Let me know what engine came in this and I'll tell you which fuse to check for the speed sensor and/or the speedometer/transmission. Also, if it's 2wd, 4wd or awd.
If it's the 2.2, check the ECM/Trans fuse 43 in the underhood fuse block next to the left strut tower.
If the 2.4, same fuse.
You may also want to check the ECM/TCM fuse 25 in the body control module (BCM) located below the radio.
The BCM is (UNDER CENTER DASH, BELOW RADIO, ON RIGHT SIDE OF CENTER CONSOLE)
You should be checking fuses with a voltmeter or at least a 12 volt test light cause a lot of times another fuse may feed a fuse or in this case fuse 43 isn't hot until the key is on run/start so it's probably fed by the ignition switch. Also test both sides of the fuse, that way you can test both that the fuse isn't blown and plus that it has voltage to it, and turn the key on if it is usually hot with key on.
Actually 43 is fed from a relay.
Here are the wiring diagrams in case we need them anymore,
here, this diagram shows the bcm,
Find it yet?
ok, if that fuse 43 has no voltage with the key on run, replace that "Run/Crank" relay in the underhood fuse block and try it again.
