power steering sensor broke again

Post by MAKO »

Hi all


I have had hard time.

[Edit] about my '00 citroen xm 3.0l late 24v (rp 08599) [EDIT]

a few days ago, I felt a sudden bump in the steering wheel while
turning my wheel quickly in a narrow parking lot, lost all the power
steering assist at the same time.

I jumped out, was surprised to see LHM spouting around in front of the mission case.

the cause was this. steering pressure sensor.

was broken right in two. sudden hydo-system dysfunction was inevitable

It' no more than a month and 200miles since I replaced it because of
minor leak on 120000 miles!
It's a shame.

2 questions I hope here are many people more in the know.

1. I wonder whether I have to find and fix any problem within the
steering feed pipe such as provoking abnormally high pressure before I
just fit a new sensor. actually the failed sensor seems to be
aftermarket one, which the seller referred as OE number ; 401509Z as
opposed to genuine 401509, and said it's not compatible with my late
24v xm. it's only that I shoud have followed his discription ?

2. there is another similar part just next to it, named "HP-PUMP PRESSURE LIMITER" . makes me imagine that it limits the too much pressure in the
steering line. its wire goes upwards.

what do you think ?


thanks a lot for any advice in advance.

While it is doubtful I could offer any useful advice, in order for the knowledgeable members to help you they will need to know what the vehicle is.

It should be me apologising. I just had another look at your post, and found the required info near the start. Now all you need is an XM fan reading the post and knowing what to do. There are several fans on the forum.

Are you a member of Club XM? They may also be able to offer advise.

Have any other components in the steering or hydraulic systems been recently changed?

Hi, xantia_v6.

thank you for question.

I have replaced
1. hydraulic pipe between pressure regulator and suspension/brake system, one month and 100miles before,
2. front height corrector due to minor leak, 7 months and 5000 miles before.

The pressure limiter is a valve that opens if the pressure gets too high, the "wire" that you mention should be an LHM return hose.
I think that your failed pressure switch was probably just badly manufactured. I would try another one (genuine if possible) and see what happens.

BTW, it would probably not be the worst thing if the pressure switch was replaced by a blank plug, as I believe that its only purpose is to increase the idle speed during parking maneuvers to stop the engine stalling.

Hi, Xantia_V6

thank you for your clear explanation about the limiter.

I will try a genuine sensor which is coming tomorrow and had better drive with some blank plug in the boot just in case.
