I have a 1994 Geo Metro whose check engine light is on. I read the code by placing the spare fuse in and reading the flashes.I read that there was 1 flash a pause then 5 flashes. Code 15 which is the coolant sensor. I went to Autozone on Friday and bought a new one and replaced it today. I reset the check engine light. Today I was driving the Metro around town and the light came back on again. Once again it still says code 15. Whats going on?
Thanks for the help.
