2005 Accord LX 3.0 V6...

Power Steering pump said goodbye over Christmas. ...or so I thought.
After two weeks of zero PS at low speed, it suddenly started working again. Oddly enough is seems to have risen from the dead after I changed out the alternator which ate itself, bearings first, over the weekend. I think the alt was grounding inside the case at the very end. Anyway...do these cars have electronic speed sensitive PS and would the failing alternator have caused it to quit? Otherwise it makes no sense that I would suddenly have no PS and then just as suddenly have it again

 

For the accord hydraulic PS system, the PS system has no electronic controls. The hydraulic pressure put out by the pump is controlled by valves in the rack and pump. Newer accords starting in 2012 (I think) have an electric motor for power steering, so they obviously have electronic controls, but not your 05.

A possible explanation for the loss of power steering is the belt wasn't driving the PS pump when the alternator was seizing. If the PS fluid looked frothy (had air bubbles), then your pump could be pulling in air and causing the issue. Did your PS fluid level remain constant, or did you have a leak where you needed to add PS fluid?

The only preventative maintenance I'd consider is replacing the PS fluid and replace the o-rings on the connections to the pump.

 

Had a bad leak. But I filled the reservoir and it was fine for several weeks before the issue developed

 

I looked back at your previous thread. Did you find the source of your leak?

 

Not yet.
