I have a 2002 Hyundai Elantra. The 10 amp sensor fuse right beside the 15 amp inj. fuse in the engine compartment fuse box keeps blowing as soon as I try to start vehicle. I changed it the first time and it ran about 5 mile, now it blows as soon as you crank the engine. Which sensor is bad? Thank you in advance for your time. Sincerely, XXXXX

The 10 amp sensor fuse beside the 15 amp injecter fuse blows as soon as you crank engine. (This is fuse panel under hood) Would like to know which sensor is bad.
Hello, I am Randall. I will do my best to help answer your questionThe problem is that fuse powers up more than one sensor/itemIt is power feed to both o2 sensors, the crank sensor, the cam sensor as well as the computer itself and the idel speeds control motorYou can unplug each of the 02 sensors,. one in exhaust manifold, the other under car in the exhaust pipe, see if fuse still bows, if so,, then the cam sensor then crank sensor and after all this could lean to failing ECM ( computer)
