po481 help, 1998 camaro ss

[mikeyblue01]

Hi guys. just looking for a little help with an issue im having

Car...1998 camaro ss, 5.7 ls1, all stock

Problem... Engine code po481, chilton manual reads as cooling fan relay 2 and 3 control circuit

What I have done.... tried to reset code, came back on instantly, replaced all cooling fan relays, checked all fuses, hard wired both fans to test fan motors, turned on ac and the left fan turned on as it should (left, if you were looking at the engine from the front of the car), I have yet to see the right fan turn on during operation, car does not overheat, at full temp the needle bearly gets past the quarter mark

any input would be appriciated, thx, mike b

I have a 2000 camaro ss that I just purchased and mine is throwing the same code (P0481). I haven't really gone through a lot of troubleshooting but I believe both fans are working so I don't understand the code?
