When do I get a p0481 code on my engine?
When do I get a p0481 code on my engine?
The P0481 code is detected when the Engine Control Module (ECM) detects that the commanded state of the driver and the actual state of the control circuit do not match. Engine Light ON (or Service Engine Soon Warning Light) The ECM controls the cooling fan by grounding the cooling fan control circuit which turns ON the cooling fan relay.
What is the p0481 code for cooling fan 2?
P0481 code definition. The P0481 code identifies a problem with the control circuit for cooling fan 2. It is often associated with the P0480 code.
What does it mean when your ECM says p0481?
Often when the P0481 code is observed, it is immediately assumed that either the cooling fan itself needs to be replaced or the cooling fan relay is faulty. There are a number of sensors the ECM (engine control module) uses to control the cooling fan relay. These include:
What does the OBD code p0480 mean?
To prevent overheating when there’s minimal airflow through the radiator, the engine is equipped with a cooling fan, which is electric on modern vehicles. The OBD-II code P0480 registers when the vehicle’s powertrain control module (PCM) detects a potential problem with the engine’s electric cooling fan or its control circuit.
What does the OBD code p0481 mean?
It is often associated with the P0480 code. What the P0481 code means. P0481 is the OBD-II generic code for a problem with the control circuit for cooling fan 2. The cooling fan should be commanded on under certain conditions where the engine requires more cooling, and this is controlled via the cooling fan relay.

What does the p0480 code mean on an Audi?
The P0480 code is detected when the Engine Control Module (ECM) detects that the commanded state of the driver and the actual state of the control circuit do not match. The ECM controls the cooling fan by grounding the cooling fan control circuit which turns ON the cooling fan relay.
