBs) for MAP sensor failure on the 1994-2004 Chrysler Voyager. Failures are typically due to age and normal wear.
Is an OEM Mopar sensor better than aftermarket?
An OEM Mopar sensor guarantees a perfect fit and original performance. However, for this specific part, a premium aftermarket sensor from a brand like Delphi, NGK/NTK, or Standard Motor Products will provide comparable quality and reliability for less money. Avoid the cheapest options, as their quality control can be questionable.
