Hello everyone, I have a 90 Accord with A/T with 207K on the motor. Shortly
after I acquired it, the S light flashes, and when it does, the speedometer
99% of the time will not work. Occasionally it will with the S light
flashing. The transmission will shift through all gears ( all the time ),
Another symtom is that I got very poor gas mileage, like 320 Km on a full
tank. Someone told me hers can get 600Km. Today I retrieve the code. The
check engine light came on but did not flash. The S light flashed: 1 short
and also dimmer ) and 3 longer flashes ( brighter than the first flash ).
Please help to decode.
Also I need help to identify which one is the lockup solenoid and which one
is the shift control solenoid, they look the same. Many thanks and Merry
Christmas to all.

Mine did the same and it was the speed sensor on the tranny.Eventually the
speedometer will stop for good if you don;t change it

nearly identical to the '90), can be found at
