FIXED my SAABs P0089 Fuel System Code for Under $40!

In this video I discuss the P0089 check engine light code and what it can mean for your Saab 9-3. While the code comes up for a fuel pressure regulator, their may be an underlying fuel pump issue. Follow my steps if this code constantly comes up and change the fuel pressure regulator. If that doesn't fix the issue then look at testing the actual fuel pressure and possibly replacing the fuel pump. Be sure to like, share and subscribe!

As you suspected and another comment stated, this really is a fuel pressure sensor, not a regulator. Our fuel system is controlled by a fuel pump module that is located under the passenger seat, but I think it rarely gets faulty, except when there was some sort of water leak in the car. As you have a Tech 2, you can view live data of the fuel pressure, but it can be done with a simple Elm327 scan tool too. When my fuel pump started thinking about the afterlife this is how I found out. When driving normally the fuel pressure should be around 3 bar and when you floor it, it should go up to about 5 bar and mine was dropping to 2, instead of going up. 😃 That’s my experience with it, hope it helps somebody

[@WeakestofWeeks]

Thinking about the afterlife 😄 love it. Very good info! I'll have to play around with the tech2 and see what I come up with. Thanks friend!

I got a 2005 Saab 97X with the 53 engine work take engine it came up with code came up that the Black box on the throttle body is bad and I want to know if your video on how to replace

[@peterdeal5631]

Just followed your video and replaced the fuel pressure sensor with a new Bosch one and it worked! I have a 2007 V6 2.8 Sportwagen with only 53K miles on the clock. The local garage charged me £100 to identify the P0089 Code! Peter D.

[@govind20231]

Yes, this is essentially a fuel pressure sensor than a regulator. Saab uses a returnless fuel system where the fuel pump actually regulates the fuel pressure. I had changed the fuel pressure sensor too sometime back, let's see if it helps in keeping the code from coming back anytime soon.

[@WeakestofWeeks]

More of a fuel pressure sensor than a regular makes sense! Thanks for commenting.

[@tonyq4358]

I have the blue Aero just like yours. When I purchased the car, it had the P0089 code and it would not go away. I had to replace the fuel pump the day I got it to pass smog in CA. I also replaced the sensor upfront, since then, it came up once on a really hot day, hasn't come back since. I've helped a few friends out with this code and it's always been the fuel pump in my experience.

[@DanielKarjala]

I know the fuel pump is not cheap to replace. My code in the past 1.5 to 2 years just does not go away after spending over $2,000 on it. How much to replace the fuel pump (parts and labor)? Help!!

[@deshawzn79]

@@DanielKarjala very cheap I just did mine takes all of 20 mins if you don't have issues taking off the lines or the fuel pump.

[@SaabAtical2009]

good video. the V6 has a 'Fuel Pressure SENSOR' and the 4Zyl has a 'Fuel Pressure REGULATOR'

[@mustardstain504d6]

The fuel pressure sensor is on the rail on the 2.8. The regulator is on the fuel sender.

Oh, first! Where my kewpie doll? Lol

[@Peter-sm8bj]

Focus 1.0 Hi mate i just managed to into live data fuel rail pressure is 1300 psi And also the fault code i am getting is p0089 Fuel rail oressure regulator 1 performance its says would that be the high pressure fuel rail sensor ? Maybe that sensor is gubbed Any idea mate ? thanks

[@moreryjm]

Thanks!

[@WeakestofWeeks]

Thanks friend I appreciate it!

[@philliparthur8672]

Great job I wouldn't have thought about that. Very funny and don't change what you're doing, be yourself. Hopefully its fixed. Question, does your car act up when gas changes from summer to winter or winter to summer? Mine has last fall and this spring but just once. It's like it learns the new mix maybe? Anyway thanks for doing these videos.

[@WeakestofWeeks]

I don't think performance changes much between summer and winter blends for me but I usually don't drive the car too hard. I do notice a difference in the estimated MPG's though. I've never really manually calculated to actually tell a difference lol.

[@philliparthur8672]

@@WeakestofWeeks I was just wondering, maybe my Saab is a diva? Lol Anyway thank you so much

[@philliparthur8672]

@@WeakestofWeeks I wanted to tell you the last time I went to the junkyard they had a 2003 saab 9-3 that was picked over pretty well but I checked it anyway and I got door sills with metal inserts that say, Saab ARC. I couldn't pass them up and paid 4 dollars for both. Now instead of my plain black ones I have those in my car.

[@WeakestofWeeks]

@@philliparthur8672 Cool find, and cheap! Are those sills held in with clips or double sided tape? Believe it or not I've never removed those before lol.

[@philliparthur8672]

@@WeakestofWeeks three white pins, when it popped I thought it was broken. The three pins fit into three holes my 07 pins were bigger around so I had to switch them. They slide out like on your car door panels. If you want to remove door sills lift at the bottom where the rubber door seal touches the sill. Pull up and it pops loose (very loud pop). I hope this helps.

[@jonasuebel9125]

What about a clogged fuel filter? That should be a possibility too. Great video btw

[@WeakestofWeeks]

Great comment! Fuel filter replacement is also a great recommendation. Unfortunately, US spec 9-3's never received a serviceable external fuel filter. I should have at least mentioned that so thank you for bringing up!

[@DanielGonzalez-gr6xz]

What would cause a high pressure in fuel rail? Forgive me but I forgot the code it thru, it also thru the pressure sensor and since I changed the pressure sensor the code was cleared but still runs laggy and sometimes doesn’t want to start

[@agresorxf]

Did u had code P0192 before ?

[@jettehhawk1732]

Have you ever had issues with your fuel level reading incorrectly on either of your 2.8 Aero? If so did it require a full fuel sender replacement or just a level resistor/float? Can't seem to find info on the 2.8, only the 2.0.

[@WeakestofWeeks]

Oh yes, I've had the fuel level issues on one of my 2.8's which required either a fuel pump or sender replacement. I replaced just the sender and used Dorman #911-016. So far it's been in the car 3yrs and still going strong.

[@jettehhawk1732]

@@WeakestofWeeks thanks for the I insight! My fuel pump is otherwise good so I'll be ordering the part number you've used.

[@billywill123]

If your getting the p0089 code its almost always the fuel pump or fuel filter inside the pump module . 80% of the time running 2 cans of seafoam or similar fuel treatment one after the other will fix the issue . If it does not then the fuel pump bypass valve (built in to the pump ) is failing or the filter is plugged up causing the bypass to open . This fuel system is returnees and runs off a pwm signal . So if the fuel pump control module (located under the passanger seat) senses a lower pressure at the fuel rail then requested the light comes on. The car almost always runs perfectly fine . Hope this information helps.

[@WeakestofWeeks]

Really good info I appreciate it! I assume the purpose of the seafoam would be to unblock any junk in the internal filter/strainer or blockages within the fuel lines? I find it odd US spec cars didn't get the serviceable external fuel filter. I'm definitely intrigued by the built in bypass valve so I'll have to do some research on that. Thanks for your comment!!

[@WillRobinsonDanger]

@@WeakestofWeeks What's up my Saabers!!!!!!!!! For my 9-3 v6, I am about to throw in the tank an upgraded fuel pump, Walbro 255 LPH pump. The actual pump, I believe, has been inside the car since the beginning. At the same time, I will be changing out the fuel pressure sensor. Ain't nothing like a little extra insurance.

[@joshgroth]

Agreed. It's likely the pump on the way out. You can buy a cheap Amazon basket and swap in the filter from it into your stock basket. I've heard that Orio will begin supplying drop in fuel pump baskets for all 2.8s soon

[@alexprag2866]

Haven’t had this code for a while, first time putting 89 in my car while running Maptun stage 1 and the code is back :(

[@d4ve587]

Yes yes but where can I buy that hat 🤣💪😎

[@WeakestofWeeks]

Next giveaway? Hahah

[@DanielGonzalez-gr6xz]

What would cause no pressure to the rail if pump, relay and regulator is replaced

[@WeakestofWeeks]

Could be a bad or clogged fuel pump

[@DanielKarjala]

My 2008 Saab 9-3 Aero has been incessantly showing the P0089 (I use my FIXD car code reader to reset it) and had it worked in by a local Saab shop who has been around for a while (but the owner is moving back to Seden and retiring)... then I took it a very well regarded shop who tested the fuel pressure and found no issue whatsoever. He also test drove the car many times and the light never came back on until I drove it off and the next morning it came back on... argh!!! I added fuel line cleaner etc, and the light comes on several times a day (after I reset the error light). It will not stop! I live in California and need to have it tested (every other year) this year to have it reregistered. In trouble if we cannot stop this error! HELP!!

[@JS-ri2rx]

Hi did you find the fault. Im having a similar issue and desperate to find the fault as test due in 2 weeks.

[@MAXMAX-co8yu]

hello, I still have error P0089 after replacing: spark plugs, coils, fuel pump relay, fuel pressure sensor, today I replaced fuel pump with WALBRO, again error after second ignition of the engine while idling, after 30 seconds from engine ignition. I do not know what to do!!! 😱😱😱

[@WeakestofWeeks]

Hard to say. You can try changing out the fuel pump model underneath the right passenger seat (at least on a US spec car). Outside of that maybe you kinked a line installing the Walbro pump?

[@MAXMAX-co8yu]

Hi, no bent pipe, error P0089 always present, under the passenger seat I don't know what it is, you don't have any photos? thank you
