2.5 Power Steering Pressure Line Sensor Port Plug

[XCRN]

Does anyone know what thread size or what fitting I need to block off the pressure sensor port on a 2.5 power steering pressure line?

I plugged mine, but can't remember what I used....seems like I had to solder something but it's been awhile back. Good luck with it.

Im hoping to do solder-less and use purchased bolt-on parts since I am doing an LS swap for someone else and I want as many wear components to be off the shelf as possible so they can handle any maintenance them selves.

So is the idea here that you don't want the engine to bother increasing its RPMs when you're at full turn on the steering, and would rather just plug the port? And you'll just put up with the CEL or clear it when it comes up?

And did you ever get this sorted out? Mine needs to be replaced, but I have never had any trouble without it working, so it seems like an unnecessary feature to me.

is that what happens? I just assumed the pump working harder put a "strain" on the engine via the belt, and the engine reacted. Admittedly I don't really know much about the PS system, or how engines determine how they idle under various load conditions.

I think that only the 2.5s have these power-steering pressure sensors, because (like you said) steering at full turn puts more strain on the engine, and so the engine's RPMs need to increase (in theory) to ensure that it doesn't stall.

I read somewhere that on a 2.5, you should notice the RPMs increasing slightly when you're a full turn. If not, then your sensor isn't working. My 2.5 is currently giving me a CEL for the power steering sensor, and when I hit full turn my RPMs drop a bit. But not low enough to stall, so if I'm right about the intended purpose, then it's not something I care about having.

Swap in a new pressure line without the sensor port.

Swap in a new pressure line without the sensor port.

Will this not cause any CEL trouble?

Doubtful.

I'm trouble-shooting mine again, and came back across this thread. Just to confirm, this is from my 97 2.5 FSM:
