Awasome 2012 Jeep Patriot Check Engine Light Reset References. I have a 2013 patriot with 24,000 miles on it. You can find out the trouble code causing your problem by inserting the key into the ignition and turning it to the on position.

Web in this guide, we cover the meaning of the check engine light on jeep vehicles. Web if your jeep patriot has a flashing check engine light means that there is a catalyst damaging misfire (it can damage the catalytic converter and o2 sensors). I checked my gascap and it wouldn’t tighten at all, so i bought a new one and replaced it.
