What does it mean that the check engine light goes on for a few days and then off again, repeated a few times within a month? Is it dangerous to continue driving with this problem until it can be repaired? What should this repair cost (minus the part, which I know is relatively inexpensive)?

Thanks!

P0551 Power steering switch performance

What this is for is to idle the engine up as a load such as the power steering is placed on the engine , this helps maintain a target idle. Is it dangerous there was never a accident because of this. The purpose of the CK ENG LT program is to protect the catalytic and the catalytic is to protect the enviroment from harmful emission produced by vehicles, So if the repair has to wait, you are a contributor to harmful emission into the atmoshpere. The repair not expensive, it just the power steering switch, depending on the availabilty they may sell the power steering hose with it. and the power steering fluid.
