What does the p0480 code on my car mean?
What the P0480 code means. P0480 means that the cooling fan 1 control circuit has a malfunction. The vehicles ECU has tried to control the cooling fan 1 and it has failed to operate or a fault was detected. The ECU then triggers a Check Engine Light to illuminate on the dashboard.
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.
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 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.
What the P0480 code means. P0480 means that the cooling fan 1 control circuit has a malfunction. The vehicles ECU has tried to control the cooling fan 1 and it has failed to operate or a fault was detected. The ECU then triggers a Check Engine Light to illuminate on the dashboard.
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
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.
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 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 the service engine soon warning light mean?
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. 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.
What happens when purge solenoid is not activated?
When the purge solenoid isn’t activated, the ECM should see a high voltage on the ground circuit. When the solenoid is activated, the ECM should see the ground voltage pulled low, close to zero.
Where is the relay control circuit on a DTC p0480?
Disconnect the ECM connector containing the relay control circuit. Turn the ignition switch to ON. Search for the relay control circuit at terminal 5 in the ECM harness connector with a fused jumper wire connected to ground. Check the connections at the relay.
What is the diagnostic code for cooling fan 1?
P0480 is a diagnostic trouble code (DTC) for “Cooling Fan 1 Control Circuit Malfunction”.
