What does the p0481 code mean on an engine?
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.
When to set the p0481 fan relay code?
When the PCM attempts to activate the fan and senses the command and the result do not match, the code is set. NOTE: P0481 speaks of the basic circuit, however codes P0480 and P0482 relate to the same problem with the only difference is they relate to the different fan speed relays.
Is there an OBD-II scanner for p0481?
P0481 is diagnosed with an OBD-II scanner. A qualified technician will use a scanner that is capable of scanning the factory sensor readings (more advanced than one from the auto parts store) to read the code.
What is the OBD code for the radiator?
It is a generic code applying to all OBD II (on board diagnostics) vehicles. While you are driving, air in sufficient quantity is passing through the radiator effectively cooling the engine.

What are the symptoms of a p0113 diagnostic trouble code?
Symptoms Of A P0113 Diagnostic Trouble Code. When the intake air temperature (IAT) sensor fails, and starts to report an extremely low temperature (-38 °F), the air/fuel mixture that the PCM is trying to control is gonna’ suffer. The symptoms of a bad intake air temperature (IAT) sensor are: Check engine light (CEL) is on.
What does p0113 mean in GM 3.8L?
More 3.8L V6 GM Tutorials. One of the most important things we need to know is that code P0113 is referring to a malfunction in the temperature value that the intake air temperature sensor (IAT) is reporting to the PCM. Specifically, that the IAT sensor is reporting a high voltage.
What’s the difference between p0480 and P0 482?
NOTE: P0480 speaks of the basic circuit, however codes P0481, and P0482 relate to the same problem with the only difference is they relate to the different fan speed relays. Check engine light (malfunction indicator lamp) illumination and code P0480 set
How much does it cost to diagnose p0404 Pontiac engine code?
The cost of diagnosing the P0404 PONTIAC code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour. When is the P0404 PONTIAC code detected?
What does the code p0481 stand for?
However, specific troubleshooting steps will vary depending on the vehicle. If your vehicle’s check engine light comes on and after pulling the code you find a P0481 displayed, if refers to the engine cooling fan circuit. It is a generic code applying to all OBD II (on board diagnostics) vehicles.

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.
How much does it cost to diagnose a p0455 code?
The cost to diagnose the P0455 code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
How does the p0480 GMC cooling fan control circuit work?
The P0480 code is detected when the Powertrain Control Module (PCM) 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 PCM controls the cooling fan by grounding the cooling fan control circuit which turns ON the cooling fan relay.
