2001 Hyundai Elantra 46,000 miles auto transmission:
This is my commute car and I have been taking good care of it. During the last 6 months I have had to replace O2 censor 3 times and Speed Censor once. How many O2 censors and speed censors are there in the car? Or I am being fooled?

That depends on the engine size. Generally, if the engine is a 4 cylinder, there are 2. 6 cylinder would be 3 to 4, but generally 3. Speed sensors would be 1. Now I might add that when a lesser quality sensor is used, the life is not too long and any kind of jolt can put an O2 in to the garbage can.

Check the manifold for any cracks and make sure the flex pipe on the exaust isnt leaking as these leaks will cause an H02 sensor slow response or performance code, and it is because of the leaky pipe
