Fuel consumption of my elantra is very high. When i checked the injector pulse width with an oscilloscope, it shows values around 4 - 6.5 ms when engine is idle. Since these values are too high, i did a scan of the engine parameters while its is idling. I did a similar scan for a different elantra car as well. When these values were compared, all parameter values had similar values except the Calculate Load Value (CLV), which is 4-6% in my car and around 45-55% for the other car. (this other car does not have any problem). What would cause CLV to drop this much? Could this difference explain the high fuel consumption?
