P0482Fan 3 Control Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- The engine module switches cooling fan stages through relays, pulling each relay coil to ground. P0482 concerns the control circuit of the third stage or relay: with the driver off the line should sit at battery voltage through the coil, and the internal pull-up level means an open circuit (Saab ME9: more than 1 s, 10–18 V, engine running). On the GM-based Saab 9-5 of 2011 it is relay 3 (medium stage) of a two-fan network, with shorts reported as P0695/P0696. GM tables list P0482 only in fault groups; Ford's OBD summaries do not contain it. One fan stage then fails.
- What you may notice
- Check engine light on
- One fan stage fails – temperature rises in traffic or when towing
- Air conditioning weaker at standstill
- Likely causes
- LikelyFan relay 3 faulty (coil open) or not seated properly
- LikelyControl wire open or high-resistance, corroded or backed-out pins
- PossibleRelay coil supply missing (fuse, supply wire)
- RareDriver in the engine module
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
