I have a 1991 Honda accord ex WITH 240 k. The car runs great but today the speedometer died running 70 MPH then the s light came on and started flashing. A couple of miles later the check engine light came on. I drove another 20 miles and the car ran fine.
The car has a new battery and the connections are clean and tight. I replaced the TCU probably 4 years ago with a re-furbed unit at $300.00.
I have not pulled the codes, not real sure how to do it.
PLEASE COMMENT!
THANKS
