Top 10 1998 Volvo V70 Questions & Answers

ABS light comes on with ignition then should go off when you start the car.
If abs sensor does not turn off after disconnecting the battery, then there is a real problem, a faulty sensor or ABS malfunctioning.
When the ABS led comes on immediately after you start the car and stays on usually is one of the relays.
The main one is called surge arrester relay, if it is faulty usually there have been an overvoltage.
There should be two more, usually located behind the black plastic cover of the ABS.
Testing and changing the faulty relay can fix the problem.

If light turns off on startup, and comes back on when you reach some speed, usually you need to check the wheel sensors. You test them unplugging the sensor located behind the wheel and testing it for continuity with a multimeter.
Use Haynes manual to find locations and specs of relays.
Contact a qualified mechanic if you cannot fix it yourself, problems with ABS may compromise safety of the vehicle.

Volvo has issued a recall on the brake vacuum pump which can be viewed at www.automallusa.net/2000/volvo/s40/recalls.html that involves water invading the pump, which would cause noise and braking problems.

Hope this helps, and good luck.

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.

Brandonlo168,

The fuel filter can be located under the carpeted cargo storage floor at the rear of the wagon. Remove the four 10mm bolts, remove the cover. You will then see a removeable plate to the right just behind the rear passenger seat. Fuel filter can be seen through hole in hole. Replaced from underneath wagon. Be sure to make sure lines are fully inserted onto filter. Check for leaks. No smoking, extinguisher handy. Note arrow on filter for correct fuel flow.

Yes, it's the 'pnp' switch (also known as the inhibitor switch) which is on the side of the transmission.

I own 2 Volvo 960s (3 litre automatics) which are similar in many respects ... and have that flashing arrow. It's a well known fault and you don't have much to worry about.

Rather than write it all here, you can read what I wrote as an ebay guide about it at http://reviews.ebay.co.uk/Volvo-960-Automatic_W0QQugidZ10000000003233806

I did put similar info on my website at http://www.glennsmart.btinternet.co.uk/volvo960.html with photos

Though the ebay guide is better ...

If you haven't got time to read it ... forget the flashing arrow and put a bit of black tape over it ... My wife's car has (192,000 miles) had that arrow flashing for 3 years. My car (100,000 miles) has had that flashing arrow since I bought it 1 year ago.

I did change the pnp on both cars ... but you also need to have the computer error reset by Volvo to have the light extinguished. Don't worry ... keep driving.

It may be the gromet for the PCV valve or it could be the spark plug rubber seal located in the valve cover if it is the type of engine that has the wires and spark plugs that go down through the valve cover, if this is the case buy a valve cover gasket with the rubber gromets that are located around the base of the hole where spark plugs fit through and install.

On these cars it's more of a system than just a valve. This will walk you through it. http://www.volvoforums.com/forum/showthread.php?t=33970

Volvo does not provide information regarding DTC P1633 for many of their models.
However, it has been reported that various Volvo engine control modules will produce this code. The code is associated with a missing or inaccurate vehicle speed signal from the ABS control module and may be accompanied by DTC P0722 or P1618.

Possible causes:
- Defective vehicle speed signal to the ABS control module
- CAN connection problem
- Defective ABS control module
- Defective engine control module

Manufacture codes associated with this P code may include ECM-510f, 530d.
