2010 Jeep Wrangler 3.8L v6 - Starts then immediately stalls. Usually takes multiple attempts to start and run normally. Produces NO ERROR Codes.

Put in the new sensor last night. Will have to wait and see if the problem occurs again. If not, I believe we can assume the sensor was the problem. I will post an update if the problem persists, or an update in 3 months if it has not reoccurred. Best wishes, and thank you for the timely response.

what sensor did you change that fixed the problem?

Changed the transmission position sensor. Seemed to do the job, but about 30 days ether problem returned. After researching more, I found a YouTube video of someone who had the same problem. It turned out to be the security system had lost the programming for one of the two keys we owned. Because ithe car doesn’t sense a valid key, it shuts the engine down. To check it this is your problem also, put key in ignition, turn to rn position (all dash sensors on) but do not turn to start. You will notice a small red light on the right side of the instrument cluster. It will go out. If it comes back on and flashes, it is not sensing your key. If it stays off, turn the starter over and car will run. If that’s what you experience, try your spare key. Or visit your dealer to reprogram. Hope that helps.
