What does this mean? I have tried to search online for it...Does anyone have any ideas for me? I can't find any info on it really.

Hello, P0xxx is a generic ODBII code. At least for '00obw (closest service manual i have listing that code) that means

 

A/T DTC P0483 - COOLING FAN FUNCTION PROBLEM

 

DTC DETECTING CONDITION: Two consecutive driving cycles with fault

 

TROUBLE SYMPTOM: Occurrence of noise; Overheating

 

Do the cooling fans seem to turn on at all? Do the funs cycle on and off if th A/C is on? Does the temp gauge seem to get any higher than the middle or so?

I have a '98 Forester.

Temp gauge does not go more than in the middle...once it's all heated up it stays in the same spot. Has not overheated since I have owned it. Only other info I got was from Mitchell on Demand at work...basically saying that it could even be caused by parking next to another vehicle while at idle...strange.

It means the ECU turned both fans on and expected the coolant temp to decrease by X degrees after a predetermined time and it did not.

 

Be certain both fans are operational, The radiator is clear for air to pass thru, nothing blocking airflow, could be a clogged radiator. could be low on coolant. But now you get the idea...... ECU tried to cool the engine and couldn't.
