2009 Ram 1500 P0750 Transmission Code: Related to P0456 EVAP Fault?
The check engine light was on, and when I used my OBD2 scanner, the only initial code displayed was P0456 (Evaporative Emission System Leak). After resetting the system, a new code appeared: P0750 (Transmission Solenoid Circuit Malfunction). I'm wondering if these two codes are related or if they are independent issues that occurred simultaneously in the ECM.
Refer to this forum's troubleshooting guide for detailed causes and solutions of OBD2 trouble codes. There is no direct cause-and-effect relationship between the P0750 transmission solenoid code and the P0456 evaporative system leak code; they are likely stored in the ECM at the same time but represent separate systems with different underlying issues.
