Why check engine light comes on, speedometer and tachometer act erratically upon initial startup, and radio/CD don't work after jumpstarting another car?
What is your question?
About 5 months ago, the check engine light came on on my 2003 Toyota Corolla. Had it checked out by a trusted mechanic, and he replaced one of the oxygen sensors and check engine light went out.
Several days ago, I jump started another car that had a dead battery. I left the jumper cables attached to both vehicles for 5 to 10 minutes to help somewhat recharge the cars dead battery. I removed the jumper cables and turned the Corolla off and let it sit for about 15 minutes. Upon restarting the Corolla, the check engine light was on, the speedometer and tachometer acted erratically, and the radio/CD didn't work.
I checked all of the internal fuses. All were okay
Can you give me some ideas about what has gone wrong and how to fix it.
