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.
check your speedometer sensor located back left of engine bay on top of the transmission
Which fan is not working? Engine fan or HVAC fan?
the speedometer on my 97 toyota camary stopped working and the check engine light came on why
No it will not blow your engine or tranny up it has nothing to do with either of them. The thing to look for is if a speed sensor is out.
There are several possibilities why the speedometer is not working. The VSS, vehicle speed sensor may have failed or become unplugged. The speedometer may have failed, or the ECM, engine control module, may have failed or there could also be wiring issues.
I think you need a speed sensor
The check engine light only comes on for something that affects emissions
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.
You need to have it checked for codes to know what to diagnose.
Bad speed sensor.
Does the speedometer work? Sounds like the electrical connector from the transmission to the PCM is either not plugged in correctly or at all.
