Component Location
A quick and direct guide showing you the exact location of the Powertrain Control Module (PCM) on a 2011-2020 Dodge Journey equipped with the 3.6L Pentastar V6 engine (Note: The 3.6L engine option was introduced to the Journey lineup starting in the 2011 model year). No wasted time, no endless talking—just a clear view of where to find it securely mounted inside the driver’s side front fender well, positioned right in front of the front tire and tucked behind the plastic splash shield assembly.

This video is designed to save you time and frustration before you even pull off the front wheel, making your DIY auto repair much smoother.
Common Bad Symptoms
When this component begins to fail, you might experience several warning signs. Common symptoms of a faulty Powertrain Control Module include random engine stalling or dropping into a restricted “limp mode,” an intermittent or complete no-crank/no-start condition, or a persistent check engine light (CEL) accompanied by multiple unrelated sensor codes or communication error codes (such as U0100). You might also experience erratic automatic transmission shifting, a sudden drop in fuel economy, or completely dead diagnostic communication at the OBD-II port under the dash.
Safety First!
Before you start working on your vehicle, always prioritize safety. Because this is the primary computer managing your vehicle’s entire electrical architecture, you must completely disconnect the negative battery cable before unplugging the PCM connectors to avoid static discharge, short circuits, or permanent data corruption. Always use heavy-duty jack stands to securely support the vehicle after lifting it to remove the wheel, wear proper eye protection and mechanics’ gloves, and ensure your working environment is safe before performing any vehicle maintenance.
