What does p0480 mean on a cooling fan?
All our repairs are backed by our 12-month / 12,000-mile warranty. P0480 is a general OBD2 trouble code that refers to the a malfunction within the cooling fan control circuit. This code is similar to P0481 and P0482 codes. P0480 means that the cooling fan 1 control circuit has a malfunction.
What causes the p0480 OBD-II trouble code?
What causes the P0480 code? 1 Faulty cooling fan 1 2 Poor electrical connection in the fan circuit 3 Failed fan control relay has failed 4 Failed coolant temperature sensor 5 Faulty AC pressure switch 6 VSS not operating properly
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
What is the diagnostic code for cooling fan 1?
P0480 is a diagnostic trouble code (DTC) for “Cooling Fan 1 Control Circuit Malfunction”.
How does the p0480 cooling fan relay work?
The PCM (powertrain control module) senses the increase in engine temperature through the CTS (coolant temperature sensor) located near the thermostat. When the temperature reaches about 223-degrees F (value depends on make/model/engine), the PCM will command the cooling fan relay to turn on the fan.
What does DTC code p0480 stand for?
Code P0480 is set when your PCM detects a potential problem with the engine’s electric cooling fan or its control circuit. What Does the P0480 Code Mean? Diagnostic Trouble Code (DTC) P0480 stands for “Fan 1 Control Circuit.”
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
What causes a faulty fan control relay 1?
Potential Causes. The causes for this DTC may include: Faulty fan control relay 1. Fan control relay harness is open or shorted. Circuit electrical connections poor. Faulty cooling fan 1. Faulty coolant temperature sensor. Fan cooling fan harness is open or shorted.
What causes an error code on a fan relay?
There are multiple factors that can lead to this error code. Some of the most common possible causes are: Defective faulty fan control relay 1. Faulty cooling fan 1. Open or shorted fan control relay harness. Open or shorted fan cooling fan harness. Poor electrical connections in the cooling fan circuit. Defective coolant temperature sensor.
What is the OBD2 code for a cooling fan?
P0480 is a general OBD2 trouble code that refers to the a malfunction within the cooling fan control circuit. This code is similar to P0481 and P0482 codes.

When do I get a p0480 code on my ECM?
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. P0480 DODGE Possible Symptoms Engine Light ON (or Service Engine Soon Warning Light) Engine overheating P0480 Dodge Description
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 causes the p0481 control circuit malfunction code?
What causes the P0481 code? The cooling fan 2 control circuit malfunction code may have several causes: There is damage or a short in the harness connecting the cooling fan relay causing a poor connection. The wiring connecting the cooling fan to the harness has a short or other damage causing a poor connection.
What’s the difference between p0481 and p0472?
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. Check engine light (malfunction indicator lamp) illumination and code P0481 set
What causes the cooling fan 2 control circuit malfunction code?
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. If this does not take place, the Check Engine light will illuminate on the dashboard. What causes the P0481 code? The cooling fan 2 control circuit malfunction code may have several causes:
When is the p0480 control circuit code detected?
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. The PCM controls the cooling fan by grounding the cooling fan control circuit which turns ON the cooling fan relay.
When does the pcmcontrol turn on the cooling fan?
The PCMcontrols the cooling fan by grounding the cooling fan control circuit which turns ON the cooling fan relay. The cooling fan relay will be commanded ON when the following conditions are met: – The engine coolant temperature reaches 106°C (223°F) or more. – The A/C clutch requested. – The vehicle speed is less than 38 MPH.
P0480 is a diagnostic trouble code (DTC) for “Cooling Fan 1 Control Circuit Malfunction”.
