Volvo V70 - Recent Questions, Troubleshooting & Support

This is actually very simple, if a bit messy.

Put a couple of rags under the sensor, remove the connector from it. Undo the cap on the Schrader valve. It's on the fuel rail on the opposite side of the FPR. Press the center with a rag over it and let it soak up the gas that comes out.

Then go back to the FPR and undo the T25 screw from it, then with gently pull it out while twisting it back and forth a little and let the rags soak up the mess under it.

Then stick the new one in, tighten the screw, replace the connector and turn on the ignition a couple of times to push fuel up to the rail and pressurize it, then start the car.

My sensor failed by 'hiccuping' once in a while. It would spike the pressure to 120 psi, then drop to 20 psi, then normalize at 43 psi again, all within a few seconds.

The passenger seat has a occupant weight sensor in it. If she placed her purse or anything in it, the warning will come on. Either fasten that belt or remove any objects you have in the seat. This was my very first thought when I read your question.

This could be your IAC valve, or idle air valve which is supposed to open fully when the car is put into drive. If not, engine will stall out. Clean throttle body, as well as the IAC valve with carb cleaner. Turn IAC upside down so carb cleaner does not enter the body of the valve or motor end of business.

yes. the light indicates a fault in the abs system (it will store a code which can be retrieved with a code reader), and the abs system will be disabled until repaired. your brakes will function normally, but you will have no abs feature.

The tracs off light comes on automatically whenever the ABS light goes off. Each of 4 wheels has an ABS sensor. The ABS light usually comes when any one of these sensors go bad. It could also be the ABS computer but the computers usually last the lifetime of the car on Volvos. Then, of course it could be some wire spliced somewhere in the ABS circuit and that would be something very difficult to find where the short is. But try the sensors, they are usually the culprit.

I found it necessary to try two of the the fixes listed before I solved the problem. Here's what I learned, as it relates to my 2000 V70:

1. The lock button on the shifter WAS stuck in the depressed mode. So I squirted a bit of WD-40 and--presto! It was released. But my problem wasn't solved. On examining the button action a little more, I noticed it it wasn't FULLY freed. So, another squirt of WD-40 and a few more press/releases, and---PERFECT. BUT the problem was not solved.

2. I next tried to "lift" the "shift override" button using pliers with gentle-to-moderate pressure so as not to break the plastic. It did lift a little, but still no solution. So I squirted a bit of WD-40 into the space around the button and pushed the button several times to "work-in" the WD-40. No luck. In fact, the button seemed stuck in a depressed mode even more.

3. Finally, to the SOLUTION! Since I could no longer get a grip on the button, I introduced 2 thin-bladed knives to barely exposed opposing side surfaces and pried the switch-button up. Still, no luck, but going back to the pliers and gentle/moderate pressure, I was able to pull the button up, and----SUCCESS!!!!

Notes: I am surprised at how much travel there was in the button--a good 3/16" it seems.

I don't know what caused the button to seize in the depressed state. I never use it and I don't think that I've ever spilled anything on/in it. But its horizontal position just begs for this kind of problem.

Unfortunately there is not an easy answer for this. Volvo remotes are difficult to program and most mechanics and / or locksmiths won't touch them.

My company does sell these remotes, but like I said above, it is difficult to find anyone to program them. If you take it to the dealer, they will want you to purchase the keyless entry remote from them, and of course charge you a huge fee!

If you can find a locksmith or mechanic in your area to program a keyless entry remote for your Volvo I would suggest purchasing the remote online and save some cash.

This solution is for every car owner with an ABS problem (e.g. Brake System Warning Light).
Does the...
1)ABS warning light comes on occasionally while driving, warning light turns off next time you start the car, eventually the light comes back on if you drive long enough
2)ABS light comes on seconds or minutes after starting or even moving your car
3)ABS sensors have been replaced, ABS controller has been replaced, and ... the problem returns, sometimes soon, sometimes later
4)ABS warning light refuses to act up in front of your mechanic
5)ABS mechanic has no idea what is wrong
6)ABS brake have no leaks to be found, the brake fluid levels are normal and the brake pads pass inspection but the light comes on

My solution will not solve all ABS system warning light problems, but it may solve very many and save many dollars.
This solution just isn't Standard Operating Procedure in our day to day service repair shops as it is time consuming fault elimination. Why is it overlooked, who knows? It should also, in my experienced opinion, be the absolute first thing checked, by the book, before any sensor, control module, brake fluid, brake bleeding, whatever your mechanic suggest... the list goes on for some car owners. The point is, if this isn't checked first, all bets are off for the DIY or even the certified mechanic.

To get my point across to every car owner and MECHANIC will require GREAT effort on my part otherwise this information will be ignored. Now, back to my point, unless this check is made before any car "computer" throws an error code is taken into account, then that error code can be misleading. No ABS red warning light on the dash of all cars or trucks everywhere can truly be CERTIFIED in testing if this process isn't first completed. The odd exception might be the ABS control unit was on fire, you drove the brakes down to metal or some other freak accident. Here's where I say, "for just $9.95, you, can buy this instruction book". Nope this is FREE and will save many people from having nightmares considering the millions of car owners.

Have you ever heard, "A chain is only as strong as its weakest link"? Well, in the real world, ABS errors are almost always misdiagnosed in first repair attempts. The very first thing that should be performed is a visual inspection inside the engine compartment and brake area. Unless there is an obvious loose wiring harness plug, a lost kitten, distorted/bent brake lines, worn out rotors or brake pads, or something else screaming for your attention; then close the hood and step away from the vehicle and put down that silly diagnostic computer. So, now that the hood is closed, we are going to jack up the car and take off a wheel. Once a wheel is off, we need to disconnect the brake caliper and hang it to the side out of the way. Yes, this is usually a painful, very greasy and dirty process; front wheel and four wheel systems are even more fun. Start with the front wheels and work your way around. Now, and only now is it possible to check each Wheel Bearing Torque value. However, just checking the torque with a push and pull of the rotor disk isn't always sufficient. The hub axle bearings and bearing seats need to be inspected, bearings repacked and then precisely torqued. And when I say precisely, in some rare cases that can mean putting all the parts back together, driving the vehicle, tearing the wheel back down and checking the torque settings again. In some cases; hub, axle and wheel bearing assembly just can't maintain this torque value and still rotate properly because just one of the 3 parts may have some flaw, and this leads to rotor movement. It is also very easy for an experienced mechanic to get it wrong. So, it is good to do it right the first time but that also does not mean it always can be done correctly the first time. As good as any mechanic or auto production line worker may be during assembly of these components, all of these bearing components will never "seat" the exact same or show identical performance. They just try to do their best with what they have.

Basically, the ABS electronics are not the weakest link in most cases. If you have proven beyond doubt that the axle bearings are as close to 100% of factory torque settings and the bearings are healthy and lubed, then the weakest link has been removed. Only then should an ABS error code be used to diagnose a possible electronic component failure. All that this axle bearing nonsense means to those still wondering is that the ABS sensor ring will no longer be deflecting off axis as it spins or sits inside the rotor hub. If the hub/ABS sensor ring tilt off axis just a fraction of an inch on some vehicles, the gap between the sensor and ring is affected, and this will trip the ABS warning light. These ABS systems were designed to operate within a specific set of tolerances and unfortunately the bearings in your axles will not always cooperate. A pot hole here, a curb there, too much hard cornering and braking; sometimes that is all it takes to just slightly loosen an axle bearing and have virtually no noticeable effect.

That is my 2 cents the ABS problems, thanks for reading.

There is a ten amp fuse under the bonnet for the rear wiper, mine popped the fuse during the recent cold snap. The relays all checked out.

The light is an engine malfunction light and is registered by the vehicle's ECM (engine control module), the vehicle's onboard computer. The computer is set to read variables from the car's many sensors. If a sensor gives a reading that is out of spec, it lights the light. Under the dashboard by the driver's knee is a socket that is called an OBD11 (onboard diagnostics version 2) port. When a OBD11 code reader is connected to it, it gives a P Code and this tells what is wrong. Garages will normally read the code for free in the hope of getting the work. Connecting and reading literally takes less than two minutes. I have a reader called FIXD which relays information to my iPhone.

Hi rodknob,

What are side lights ? are they a parking light ?
Think you need to wire the side light switch feed wire to a relay and have the relay power on when the car has Accessory Power from the key Switch accessory wire.
Using a delay relay means the lights can stay on for up to 660 seconds after you turn off the car accessory key switch.
Did a car with a normal relay off accessory wire as I use to forget the headlights and flatten battery.

Or you might be able to use
but you would need to ask them how to wire it to the headlight switch and if it turns on the headlights in the dark or inclement weather.
Like my
You might need to use a relay to feed the power to the headlight switch depends on current involved .
Holden commodore cruise does this as a standard feature via an auto headlight setting on the headlight switch..
