P0335 Jeep Patriot: Identifying and Resolving Sensor Issues – A Comprehensive Guide

Gary, from the YouTube channel Weakest of Weeks, is here to guide you through fixing a common issue in the 2011 Jeep Compass. But, as he mentions, this repair is applicable to the same platform from the years 2007 to 2017, meaning it can also work for the Jeep Patriot, Dodge Caliber, Dodge Avenger, and potentially the Dodge Journey.

The problem he’s addressing is a hard starting issue, often accompanied by a specific check engine light code. He explains that this issue can occur as these vehicles age and accumulate more miles. The culprit? The crankshaft position sensor.

Identifying the Problem

Gary explains that when the vehicle reaches operating temperature, the sensor may fail, causing the vehicle to shut off while driving or have difficulty starting. This issue is typically confirmed by a check engine light associated with the failed sensor.

To verify the problem, Gary uses a scanner and finds the specific code related to the crankshaft position sensor issue, which further confirms the diagnosis.

Replacing the Sensor

He proceeds to demonstrate the replacement process, starting with locating the sensor, which is situated behind the engine, underneath the exhaust manifold. Gary advises temporarily bending the small metal heat shield out of the way to gain access to the sensor.

He then shows how to remove the sensor, emphasizing the importance of replacing it with the original equipment manufacturer (OEM) version for long-term reliability.

Completing the Replacement

After obtaining and installing the new factory brand sensor, Gary aligns and secures the pigtail, ensuring it’s in place and won’t vibrate out. He also emphasizes the importance of ensuring that the pigtail is clipped into place in the thin metal heat shield.

Final Steps

After refastening the air duct and engine cover, Gary highlights the significance of clearing the error code, and upon starting the vehicle, confirms that the issue has been resolved.

In closing, he reiterates that this replacement process is relevant for various models under the Fiat Chrysler umbrella, beyond just the Jeep Compass and Patriot.


Gary concludes by sharing the positive outcome of the replacement, with the vehicle running as it should, without stalling or experiencing hard starting.
