Last week driving on the new Jersey turnpike at about 70 mph I had suddenly out of no were experience a little nightmare my compass lost acceleration and a strange symbol along with the traction symbol appeared on my dashboard I had later learned that one symbol was 2 lightning rods with a character in the middle so after getting the compass towed and checked by a friend with a code reader we found out the there was an error code of a u1407 so we proceeded to do some research and gathered enough information to determine that we had a throttle body issue so with a little more home work we decided to purchase the throttle body from Amazon for about $89 but we also thought it would be a good idea to replace the air filter and the spark plugs as well and to my excitement cause I love my Jeep everything worked great so my advice to everyone periodically check your air filter they say every 10.000 miles cause this might of contribute to my problem as I neglected this important part of maintenance have had the car for 2 years and this was the first time I replaced it, I know stupid me but on the brite side u saved $900 on repairs cause I did it my self so bottom line, u1407 90% on a 2016 compass the throttle body but keep in mind replace spark plugs and air as well.
