Check engine code 13?

"Indicates a problem with the manifold absolute pressure sensor vacuum source"
Can someone translate this to something I can understand, and how to solve this problem?

Thanks!

not sure of the location but the MAP sensor is on the intake manifold, there should be a couple of wires coming out of it and apparently a vacuum line. check the connection and that the vacuum line doesn't have any leaks, or it could be bad sensor.

#13: Slow change in MAP from start to run. Basicly, the PCM didnt see a significant change in the sensor reading from when the truck was starting to when it was at idle. Its on the firewall just to the drivers side of engine, has a vacuum line and an electrical connector. Check vac line for blockage or being pinched or disconnected. Most likely is a failed sensor. If your able to, check for 5volts on pin 3 (violet with white stripe) and ground on pin 1.
