Hello Everyone,

I have a problem with my 1.9 16v 2005 croma. when a start the aircon the engine is being very sensitive to it. I push the throttle but the car reacts very slowly. when I'm in the traffic it blows but it is hot air especially when the outside temp is over 30 degree celcius. the first moment I start aircon I get P0482. the next day the alarm disappear. if I start the aircon again it appears again at the first moment. does anybody have any idea about this? should I check for gas or sth? in my country it's more that necessary during summer, the temps go up to 43 degree celcius.

Thanks

Hi,
That code rfers to the cooling fan. Most likely a cooling fan relay or fuse.

P0482 Fan 3 Control Circuit

What does this mean? OBD Code P0482 refers to
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 pressure sensor - The vehicle speed sensor (VSS) 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. - The vehicle speed is less than 38 MPH. The cooling fan relay will be commanded ON regardless of vehicle speed when the following conditions are met: - The engine coolant temperature is 151°C (304°F) or more. - The A/C refrigerant pressure is high. The cooling fan may be commanded ON when the engine is not running under a fan run-on conditions described in the electric cooling fan general description portion of the service manual.
Symptoms Possible symptoms of OBD code P0482 - Engine Light ON (or Service Engine Soon Warning Light) - Engine overheating
Causes Possible causes of OBD code P0482
- Fan control relay harness - Fan control relay connector - Fan control relay - Cooling Fan 3 The Error code is generally activated on detection of the following conditions: The P0483 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.
Possible Solutions - Replace the malfunctioning fan control relay 3 "

The fan is commanded on when the aircon compressor clutch is engaged.
Could also be a bad earth.

Hello Robert,

thank you very much for this great answer. It was very useful. I just need to clear something.is the item in the photo you are referring to or is it another one?

Hi Robert,

No need to rush. I sent you the picture because I saw somewhere in some other posts that they were referring to this item. This is placed between two front fans and it's the fan regulator or sth. like this. Anyway when you find sometime please take a look l. I appreciate it.

Thanks.
