Jeep Cherokee MAP Sensor Guide for 2013-2021 Models
Understand, diagnose, and replace the MAP sensor on your 2013-2021 Jeep Cherokee.
- A bad MAP sensor on a Jeep Cherokee often causes a check engine light, poor fuel economy, rough idle, and hesitation.
- Common trouble codes include P0106, P0107, and P0108.
- Replacement is simple for DIYers, involving a twist-lock sensor on the intake manifold.
- Aftermarket sensors are a cost-effective option, but OEM Mopar parts are often recommended by owners for reliability.
Symptoms of a Failing MAP Sensor
When the MAP sensor in your Cherokee starts to fail, the engine's computer gets bad information, which can cause a variety of problems. The most obvious sign is the Check Engine Light coming on. You may also notice your engine running poorly. This can include a rough or unsteady idle, hesitation when you accelerate, and a general loss of power. Some owners report stalling, where the engine shuts off unexpectedly. Another common symptom is a drop in fuel economy, meaning you'll be filling up the gas tank more often. In some cases, you might even see black smoke coming from the exhaust, which is a sign of unburnt fuel.

Symptoms of a bad MAP sensor can be similar to other problems, like vacuum leaks from a cracked hose. Before replacing the sensor, it's a good idea to check for any obvious air leaks in the intake system, as this can also cause MAP sensor error codes.
Choosing an Aftermarket MAP Sensor
When replacing your MAP sensor, you have a choice between an original equipment manufacturer (OEM) part from Mopar and an aftermarket part. OEM sensors are made by the vehicle's manufacturer and are guaranteed to fit and perform to the original specifications. However, they are usually the most expensive option.
Aftermarket parts, like those from the "Replacement" brand, are a more affordable choice. These parts are designed to function as a direct replacement for the original sensor. While many aftermarket sensors work well, quality can sometimes vary between brands. For a critical component like a MAP sensor, some Jeep owners prefer to stick with OEM to avoid potential issues. However, if budget is a primary concern, an aftermarket sensor with a good warranty can be a practical solution.
Reset the Computer
After installing a new MAP sensor, it's a good practice to clear any stored trouble codes from the engine computer. You can do this with an OBD2 scanner or by disconnecting the battery for about 15 minutes. This allows the computer to recalibrate with the new sensor's readings.
Installation Overview
Replacing the MAP sensor on a 2013-2021 Jeep Cherokee is a relatively simple job that most DIYers can handle. The sensor is located on the intake manifold. On the 3.2L V6 engine, it's on the top, behind the throttle body. On the 2.4L engine, it's on the side of the intake manifold and may be easier to access from underneath the vehicle. The sensor is typically held in place by a simple twist-lock mechanism, not bolts. To replace it, you disconnect the electrical connector, rotate the sensor about 90-100 degrees, and pull it straight out. Installation is the reverse of removal.
