A/C Refrigerant Charge Loss
Key terms: SAE J2012: the standard generic code list · Powertrain: engine, transmission and emissions
1What it means in plain English
This range covers vehicle speed, idle and oil-pressure control, charging-system voltage, and brake-switch circuits.
2Common causes
- Carbon build-up in the throttle body
- Faulty idle air control valve
- Faulty vehicle speed sensor
- Faulty charging system or weak battery
- Wiring or connector fault
3Can I drive?
Codes in this range include oil-pressure, brake-switch and charging-system voltage faults. If the oil-pressure warning light is on, stop the engine as soon as it is safe and do not drive until it is diagnosed. If the battery or charging warning light is on, drive straight to a workshop: the car can stall when the battery runs flat. For any other P05 code, have the car diagnosed promptly rather than continuing to drive.
