P2C41Fan 3 Performance/Stuck Off
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2C41 judges the outcome rather than the wiring: fan 3 is commanded on and its circuit checks out (otherwise P0482, P0695 or P0696 would appear), yet the controller sees little or no response, usually through speed feedback from a fan module or a missing current draw. No manufacturer publicly documents this code. Audi's 2022–2023 e-tron GT shows what tends to be behind such faults: road debris entering through the wheel housing liner jammed the radiator fans, logged there under P2B30/P2B32. Porsche renewed corroded engine-compartment blowers in pairs on the 2017 911 after a fan failure warning. CARB asks for outputs to be checked for functional response where feasible. Rising temperatures under load follow. Speed deviations are P2CBB/P2CBC.
- What you may notice
- Engine temperature climbs in traffic or under heavy load
- Weak air conditioning at standstill
- Warning lamp or fan failure message
- Likely causes
- LikelyFan blades blocked by dirt, stones or leaves
- PossibleWorn or seized fan motor, corrosion from moisture
- PossibleFan control module does not drive the motor
- RareWeak power or ground supply to the fan
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
