2.5 rpms stay high while switching gears, doesnt when speed sensor disconnected
I just bought the truck last week to get back and forth to work. When I got it the speedometer/wiper/domelight fuse was missing. When I put it in everything worked including the speedo, however with the fuse in when i shift gears the rpms stay very high and dont come down until I stop. Is this a defective speed sensor or abs speed sensor? Any help would be great! I wouldn't mind no speedo but the wipers are on same fuse

Re: 2.5 rpms stay high while switching gears, doesnt when speed sensor disconnected
Define very high rpm. 1, 100-1,500 is normal because the ecu is rpm matching for an expected gear change.

I dont have a tach so I dont know exactly, id guess 3500. Its definitely not normal, when that speedo fuse is taken out its normal thata why I'm guessing I just need a speed sensor. It also idles pretty rough but doesnt have any cels

Check the idle air control, also try disconnecting the ground to the battery and re setting the comp.

I replaced iac and reset ecu. It didnt help. Only thing that has helped is taking out speedo fuse
