Having problems with your 2004 Chevrolet TrailBlazer ?
MAP sensor code shows fault , replaced sensor, code still goes on and off, book says to check all vacum lines for cracks or leaks.

After you replaced the sensor, you will have to have a scanner connected to the computer again and have the trouble codes cleared. Otherwise the original code is still causing the light to come on.
