danskidoo Posted February 24, 2009 Posted February 24, 2009 Hello everyone this is my first post and i wanted to see if anyone has any ideals. This morning i was driving to work and noticed my current mpg was at 16 then it jumped up to 44 then down to 3 and all the way up to 99, it's just bouncing all over. All the other display options are working fine. I think the electrical connection might have come loose or the sensor went bad. My guess is there's a sensor on the intake manifold that sends the data to the computer. i haven't had a chance to look yet, it's been rainy. Does anyone have an ideal if there is such a sensor and where it is? thanks Dan
blake918 Posted February 25, 2009 Posted February 25, 2009 There is nothing wrong with your car; current = your mpg updated every 2 seconds. As long as your tank average and average aren't jumping around, your car is fine.
amcdonal86 Posted February 25, 2009 Posted February 25, 2009 Dang it. I wish I had gotten a UCF20 II. :(
danskidoo Posted February 25, 2009 Author Posted February 25, 2009 I've owned the car for 4 years now and it's never done this. At a constent speed on the freeway and at idle the display bounces around all over the place. It's not normal that's why i'm asking everyone on the forum. As far as the tank average being correct im not sure because the problem started this morning.
mebush Posted February 25, 2009 Posted February 25, 2009 Blake918 is right--the current mpg function bounces all over the place because it is not any kind of average. It is the MPG at that second. It may seem pretty constant if you were driving on a really flat road with the cruise on but say you are traveling at highway speed down a hill--let completely off the gas and it will shoot up to 99.9. Accelerate up the next hill it may read 4.

SKperformance Posted February 26, 2009 Posted February 26, 2009 Need to see what it is using to evalutate the display. it take load so it may be a throttle position issue or pedal position issue. need to have a scan tool to display the readings.
