What does code p0480 mean on Jeep radiator fan?
Include a few extra bits of circuitry (more relays) that help trigger the fan on when the AC is running, or the engine temp crosses a certain level. In addition to throwing a P0480, these fans can also throw a code in the P069X range.
Why is my Jeep radiator not turning on?
The fan will turn on after the temperature reaches about half. Usually comes on when the car is standing still due to the small amount of air circulating through the radiator. Too many mods to list… No the AC will turn the radiator fan on to pull air across the condensor.
How to diagnose a Jeep JK radiator fan issue?
The Relay in the TIPM (K11) labeled “Radiator Fan Low” The dual relays over by the brake master cylinder labeled “Fan Relays” on the internet (Mopar Part 56055666AB) The lack of a P069X style code being thrown led me to believe this was a unique problem with only the “high” speed part of running the fan.
What to do if your Jeep Grand Cherokee cooling fan is not working?
If the fan does not operate, continue troubleshooting. Switch the wires to the opposite terminals. If the fan still does not operate, the cooling fan motor and assembly must be replaced. If the fan does operate, the vehicle must be taken into a professional service center for testing on the PCM, which controls the cooling fan relays.
Why is the radiator fan on my Jeep not working?
So I left the car wash this morning an noticed my temperature gauge was rising higher than it normally does. I pulled into the nearest parking lot and lifted the hood. I noticed that the engine seemed really hot (temperature gauge got to about 3/4). Then I realized the radiator fan was not even going.
When to use the p0481 Jeep error code?
– Fan control relay harness – Fan control relay connector – Fan control relay – Cooling Fan 1 The Error code is generally activated on detection of the following conditions: The P0481 Jeep code is detected when the PCM detects that the commanded state of the driver and the actual state of the control circuit do not match.
What is the OBD2 code for a jeep cooling fan?
OBD2 Code P0480 Jeep definition: The electric cooling fan is controlled by the powertrain control module (PCM) through the cooling fan relay based on inputs from the following components: – The engine coolant temperature (ECT) sensor – The intake air temperature (IAT) sensor – The A/C selector switch – The A/C refrigerant…
How to troubleshoot a jeep PWM fan relay test?
Radiator Fan Motor Circuit Wiring Diagram (1999-2003 4.0L Jeep Grand Cherokee). TIP 1: The way I’ve designed the Jeep PWM fan relay test, you’ll need a scan tool that can read live data (not a code reader), since you’ll need to keep an eye on the engine’s coolant temperature with it.
