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.”

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’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 DTC for the cooling fan relay?

DIAGNOSTIC TROUBLE CODE (DTC) – P0480 LOW SPEED COOLING FAN RELAY CIRCUIT FAULT (WITH A/C) The cooling fan relay coil receives the Ignition Voltage directly. The relay is regulated by grounding the control circuit via the driver or the internal switch, a process which is entirely controlled by the ECM.

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.

How does the p0480 Dodge engine control module work?

P0480 DODGE Meaning The electric cooling fan is controlled by the Engine Control Module (ECM) through the cooling fan relay based on inputs from the following components: – The engine coolant temperature (ECT) sensor – The intake air temperature (IAT) sensor
