Swapped a assisted steering Rack n pinion with one that has no sensor is this bad?
Hey guys. So what’s done is done. My 07 450 has sensor on rack. Mechanic ordered same as I heard him on phone. But it turns out they sent one without assisted steering and no one caught it until I went to get the car and asked did they plug it in. Then found this out. So what negative consequences should I expect how bad is this situation?So far it’s driving normal. I really appreciate if someone can give me a realistic answer. At this point complaining or doing things by the book like removing and replacing again is not really a option. It was a big job. Now if it’s going to cause dangerous issues then he’s willing to do it again. It’s a friend of mine. We agreed I’ll drive it and see if anything goes wrong.
Thanks for any help

Isn't that "sensor" for the speed sensitive power steering?
The effect would be either there is too much assist at highway speeds or too little at parking speeds. The wheel should be pretty light when parking and rather heavy on the highway.

Yes that sensor. I’ve not been on Highway yet to test but what I’m feeling after you mentioned it is actually tighter steering overall. I only drove it home so I didn’t really notice anything but checking it right now it’s definitely much harder steering. If that’s all that will happen I’m fine with that as I really only drive local and tow my boat with it so harder steering for towing is not a bad thing.

Yes, some 164s did not have the variable speed steering that lightens it up at low speed.
You now have one of those.
You should be fine unless the steering is overly sensitive at high speed, which it doesn’t sound like it is. I would be prepared for possible ESP or BAS code and/or stored and current faults related to “implausible value” from the variable speed sensor.

Incase anyone reads this. YES you can use a non steeeing assist rack on a car equipped with the sensor from factory. I’ve been driving all these months after mechanic made that mistake installing wrong rack.
BUT the negatives other then what i mentioned months ago is you will get the ESP light on and esp button will not work.No limp mode or anything making you feel esp is causing issues. I can live with this.And it only comes on if you go on highway.It will reset itself and go away after a week of city driving and never come back on until hw driving. You can do 50-60mph in city and it won’t come on.Very odd.
But on Highway it will come on at even 25-35mph soon as you get on the ramp it comes on as if it knows it’s going on the highway.That’s crazy odd. I’ve tested this many times.10 Seconds after getting on Highway boom esp comes on at 20,30 etc mph. Drive on service road next to highway at 50mph no esp light. Merge onto hw esp light. 🤷🏻
Anways Had I known it would work I would have just purchased the no sensor rack n pion new as it was only $189. The one with sensor was something like 400-500 new wich I wasn’t gonna spend. what I bought used for $200 was correct one with sensor but rookie mechanic didn’t catch the wrong part was sent by part supplier.
