Check engine light code 48
I took my car to a mechanic to check why the CEL was coming on and code 48 came up, LAF (linear air flow sensor)problem. Has anyone experienced this? I'm getting on average, 28mpg. I'm getting horrible gas mileage for this car. What should be fixed or changed out?:confused:

48 is lean air fuel sensor

the scanner has the wrong description.
VX and HX are the only ones with a lean-burn/wideband o2 sensors. i'm 99% sure that's your problem especially given the horrible mileage search on honda-tech.com |
It is a linear air flow sensor - it is commonly mistaken as lean. It's called linear because the voltage/lambda relationship is nearly linear - unlike a narrow band sensor which most definitely isn't.
If the CEL stays on all the time and reads code 48, then it's likely the sensor. If not, the sensor may be fine and you have another problem - misfiring cylinder being the most likely source although there are other possibilities. |
Either way it's referring to the O2 sensor.
