2004 Mitsubishi Diamante OBD Code 24, 25, 62 Diagnosis: Vehicle Speed Sensor, Barometric Pressure, and Transaxle Control Issues
I own a 2004 Mitsubishi Diamante LS 3.5L model with ongoing OBD-II fault codes: 24 (Vehicle Speed Sensor - VSS) fault, 25 (Barometric Pressure Sensor - BARO) fault, and 62 (Transaxle Control Module Torque Reduction Signal Fault, including Traction Control Vacuum Valve Solenoid failure). The Check Engine Light is currently illuminated. Given that the VSS code may directly impact transaxle control functions, I'm seeking guidance on how to prioritize troubleshooting steps for these interconnected issues.
Begin with diagnosing the Vehicle Speed Sensor (VSS) fault. Since this sensor feeds critical data to the transaxle control module, a malfunction here can directly trigger or exacerbate OBD code 62 and related traction control issues.
