Hey all, I am planning to replace the oil pressure sensor on my 02 this weekend. Since I have to pull the intake manifold to do this, I was wondering if there are any additional maintenance items I should take care of while I have it that far apart. For info, my car has over 100K on it but runs like a champ. Thanks for the input.

 

Changed mine 4 times. 2001 MN6 base coupe.
Never pulled the intake.
Get a deep socket that fits the sensor, a 1/2 inch ratchet, a one foot extension, and a universal.
undo the vent hoses at the back of the engine, and you can see the sensor with a flashlight.
make a clip tool to disconnect the connector out of a coat hangar. make it about a foot long, and bend the end to resemble a J.
Then slide the coat hangar to the connector clip, and gently undo the connector.
Then put a small strip of duct tape in the socket on one of the flats.
Slide the socket over the sensor, and get it seated onto the sensor.
Then put the ratchet on the extension, and undo the sensor.
The tape will keep the sensor in the socket. withdraw the sensor.
Put a piece of tape on a paint stick, and put it on the area where the sensor screws into. get all the dirt carefully away from the hole.
Then put the new sensor in the socket, and without the ratchet on the extension, put the sensor into the hole, and gently screw it in place. remember the engine is aluminum, so the utmost care needs to be used.
Then put a torque wrench onto the extension, and tighten it to 50 inch lbs.
With care, figure out where the clip latch is on the sensor where it is now pointed, and realign the wire to be in that position.
Then with a long screwdriver, put the screwdriver with a little piece of tape to the connector, and guide it in the hole.
Then gently push the connector into the sensor.
put all the hoses back, and install the engine cover.
Should take you 30-40 minutes.

 

I changed mine out about 2 weeks ago, not really a big deal in removing the intake. Just make sure that you clean the area around the oil sensor so when you remove it, will not get dirt in your oil.

Becare ful not to get dirt in your intake head ports if there dirty. When done torque everything to spec and you will be good to go. It is 15ft lbs for the new sensor.

 

the hoses on the back of the manifold are probably brittle and there is a really short one that you could replace with a little longer, makes it easier to hook back up. I would replace the intake gaskets as long as its off

 

I saw a post on Facebook. Another guy was doing the same thing and it was suggested he do it THIS way...



I tell ya....some people

 

Pretty common way to do it IMO. Sure you can do it a bit cleaner, maybe a rubber cover or cleaner cuts, but if you're replacing it 2+ times over the life of the car, it seems a simple but effective solution. Won't see that bit with the cowl on anyways.

 

If you can't do it the proper way then maybe you shouldn't be doing it at all....besides if you're replacing it 2 or 3 times then maybe you're not buying the right one. Oh and one more thing, they do have relocating kits so you don't have to pull the manifold every time.

 

There's a thread on here that shows precisely how to do it that way. I did it a couple years back, and I'll tell ya, that access came in very handy yesterday when I had to replace the A/C vacuum line that comes out of the back of the manifold. You can always make a sheetmetal cover and rtv it in place if need be, or even use dzus fasteners. It doesn't bother me because it's hidden under the cowl, and I like having the access.

 

No need to do a half a$$ job on something so easy

 

I don't know why everyone is so afraid of pulling the intake. It's quite simple, really.

 

When you have the intake off, check the o-ring on the cam sensor. Mine leaked and sprayed a fine oil mist everywhere.

 

took the words right out of my mouth. Ive pulled my intake a handful of times. Only twice for that sensor. First original took a dump around 80k mi and the second leaked around 120k on the new motor. The intake is not hard to remove. Like anything you do on your car, take your time and it should go smooth.

 

To the OP,

It is worth the cost to relocate the sensor as many of us have had the replacement sensors fail multiple times. Just buying the "correct replacement sensor" will offer no guarantee that it to will not fail.......sometimes in a few weeks.

 

Thanks for all the information - some very good suggestions in this thread.

 

I wouldn't cut the cowl but, many have. I did mine without removing the manifold. If I did it again I would remove the manifold clean everything up and check the vacuum hoses .

 

Why work around not taking the intake off?

It's my daily driver, and I can't afford any surprises.
30 minutes vs taking a whole day....................That's the reason.

 

Everyone is forgetting the main discussion. I read that the oil sensor with the bronze fitting is the one that last the longest, not the GM one with the silver fitting.

The bronze can be found at oreilly's

the 4 i changed came from O'Reilly's but with a lifetime warranty, I will continue to swap em out. they are all brass base from Borg Warner

 

Speaking of the cam sensor, is there some "trick" in removing it? When I was swapping my o/p sensor, last year, I attempted to remove the cam sensor, to give me a little more working room, to get the o/p sensor out. I unbolted the retaining screw on the cam sensor, but it wouldn't lift out. I reinstalled the bolt and left it alone, before I damaged anything.....

 

Was probably just seized up nice and tight. I just unbolted the one screw on mine and gently pulled up on the sensor with a lil back n forth wiggling...
