Hey i have a 1998 honda civic LX (bone stock)and i am throwing 2 codes P0108 (map circuit high input) and P1337 (csf sensor no signal) do these codes make bad gas mileage???
cause i get horrible gas mileage.... i get 205 to a full tank for some reason. (driving normal) and i thought i would throw a O2 sensor code since when those go out, you get horrible gas mileage, but i didnt. what could be the cause of this???

and

do you know of any way i can fix these 2 engine codes, so they dont show anymore???

SO MY 3 QUESTIONS ARE

-DO P0108 AND P1337 CAUSE BAD GAS MILEAGE?

-WHY WOULD I GET BAD GAS MILEAGE?

-HOW DO I FIX THESE CODES TO MAKE THEM GO AWAY?

any help is GREATLY appreciative................................

yes they will cause poor mpg.

to make them go away pick a manual and step through the troubleshooting.

ok found out my map senser was broken so that should be the problem with the map sensor............................ now what do i do about the crank sensor no signal problem??????/

probably a wiring issue.
could be a bad sensor but unlikely.

i know this thread is old but do you have to take out the crank itself to ispect the sensor

No, just remover the lower timing belt cover
