Ok, I have a 1990 Daytona and I am having some sort of electrical problem. There are days the power door locks stop working, the radio powers on and off and now the odometer and tripometer stopped working.&nbsp\\; Now today after my mechanic worked on the brakes, the turn signals do not work, nor do the 4-ways.&nbsp\\; After cursing a bit, I gave up.&nbsp\\; My husband went back outside and played with it and the 4-ways flashed at him after he got out of the car, he turned his back, they flashed again, turn signals working intermittently.&nbsp\\; It seems he got them to work...for now.&nbsp\\; Any ideas where I need to look to fix the problem?&nbsp\\; I get error codes 12, 15 and 21(which I know is the O2 sensor)the other two are electrical, but I am not too sure what they mean.&nbsp\\; Any help appreciated.&nbsp\\;

Code 12 means that the battery was disconnected before 50 key-ons ago. Normal code that comes up if the battery dies or gets disconnected (they may have done it during the service you had done).

Code 15 is no speed and or distance sensor signal. Best place to describe the location (if you have the electrically controlled transmission [EATX]) is on the backside, near the exhaust bank below the heater core lines (heater core lines are on the left side of the master cylinder looking in from the front).

Code 21 you are correct on

Code 15 could also correlate to the fact that your odometer is not working as well.

Hope this helps!

Yes, you are correct about the code 15. I just replaced my Speed sensor last month and I got the same code with the same symptom. My Speedo, Trip and Odometer all stopped working (all other guages worked) and the code accompanied the symptoms. Replace your speed sensor and you will fix your problem. It will cost about 50 bucks no big deal there. Your electrical problems may or may not be intertwined. It's good to check the wiring. Maybe try a multi-meter and poke and prod around a little and see what you can find.
