That system has an issue causing your vehicle to display the check engine light. This is less likely if the check engine light wasn't on before this. It's a coincidence and another system in your car started to experience an issue just after you replaced the fuse. Believe it or not, this does happen even though it is also less likely.

Possibility 1 - The problem that caused the computer's error code which is making the check engine light illuminate was not fully fixed. Even if you replaced the sensor, it may not have truly been a faulty sensor that is the issue. It may have been what that sensor is detecting i. Possibility 2 - There is an issue with the connection to the sensor. I know you checked for loose connections, but did you check the wiring from the computer to the sensor itself? Try doing this by using an ohm meter to get a reading on the resistance across just the sensor, then connect the sensor and find the same sensor wires back at the car's computer.

Test the resistance between those two wires back at the car's computer. They should be just about the same resistance.
