if i remember correctly they did not start using an electronic speedometer in f150's till 1992 so your vehicle should still have a mechanical speedometer which has a cable ran down to your transmission. the sensor on the rear differential on those models is an abs sensor on 92 and later its the abs and speed sensor.
The speedometer is wired to a VSS. If it has failed then the unit will need to be replaced. Odometer and trip meter are wired into the same fuse and should be checked. If the fuse is blown the odometers will not work.
check the wiring to the speedometer. Check the sending unit as well. If the problem is internal then the speedometer will have to be replaced.
If it's an analog speedometer, first check the condition of the speedometer cable. It may need to be replaced.
Is the TCM working normally and throwing no codes?
Needs new speed sensor or if it has a cable to the speedometer it needs to be replaced along with the housing.
It is either the speed sensor or the wiring. Have it checked out.
Speed sensor. There is not a cable on this car.
May have replaced the wrong sensor or you have a bad wire in that curcuit. gm Jim
You should have your rotors checked and possibly turned or replaced as necessary You should have your rotors checked and possibly turned or replaced as necessary
Helo my name is erik, My truck is a 1992 f250 I have the same problem. I put in a new sensor and pigtail in rear and it still is not working. I have checked and removed and replaced fuses and still no go. I am going to check the wiring for continuity, and voltage. I pulled the speedo cluster out and checked it and the speedo worked for a while and quit again. I have a friend at fords and he thinks it is the wiring from the rear axle sensor to speedo or the speedometer itself. I am looking for a speedometer cluster to borrow to try that. Should be a diesel cluster. let me know if you get yours working and what you did. Thanks. Mail me at firstname.lastname@example.org
check if it has a speedometer cable if not the speed sensor needs to be replaced
Since you replaced the sensor, and the speedometer still isn't working it is possible that you will need to replace the speedometer cable. Check the cable first to be sure that it is still properly connected, and if so replace the cable to see if that solves the problem.
you replaced speedo, so try replacing speed sensor
If the speedometer continues to work - probably a broken gear etc. in speedometer head and probably will have to be replaced. If speedometer does not work -- probably a broken speedometer cable
If the speedometer works, but the odometer is not working, there could be a fuse blown if the odometer is digital. If the odometer is not digital, then a gear is broken in the speedometer cable. It should be replaced.
The cable that controls the speedometer needs to be replaced more than likely. That is what had to be done to a Dodge Stealth's speedometer to work properly. ==New Answer == Actually - there is no speedometer/odometer cable on a 1993 Honda. The system is all-electrical. So it has to be either a bad wiring harness/plug connector, OR a bad speedometer head (unlikely).
Have the speed sensor replaced.
The timing or crankcase sensor needs to be checked and most likely replaced.
Our odometer/tripmeter also just stopped working at 220,000 miles. This is an integral part of the speedometer assembly, and cannot be repaired. The entire speedometer must be replaced.
Have your votlage output on your alternator checked? Have your votlage output on your alternator checked?
First check the speedometer cable going into the top of the transmission. If it is not broken the instrument cluster must be replaced.
its is you tachnometer that needs to be reseated or replaced.
You need to have it checked for codes to know what to diagnose.
Your speedometer may have failed, or the speedometer cable that connects to the transmission, or the plastic gear in the transmission may be broken.
