Cj7jeepoffroad Posted September 30, 2018 Share Posted September 30, 2018 Hello this is my first post, i have a 2014 MKZ 3.7 V6, I’m having a problem with the fuel economy meter being maxed out all the time (as if the car was under acceleration or going up a hill) the average is showing correctly (about 9.5L/100KM) but the instant gauge that is suppose to fluctuate based on throttle or load is maxed at 30L/100km. I did notice the other day as I was sitting in a parking lot with the car running that the meter was bouncing up and down randomly. Has anyone seen this issue? Thanks Quote Link to comment Share on other sites More sharing options...
drolds1 Posted October 1, 2018 Share Posted October 1, 2018 Welcome to the forums. There was a TSB for this for certain 2014s. The IC needs to be reprogrammed. Quote Link to comment Share on other sites More sharing options...

drolds1 Posted October 5, 2018 Share Posted October 5, 2018 Did you click on the hot link I provided above? It's TSB 14-0016. Quote Link to comment Share on other sites More sharing options...
RAB Posted November 3, 2018 Share Posted November 3, 2018 The first time I reported that problem with my 2014 MKZ to my dealer I told them, "I think there is a TSB about that." They "reset the gauge" with the "OK" button on the steering wheel which, of course, didn't fix it. My next maintenance visit I reported the problem again and gave the service rep a piece of paper with "TSB 14-0116 Fuel Economy Gauge/Bar Stuck" written on it. She didn't type that in the service order, but she did attach my note to the order. The tech performed the TSB and my gauge has been fine ever since. My car was still under warranty at the time, so I don't know if or what they would have charged to apply the TSB otherwise. My notes say TSB 14-0116, which I got from Alldatadiy, not 14-0016 as droids mentioned. I don't know which of us has a typo. Quote Link to comment Share on other sites More sharing options...
Mcondo Posted November 4, 2018 Share Posted November 4, 2018 I have a 2014 3.7 and I don't have any kind of economy gauge that i can see. Just avg mpg when I click fuel economy. Weird. Quote Link to comment Share on other sites More sharing options...

The fuel economy gauge (below the trip odometers in the menu) should have a horizontal line showing the average fuel economy, and a vertical bar graph that constantly moves up and down showing your instant fuel economy. The TSB solves the problem if that vertical instant economy bar disappears. Quote Link to comment Share on other sites More sharing options...
