I found out the code for the Service Engine Soon light being on is po 410. An emissions problem with the secondary air pump I am told. Percentage-wise does anyone know which part may be causing the problem? I am o.k. doing some things on cars and would like to trouble shoot this myself if possible. Is this code strictly air pump related, or can it have anything to do with the coolant temp. sensor? We have had the car for 4 days now and this is our first Saturn, so I am just becoming familiar with it. Thanks!
We just bought this car two days ago. The car was fine for the first 100 miles. Now the Service Engine Soon light is on. Is this a reminder for service or would this be a warning something with the engine is actually wrong? It runs fine, fluid levels are o.k.and has 71k miles. This is our first Saturn vehicle. If it checks out o.k. is there a way to reset the light?
