i got the same problem
it occured when mechanic tried to solve my fans' problem. My fans were not turning on. He did not have enough time so we connected fans to relay then they began turning on whenever i turn the car on. Then I had CEL and D4 light on. Today replaced radiator (cuz it had some cracks on it) not CEL was gone but d4 still blinking. Speedometer is just perfect.
any ideas?
