Intermittant High Idle (again)

[tom4bren]

Can you take a pic of what you unplugged? That seems to be the question of the day.

Ok... so I just followed the PS test procedure and my A/C did not cut out when I turned the steering all the way to the left; and with A/C off, turning steering all the way left did not increase the idle.

Looks like the PS switch is a good suspect but I just spent 20 min underneath the VX and couldn't see any wires coming out of the PS module... where the hell is it? no one has pics on this forum... seriously?

Can't take pic right now but.........right above PS pump there's a large group of wires and gray connection. About 2in below that is a single wire offshoot, follow that to a small grey connector, unplug it. Did mine, RPM's went from 1400 to 800ish

Thank you for the description of where about it is, I will look again. Been on the internet this morning and that PW switch must be made out of gold because it's about $178 from both isuzuparts and O'Reily... Holy Cow !!!

I unplugged mine without replacing it, read that on planetisuzu I think. Haven't noticed a difference with steering

When I had my engine replace a couple of years ago, the shop found that the wire going to the pressure switch on the steering pump was broken/cut and probably had been for a while given the oxidation on the exposed wires. Maybe it was broken from the day I bought it because I never noticed a problem. They order a new switch (and it was expensive) and installed it along with the new engine, but the VX didn't seem to drive any differently.

I finally found the grey PS switch connector and unplugged it - however, as I lightly pulled up on wire just to see where the h$% this mysterious switch is on the pump, it was not even connected to sensor - looks like it was broken off probably when I had my engine replaced. Anyhow, I was hoping the high idle issue is the switch but I guess not if it was never connected

Subscribed, mine is doing this intermittent high idle too. So aggravating. Haven't replaced anything yet, but I will be looking into this power steering pressure switch

Had similar problem. Ended up being the Idle control valve

There is a wire coming from the power steering pump. Unplug it.
