How do I fix code P0480?
What repairs can fix the P0480 code?
- Replacing the VSS sensor.
- Replacing the engine coolant temp sensor.
- Repairing or replacing of the fan wiring harness.
- Replacing cooling fan 1.
- Repairing electrical connection issues.
- Replacing AC pressure switch.
- Replacing the fan control relay.
What is a cooling fan control circuit?
Diagnostic Trouble Code (DTC) P0480 stands for “Fan 1 Control Circuit.” The engine cooling system uses liquid coolant that absorbs heat from the engine. The coolant then goes through the radiator that’s located at the front of the vehicle.
What is a fan 2 control circuit?
P0481 DODGE Cooling Fan 2 Control Circuit – The Powertrain Control Module (PCM) controls the cooling fan 2 (high speed) relay by grounding the (N112) high rad fan relay control circuit when it is determined that high speed fan operation is required.
What is code P0481?
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 tells the cooling fan to come on?
The engine temperature should trigger the fan to turn on. It will also turn the fan off once the engine has cooled to under 200 degrees. You may have heard of a part called the radiator fan switch or temperature fan switch. This is linked to a thermostat and works much like your home’s HVAC system.
Should radiator fan run all time?
An electric fan SHOULD NOT run all the time. The fan turning on is normal and a consequence of the hot coolant, not a cause. The coolant may not be moving due to a water pump problem, blockage in the radiator or hoses, or a stuck valve, i.e., the “thermostat” in the coolant line.
Why does my radiator fan not turn off?
If the fan doesn’t stop running, plug that sensor back in and unplug the coolant temp sensor on the thermostat housing. If the fan stops running, replace that sensor. If the fan still runs after unplugging both sensors, then problem might be with radiator fan control module located behind the glove box.
What causes cooling fans not to come on?
Six things may prevent an electric cooling fan from coming on: Defective temperature switch, coolant sensor or other sensor. Engine thermostat is stuck OPEN (engine never gets hot enough to turn on the fan) Faulty fan relay.
How can you tell if your thermostat is stuck?
If you see your temperature gauge going into the red within the first 15 minutes of driving, your thermostat may be bad. Generally, if your vehicle is overheating within 15 minutes or so of driving it, this may be a sign that the thermostat is stuck. Step 2: Check the radiator hoses.
Should I use a 160 degree thermostat?
Keep in mind a 160 thermostat does not guarantee your engine will run at that temp. All it is going to do is let the water flow earlier. Cold AIR, will increase power… but cold ENGINE will decrease it. You actually increase power, by upping the heat of an engine, as long as you can do so without causing detonation.
Will a lower thermostat help overheating?
A low-temp thermostat gives the cooling system a head start. This will help to prevent Engine Detonation and overheating.
What is the best engine temperature?
around 212 degrees Fahrenheit
