38810, I have a CEL P0551!!!!
Posted by Lateralus, Dec-04-02 06:46 AM
i went to autozone (free diagnosis) and this came up, so i checked my power steering fluid and it was low, so i added, then when i was on the freeway, it came up again, i checked my fluid level, and it was fine, so i got another diagnosis, and it was the same code as before? so what could it be? a bad sensor? and if it is, how easy is it to check it and/or replace it? thanks. BTW I have 99 eclipse gs.

It's not going to hurt anything. All that switch does is monitor changes in pressure within the pump, so that when the ecu detects a pressure spike (increased load on the pump from turning) it can adjust the idle air motor so that you don't have an RPM dip.
Make sure it's plugged in. It's a one-wire push on style connector on the front of the pump. Yours may be different.
