Cummins supplies the new sensor for less... Question though do you have any kind of add on module (Edge Juice or simular)? Here is more information on the code... http://forum.mopar1973man.com/showthread.php/2571-P0237-Map-Sensor-Voltage-Too-Low

If you got the ECM plugged into the MAP sensor and the code is coming back without the Edge Comp plugged in then the sensor is bad. But if the code is coming while the Edge Comp is hooked up the the boost fooler is bad in the Edge Comp and would have to be repaired by Edge Products... As for the P1688 and P0251 codes are rarther serious codes and shouldn't be taken lightly. I would keep a close eye on the error codes and the fuel pressure for awhile...
