My Car Hyundai Elantra GLS 2001 check enigne light is on.. and I received code P0107, P0715, P1500...What is the real problem? Can it be Fixed, if Yes, What the total cost will occur to fix these problem?

Any problem can be fixed with a little diagnosis. Well the P0107 is a MAP sensor code( Manifold Absolute Pressure Sensor) this is usually caused by a bad sensor or a bad connection, a vacuum leak could also cause this code to appear. The P0175 is a input shaft turbine speed sensor which is in the tranny, the P1500 is a vehicle speed sensor which is also in the trans. I would start and look for a possible bad ground or a bad connection on the trans. Does your speedo work? If you cannot find any bad grounds or bad connections, have the codes cleared and drive the car and see which codes come back. You would be surprised what kind of problems a bad ground can do...... Hope this helps you out......
