P3245

What does P3245 mean?

P-code P3245 means "Inverter High Voltage Out of Range (Low)". It is a manufacturer-specific diagnostic trouble code (DTC) in the electric motor / drive system. The inverter high voltage out of range (low) is operating outside its expected performance range, suggesting a mechanical or electrical issue. This is a critical fault — stop driving immediately and seek service. This code applies to OBD-II compliant electric and hybrid vehicles.

Possible Causes

• Sensor output is electrically valid but mechanically out of expected range
• Mechanical wear or damage in the monitored component
• Contamination (fluid, dirt, or debris) affecting sensor accuracy
• Intermittent electrical connection causing fluctuating readings

Recommended Actions

1. 1 Stop driving safely as soon as possible — this is a critical fault that may affect vehicle operation
2. 2 Scan for all DTCs with an OBD-II scanner — note any related codes stored alongside P3245
3. 3 Inspect the electric motor / drive system component and its wiring for visible damage
4. 4 Check for water intrusion in connector areas and clean contacts if corroded
5. 5 Clear the DTC, road-test the vehicle, and re-scan to confirm whether the fault returns
6. 6 If the fault returns, have the vehicle inspected at an authorized service center immediately
