Good morning. I recently purchased a 2003 Rubicon 500FA knowing the shift angle sensor might be bad. I replaced the sensor but it still gives me the same issue. The sensor calibrates (or at least it sounds like it does) and then when I start it back up everything looks normal. But, as soon as I put it into gear, the transmission indicator starts flashing again and I only have first gear. Also, I cannot get the machine to go into diagnostic mode to see if there are any codes in they system. Any ideas on what to look for?

 

Check the gear switch in rear of engine ohm out each gear position

 

thanks for the lead. sure enough, i got waaaaayy too much resistance when its in drive. gonna swap the sensor and hopefully that does it.

 

Any updates?

 

As a matter of fact, yes. I was finally able to get to it late last week. Apparently someone had spliced two of the wires together for the transmission position sensor. I'm going to try to attach a picture here so you can see the handiwork that I discovered. I don't understand why someone would do this, but once I replace the sensor, everything worked out just fine. Even gave it a quick test run through the woods this weekend

 

WOW Thats great you found it I am like you dont understand some people....... Ride and enjoy

 

Much appreciated the direction on this.

 

Your much welcome
