Volvo Fuel Pressure (ECM-2900 / P0089) - Repairs

The new Bosch Fuel Pump assembly is in, so let's install it on the Volvo S60 and see if our diagnosis was correct!
Procedure is a bit tricky, but with a bit of creativity we get it done right.
Verification of the ECM 2900 / P0089 code repair included, of course :)

Ivan tie a string to the hose that goes to the other fuel pump so you can pull the new one to it before you pull it out.

[@jannepo]

Two thumbs up for this tip!

If he was a sailor or electrician he would of known that

[@codywichman213]

uwas about to say the same thing, the hole in the tank is about 2inch wide lol

[@wwdiesel]

Agreed, I was going to suggest the same thing. Some small braided rope is your friend when pulling cables and hoses, especially if you ever have worked on fiberglass boats and have to pull wires and cables to replace them.

[@CarlSutton]

I yelled that to him as he started pulling it out... guess he didn’t hear. 🤠

[@richard1835]

Pulse width modulated fuel pumps with all the associated control modules (ecm,f.p.m. etc..) and sensors will be impossible to diagnose without the proper equipment which Ivan has. Great job Pine Hollow. Thank you

[@lanzengineering5272]

The best way to visualise a PWM Signal is to hook up an Oszilloskop. Or some Multimeter offer to use a DWELL function. The % indicates the PWM on / off cycle.

[@willemstreutgers1154]

Free Sunday tip ; use anti seeze on the bolt at the fuel filterclamp. They will freeze often. Nice job Ivan.

[@15farcry]

I have an 06 XC70 with the EXACT same issue. Runs fine, accelerates fine, but has a cel with that code. Was never exactly sure what the issue was. I suspected fuel pump along with many other things. Now you just confirmed the very issue! Just wanted to say thankyou for the high quality and very helpful content you upload! Subbed!

[@oluwanifemiogundeko7132]

Did the cel affect it’s smog test? I have an 04 s60 2.5t with the same issue.

[@15farcry]

@@oluwanifemiogundeko7132 Not that I'm aware of. The CEL comes on as soon as the pump runs at a higher duty cycle than normal. Meaning your pump is starting to get weak.

[@russellstephan6844]

As others have mentioned... When I saw you start to pull the old sending unit out, I thought, "Uh, he needs to have tied on some kind of string and pulled it through so he can *_then_* use the string to pull back the harness/hose of the replacement." Yep... Such is the way it goes. You'll know for the next time, for sure.

[@buckhorncortez]

I owned an S60 T5. When the factory warranty was coming to an end, the service advisor told me, "Buy the extended warranty, it will pay for itself." It did.

[@engineeringpunk]

I had to do this same job on a Nissan Rogue a few weeks ago. Very similar setup. The service info for that thing said to tie a string to the wire and tube at the secondary sensor before yanking out the main fuel pump hanger so you could use the string to pull the tube and wire for the new one down and over to the second sensor. Glad I read the service info before I just started yanking stuff. No one in my area even stocks ni-copp brake line. It's special order ;-)

[@Gilboy64]

I was saying the same! When I was pulling out at old wire I was thinking you should've tied something to it to be able to pull a new wire back

[@douglasjreynolds]

[@rafflesnh]

Almost every European car you work on, Ivan, you describe as being too 'fancy'. And yet, you almost always seem to find something to admire about them too, as in the dual pump layout on the Volvo being able to pump fuel from one tank to another as being 'awesome'. Rather like an aircraft in fact. Deffo a love-hate relationship going on there! ;-)

[@douglasjreynolds]

Well, European cars have a lot of engineering that goes in them, no doubt. It can make it tons harder to diagnose though.

[@jannepo]

​@@douglasjreynolds not really, you just need to spend 90 USD and order Volvo Vida and DICE from China. The interface is from the same factory and looks the same as the one Volvo sell to their dealers for mere 750 USD. Software is a pirated copy and works only offline, the original is something like 3000 USD / yr. All manuals, all information, one of the best two directional scan tools and absolutely detailed instructions for each fault code, when it sets, what is wrong, where the faulty component is and how you change it. No other universal tool comes nowhere near VIDA. Witi it you are the Official Volvo repair shop, minus the SW upgrades. See yourself: kzbin.info/www/bejne/e4msomWJqLVootE So it is not hard, the US general purpose tools are just not enough. With the right tools, it is easy to diagnose and repair. I have my VIDA on a 2003 Dell XP laptop for my Volvo V70 2.4T 2000 and I'm loving it.o

Smart move replacing the filter Ivan. Why go through all that work and have a dirty fuel filter ruin all your hard work. The old one may have been good but it doesn’t take much dirt to ruin or affect a new pump or transfer pump. Makes ya feel good when all your efforts pay off in the end. Nice work Ivan

[@fieldsofomagh]

The pwm% was the real giveaway at idle having elevated numbers for a reasonable output. Don't come over to Europe for an easy time. The information is very reduced and expensive. The attitude in the States is very repair friendly and reasonable priced.

[@willjr2520]

Thank you for this video. I recently had the same P0089 code. With a 16 year old original pump and 125k miles, I finally decided to change the fuel pump. It was the last thing on my "to do" list for the S60 T5. What a difference! Very smooth with a faster acceleration and hopefully better MPG. Thank you again!

[@jb_bmwrepairlyfe4704]

Great job on your diagnosis! This is actually not a common failure for Volvo. Usually around 200k miles is when fuel pumps fail on those cars. The pwm design helps with longevity.

[@jaydenholland6748]

Some cars use 2 pumps because of the shape of the tank to make sure the fuel is taken from one side of the tank to the other and then pump to front of car. More parts more failures more landfill!

[@jannepo]

About the bonus part: Yes there are two fuel level sensors, computer calculates how much there is fuel left from two sensors and turns the fuel gauge needle to the right position. I once ran out of fuel with my V70, when the fuel gauge was showing half tank. One of the sensors was stuck to full and I ran both tanks totally empty, because the gauge was showing 1/2 tank, but in reality both tank sides were empty. The needle was not stuck, it just moved a half speed down from full and I did not realize that. So even with a new car - reset you tripmeter when topping up the tank. Fuel level sender froze in freezing weather due a few drops of water in the gas i filled from an underground tank.

[@fingigs]

Thanks Janne, I had the same problem.

[@Garth2011]

Lots of sedans have those "Saddle" fuel tanks. The fuel level sending unit is typical on one side and the fuel pump module is on the other. Easy to get to, no removing the tank. Just have to be careful and always have some of those "pigmatts" on hand to catch any spillage. I am amazed that these fuel pumps, which wear out way too soon, are still used by vehicle manufacturers. You'd think they would improve them to go a good 150,000 miles or more but they don't. I'm almost sure that just the fuel pump itself is sold separately which can save on cost quite a bunch depending on the labor charge to swap out the old one. Stay away from Airtex fuel pumps. Delphi is good.

[@phprofYT]

A big fat guess on the two pumps and all the complications. Low fuel tank and high speed cornering might cause fuel starvation. This system might be to mitigate that possibility.

[@baxrok2.]

Just like the BMW's.

[@thebigmacd]

It's because the fuel tank is a saddle tank over the driveshaft.

[@for2utube]

Pump side gets almost all fuel - keeps it cool. Don’t attribute to genius that which can be attributed to cost cuts.

[@NoWr2Run]

" WHY 2 FUEL PUMPS & LEVEL SENSORS " Because some FOREIGN YO YO who sits behind a desk all day & NEVER WORKED ON A VEHICLE IN HIS LIFE, DESIGN IT THAT WAY. GREAT DIAG. SIR IVAN AS ALWAY & DAMN THAT WAS A BIG FUEL FILTER. Henry from N.E. PA.

[@jannepo]

S60, V70 etc have a "Saddle tank", because AWD models have a rear driveshaft running through the lower part of the tank. Without the transfer pump, you would only get a half tank gas out from the tank (V70). Simpler solution would have been putting a hose at the bottom of the tank from one side to other, BUT if that hose would be damaged in a accident, it would leak out the whole tank of gas and cause a serious fire hazard at the accident site. Like you burning in your car. When you use electric pumps for transfer and and delivery, you can stop the pumps when accident happens and all the hoses outside the plastic fuel tank are not pressurised and do not spew out gas if ripper or damaged. The plastic tank has been designed to sustain a lot of damage before puncturing.

[@stealthg35infiniti94]

Good job Ivan ! As you started pulling the old pump out, I was saying to myself, tie a string to the end so you can retie it to the new pump. Then pull back on the string and the new parts come back.

[@PineHollowAutoDiagnostics]

Haha next time I will 😁

[@adamtrombino106]

Interesting that as worn out as that OE pump seemed to be, that it never set a lean code. I would've been curious to see where fuel trims were, just for giggles. Oh what fun replacing that looked to be !

[@roadshowerun1770]

Truly a superior effort Ivan. The Volvo. Not so much. I could understand the the other company, SAAB, with a complex fuel management system. SAAB makes jet fighters. Volvo has sunk to new lows. They used to be the "buy it and forget it" company.

[@themechanic6117]

nice work as always. that new pump was kicking ass

[@stephendee7839]

As you pulled the cross-tank wire out without a return wire to pull it back already connected, I thought out loud "that's a mistake." And it was! It's really cool that volvo figured out a way to detect fuel pump imminent failure before leaving the owner stranded. Complexity but great benefit.

[@thierryblanc9000]

My 2001 S60 Did not lose fuel pressure when engine off. It had also external fuel filter next to gas tank.

[@SmittySmithsonite]

Wow, that looked like a HUGE PITA to fish those lines over to the other side! How aggravating. This reminds me of a Ford Mustang setup ('06 or so). Difference was, Ford uses one pump to do the same job, siphoning out of the other tank half. Just more things to fail! That's the way they engineer 'em today. Huge difference with the new pump! "Disconnect! Disconnect!" HAHAHA! I was rolling!! :D

[@odin-eliottodinson7330]

I used to work at a Volvo Dealership. I remenber the first time I did the same mistake, partly filling the tank and just pulling out the transfer-hose.... That day I learned to plan ahead, and tie a string to it so it wouldn't take the rest of the day (or stink out the car with gas). Actually we also had a pneumatic tank-draining pump. But that's the best way to learn, f*ck up once, and make the experienced call next time. Good video Ivan.

[@HUBBABUBBADOOPYDOOP]

[@PineHollowAutoDiagnostics]

[@Dogpool]

If the information was more clear on this code , what you really needed to know was what duty cycle it should be at to what fuel pressure. With the info you have given us it turns an hours long diagnostic into just minutes. Thank you

[@Dogpool]

So I just did this job on an xc90. Very similar setup, the range was not as bad as yours of high duty cycle. On this one the duty cycle was only at 43 percent at idle and still set the code. After a new pump it went down to 35 percent. So it only takes a slightly worn pump to give that code.

Yes, sometimes mechanical fault can cause EFI fault codes, very large long term fuel trims, etc because a faulty fuel pressure regulator caused a 25% long term fuel trims,a P0171 & a P0174 lean code as the fuel pressure was at 51 PSI instead of 58 PSI where it's supposed to be in my car !

[@sebczajna700]

[@jorgefernandez-mv8hu]

Nice job on that diagnosis. At least you didn't have to drop the tank to get it out. Overly complicated system. Now you know that if you power the pump directly from the battery a good pump will get you very high pressure and a soon to die one will not get to the 70psi the computer needs. Great Job.👍👍👍

[@fredandcheryl94]

I just love firing the Volvo parts cannon. Parts guy 35 years!

[@MrXyzasdf]

Once aspect to keep in mind when dealing with any pumps. Pressure does NOT equal Volume. In general when you have a two pump system like this you replace both pumps.

[@stephendee7839]

The between-tank pump wasn't throwing a code and clearly Volvo is monitoring all the pump efficiencies. If the other mechanism was hard to get to, I'd probably agree with you, but in this vehicle, it looked fairly simple so no expense needed at this time.

[@scotttiller4660]

"Volvo doesn't give good info" wrong, and that includes pretty much all manufacturers. The after sales companies like alldata and Michell ect... don't buy that info, because they are cheap asses. One of my issues with after market info suppliers. Great info ivan! As always.

One thing to note on these models P80 cars, the ECM pins can get out of alignment and can caused weird problems, I had one that was calling for throttle body and alter on for the air meter. Realign the pins and it went away, too many pot hole hits.

[@jdtractorman7445]

I was going to suggest it but quite a few others already have, about fastening a string to the old transfer tube before pulling it out. It works great. I did that trick when I was replacing the wiring harness on my boat trailer and it works like a champ. Just curious Ivan, what is the ball park cost of that pump? Three hours is justifiable for this repair with diagnosis and replacement time.

[@don2deliver]

My coworkers had replaced one of these pumps and the car ran again, but the customer was not happy. The fuel trims seemed reasonable but the customer was describing a lean fuel condition under load. I put a mechanical fuel guage on it and the needle started dancing after running a few minutes. Another replacement pump was ordered an upon replacement for the second time I noticed the feed tube for the fuel bucket had gotten knocked off on the first installation. Which was the causd of the complaint.

Pretty sure that secondary pump is just a transfer pump. Since these are 4 wd, the tank has a channel through it to accommodate the rear drive axle. The pump will move the fuel from the opposite side of the tank to the pump side. So i don’t think it has anything to do with the pressure , unless you were about out of fuel.

[@klstrucker930419]

May faulty fuel pump cause DTC codes "fuel pressure signal missing" and "fuel pressure signal too high"? That's what I get, I haven't checked with auxilary pressure gauge, but once the engine is running it reads correct pressure values(nominal pressure equals actual pressure). The car has to be started 7 or 8 times before the fuel pump starts at temperatures 25-45 C, if it's hotter or colder- no problem.

[@keltecshooter]

I learned something interesting with the difference between the sensor data and the old school gage , dose that vary from altitude ? Similar to Barometric values ?

[@sjn7220]

keltecshooter It's just gauge vs. absolute pressure. Gauge pressure subtracts the atmospheric pressure (14 psi), so it essentially reports pressure above atmospheric pressure.

[@keltecshooter]

@@sjn7220 or is it simply calibrated to zero taking in to account for atmospheric pressure....

[@sjn7220]

@@keltecshooter More or less, but maybe calibration is not the right word as that has to do with accuracy. It just depends what is used as the reference pressure, vacuum or atmospheric.
