problem: Truck check engine light came on, idle stuck at 1300 rpm. light intermittently goes off and idle returns to 700-800 rpm. bought a scan tool and retrieved the following codes 22 manifold absolute pressure (MAP) or BARO sensor out of range, 32 EGR pressure feedback fault, 95 Fuel pump secondary circuit fault. My question is how to resolve? do I need to start throwing parts or could one issue be causing multiple codes?

 

The Baro sensor fault would be the most likely culprit as it is measuring manifold vacuum.
The correct definition for Code 32 for your vehicle is "EVP voltage below closed limit", that suggests the EGR valve position sensor is a bit out of spec or has a fault, this won't cause your idle issue though so you can put that aside for now. There is no EGR pressure sensor on your truck.
Code 95 can be ignored completely, this is a nuisance code that often occurs on trucks with dual tanks from simply switching between tanks, it has no effect on engine operation.

 

Thank you for the response I really appreciate it and will give it a try.
