2002 Tahoe speedometer quit working and trans will not shift, ABS light on.
NEW ANSWER: You need to have the engine and transmission scanned with an OBDII engine scanner so you can find out what speed sensor has gone bad / quite working.
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.
the speedometer on my 97 toyota camary stopped working and the check engine light came on why
speed regulator sensor needs replacement
Check the speed sensor.
wipers,headlights,speedometer,door locks,air conditioner,electric mirrors, stopped working
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.
If the speedometer and abs light are not working then you have a speed sensor problem. If the speedometer or odometer are not working then you will need to take it to the dealership and have them send it off for repair.
Something in the speedo circuit has possibly failed and the computer set a code for it.. Have it checked for codes.
Possible abs sensor failure.
I once had the same problem in my 89 Sunbird turbo. The computer "ECM" went bad and the speedo stopped working. I would see what ECM codes you have causing the check engine light and go from there.
If the ABS light is flashing it means the system is malfunctioning but still working. The dash light behind the speedometer is burnt out.
replace the headlight. your indicator lamp inside the vehicle has nothing to do with your headlight working.
