The "S" warning light is blinking on my 91 accord. Is it more than likely just the speed sensor? Will it do further damage if it isn't fixed soon? Everything else seems to be fine and it shifts great. What is the expected price of the sensor and how hard is it to fix? Thanks!

 

IS the "s" light on your dash, that can be controlled by the button on your shifter.

 

o by the way, does your car have rouble starting, i mean does your car not start

 

$40 bucks on ebay . to install all you need is an a 10mm. now is the cluster telling you how fast you going ? if it is it might not be your speed sensor

 

The "s" light on your dash is to your tranny, when the "S" is off that means your tranny is in regular mode, if your ''s'' light is on that means your tranny is in sports mode. but my problem was that my main relay was bad so i needed to get a new one. i don't know what your problem is.
