Saturn dealer is looking at vehicle. they tell me that the throttle plate in the throttle body is getting moisture in the hose and moisture is freezing, which won't allow car to drive.
The Saturn manual says that ''reduced power'' is related to the oil pressure.
Who is right? Am i paying for something unnecessary? Is the mechanic diagnosing wrong? he didn't even know that light is related to oil pressure and i told him where to look in the owners manual
Reduced power messge is not caused by oil pressure. i assume this a 3.0L v6. this engine has a electronic throttle body which is a electric motor that operates the throttle plate that takes the place of a throttle cable. in cold weather the pcv (positive crankcase venelation) system accumulates moisture that will form on the throttle plate, in cold weather the water freezes and causes throttle plate to stick. when the ecm detects any malfunction whithin the throttle control circuit it is put in to reduced power mode that limits throttle position. usually resets after ign. is cycled. there is a service bullitin to re-position pcv hose behind throttle plate to reduce moisture bulid-up on throttle plate. your saturn dealer can perform this service.
This dosn\t explain the reduced power light that comes on in the summer witch mine does

thanks for the help. This is similar to what Saturn explained. I had to get it fixed either way, because I couldn't drive the car. Added to delay was Saturn didn't have the part and my car was in the shop because they had to order it.....then the volcano here in Alaska kept blowing, so all flights cancelled - no parts flown in for a week! Oh well.
Thanks again for your help.
Same exact things for me. The shop just called and said it was the throttle and that the part itself is $600! Does that sound too much to anyone else?...
