Chysler uses a proximity switch to count the revolutions on the drive axle, which gives you the speedometer input. When the computer loses the input it stores an error code, I believe it's 15, in the computer. The connection is just a simple plug and it's exposed to a lot of heat, cold, and moisture, being way down there on the bottom of the car like that. So after a while it's bound to get a little loose. Maybe it's even got some crud on the contacts. SO if you're inclined to do a little crawling around. Jack the car up. USE JACK STANDS, Of course! and crawl under the passenger side front. Look at where the drive shaft for the passenger wheel comes out of the transmission. There's a neat little doohickie there with a plug coming out of the top. That's your speedometer pickup. Look for broken wires, obviously. If you don't see anything like that, I would recomend getting a can of electrical contact cleaner, and give a liberal hosing to the male and female plugs. It will probably solve the problem.
Nope, bet it was the other way around... Your speedometer stopped working and your check engine light came on. A broken speedometer (don't know what car so I can't pinpoint it) will cause a whole bunch of codes.
You may need to replace the speedometer fuse. The speedometer cable can cause your speedometer to stop working. The speed sensor can also cause the speedometer to stop working.
There are a few reasons that could cause the speedometer to stop working on your Toyota Camry. If the mileage is still working then the speedometer cable end is damaged. If both the odometer and speedometer do not work then the cable is most likely broken.
Either that, or the speedometer cable went bad.
There are several things that can cause your speedometer to stop working. The most common cause is a blown fuse. The second most common cause is a malfunctioning speedometer cable.
Broken speedometer cable?
There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired
there is a sensor in one of the drive shaft that finds the speed it could either be that or the engine computer is failing
The gears in the speedometer are stripped. If the odometer is working then you have input.
TCM Malfunction, And/Or Speedometer Sensor Malfunction.
