Replacing Oil Pressure Sensor
Hello all,
We are experiencing the "service vehicle soon" message and it's driving us mad! - from a bit of research, I've found that the oil pressure sensor on the VZ's can cause this message.
Does anyone have instructions or could give tips on replacing the oil pressure sensor?
Many thanks in advance.
Who wants chowder?
Can't you just reset the message through the dash??
As far as I know, it can't be reset through the dash.

guys guys guys, remember, service vehicle soon IS NOT A SERVICE REMINDER, this is set when a non emissions related fault is detected,
to the op, have you properly diagnosed what is cauing the issue, buying a new pressure sensor is expensive and reckless way of fixing a problem, there are oodles of fault codes that can cause the svs message, id be getting it checked with a scan tool before replacing parts,

dealer or any other mechanical workshop with a compatible scan tool

HI, I've had the "service vehicle soon" error the last couple of days. Had it checked with a scan tool -free of charge!!!! (not at a dealer, I refuse to go there any more). There were three error codes:
1) Oil Pressure out of range.
2) Oil pressure in range. --?????
3) Lost communications with module.
I wasn't there, but my wife assures me these are the error codes the mechanic told her.
The car is booked in to be serviced on Friday so I will post the results when i have them.
My gutt instinct was faulty oil pressure sender but I don't know about the loss of communications error?
Wait and see with crossed fingers I guess.
BTW - Andymanthanks for setting everyone straight about resetting the service notice. Everyone seems to think it is the same as a regular notice, and it just isn't te same!
Incidentally it does clear - for a very short period in my case - if you disconnect the battery for a while.

no worries, its a very silly of showing a fault code, i can imagine alot of people taking there cars to get serviced and an ill informed or workshop without expirance would just change the oil and filter etc

Got it fixed today. It was the oil pressure switch. Cost $132 for the switch plus half an hour labour.
All good again. No more annoying beeping!!
A bogan with style
Had this fault myself over the last couple days, resulting in oil leaking out of it.. Got the switch at trade price, had to buy a special socket to fit it though...
Took 2 mins to swap over.
Pain in the ass.. apparently common fault? dumb spot for it imho.
travy mate, where do i get oil sensor socket and can i get trade some how? what was the damage trade?{price}
this mite sound silly but i have the same problem and its the oil sensor but where the hell is it i just cant seem to find it help any one
Enhanced Custom Tuned
gen 3/4 its near the oil filter near the sump (90% sure)
alloytec its near the oil filter up the top right of the motor (you will need to remove the engine cover to get to it easily tho)
on both youll need a specail socket to get it off
found the sensor for future reference it is at the back of the engine on top of it near the firewall behind the manifold in an ls1 and the service vehicle soon message dissappeared after i changed the sensor for any one who was wondering
had same problem twice. Cannot be reset from inside the car. You have to replace the oil pressure sender switch. Apparently there was a faulty batch brought into the country. Holden had the same batch as after market. Had to put up with the warnuing and alarm for 6 weeks !!!
i all so had the same.. took it to the dealer and said going to cost $320..they said it was the oil pressure switch.. went and brought a scan tool max scan gs500 the other day and when i connect it up and to see the error code.. i see none come up..as in there are no errors with the car.. can anyone help... i havent change the oil pressure switch and it does comes up with svs "service vehicle soon" .. and do you need a special socket to remove it..
yeh you need a tube socket i forgot what size, i did mine couple months ago and just clear the fault code when done.

Repco sell the oil pressure switch socket for $18 I think it is. I had the same problem and fixed it myself by replacing the oil pressure switch.
Oil Pressure Switch - $65 (from Holden)
Oil Pressure Switch Socket - $18 (Repco)
The problem was annoying me for a few months... was so glad to finally get it fixed for only $83. Actually I sold the socket to a friend a couple days later for $10, so the repair only really cost me $73.
As for the price of the oil pressure switch I think I got very lucky. Rang local Holden dealer and this is how the conversation went;
-ME: Hi, I'm after a price for an oil pressure switch for a VZ
-HOLDEN: They cost $279 but we are out of stock
-ME: Wow, really? $279? That seems like a lot!
-HOLDEN: Ok hold on I'll double check the price
(put's me on hold)
-HOLDEN: Ok they're actually $169 but we still don't have any in stock
-ME: That still seems like too much, I was just on the phone with Ultratune and they quoted $120 to replace the switch, including parts and labour, but there is a 2 week wait on the switches
-HOLDEN: That sounds too cheap, they must not be using genuine parts
-ME: Nope, they are definitely using genuine parts... He told me they were waiting on the switches from Holden and is unaware of any aftermarket replacements
-HOLDEN: Ok let me double check again
(puts me on hold again)
-HOLDEN: Well we do actually have them in stock and they are only $65. Sorry for the confusion but that part has been superseded a few times and I had to track it back through the system. I also don't normally work in this department, I'm just filling in for the day
-ME: Excellent, see you in 15 minutes
I haven't heard of anyone else getting the switch for any lower than $65... best alternative I found was about $85 off the net somewhere, can't remember the site.
did the fault go away after you change the switch or did you have to clear the fault with scan tool after you change the switch?

Fault goes away straight away... no need to reset anything. Just replace the switch, it's all you need to do, and it's very very easy.
so does the scan tool pick up that fault.. or is that a different sort of fault.. the scantool a got is maxscan gs500.. and at this satge iam still learning how to use it and what to look for and what it can do.. thanks for the help

I don't know the differences between different scan tools, but I do know that some tools can't pick up all the faults. I did a scan using my dad's scan tool (he's a mechanic) and it didn't pick up any faults at all, yes every time I drove the car it gave me the SVS warning.
Oil pressure switch fixed that though

If the Service Vehicle Soon warning appears, and you don't have access to a scan tool, there is a simple way of determining whether the oil pressure sender is at fault.
Unplug the wiring connection from the sender. If it's full of oil, the chances are good that the sender will be the culprit behind the service message. If the connector is dry, the fault could still be the sender, but leaking oil senders is such a common fault with early Alloytecs that it's worth checking for the oil leak anyway.
There is a seal within the sender that is designed to keep the sensor mechanism clean and dry. The seal fails pretty early on, the oil gets into the guts of the switch and it faults out. The oil, which is under pressure and very hot, is then able to exit into the connector. There is a seal around the connector so the oil is mostly trapped within the connection and quite a bit will escape when you unplug the wiring. Unfortunately, cleaning out the connection doesn't fix the problem but if oil is present, the switch is stuffed anyway and is very likely to be the cause of your SVS message.
i unplug the connector from the sender and i have no oil in there.. have read on the forum that a few have had there oil pressure sender show up the SVS fault... and have had to replace it..
