2000 S40. Check Engine Light

Post by torreg79 »

My check engine light has been on for over a year and I finally had it check out at auto zone and it read the following ccodes P0014, P0015,P0128,P0303,P0456, and P0507. So after reading so many of the post on this site I decided to fix this myself. I am far from a mechanic. So I changed the fuel pressure regulator, idle control valve, thermostat, coolant temp sensor, and a upper radiator hose and thanks to all of you today my CEL is off and today I passed my emissions test in IL. So thank you all.... :D

That was alot of codes, glad you were able to correct them all.

Can I ask why you replaced the upper radiator hose, and what code/issue that was related to? The reason I am asking is that I just ordered a new upper hose, the plastic tee on mine has a hairline crack in it that leaks pretty bad. Is there anything else in that area that could be a concern?

Thanks,

Jeremy
