Mil on, DTC P1195 ( boost/map sensor circuit malfunction ) found in     
memory.                                                                 
                                                                        
1.Monitor boost / map sensor voltage readings using the NGS tester and  
  confirm reading are within specifications. also monitor the sensor    
  after a hot start to confirm that sensor reading change when EGR boost
  sensor solenoid swithes OFF to ON to OFF, when the system is          
  functioning normaly the the test will only occur once, but if there   
  is no change in reading due to no opening, closing or blockage of     
  the solenoid ports, EGR valve port,or within the connecting hoses     
  the PCM will repeat this test three times. But this does not mean     
  solenoid doesn't stick occasionally.                                  
2.Inspect boost sensor hoses for water.                                 
3.Inspect boost sensor solenoid for leakage, blockage and/or sticking   
  caused by rust build-up.                                              
4 Inspect EGR valve "hose" port for blockage.                           
5.Replace boost sensor if sensor was produced before November 96.       
Sensor can be identified by stamped (not molded) in 4 digit code on     
the top of the sensor.                                                  
                                                                        
Example: 6Y26  6 = 96, 3 = March,     26 = data                         
               7 = 97  X = October                                      
                       Y = November                                     
                       Z = December
