Question about 1998 Volvo S70

1 Answer

I have a 1998 Volvo S70. The Malfunction Indicator Light comes on when you run the car from cold.

Once the engine is really warmed up and you reset the computer the message does not reappear until the engine is cold again. We have replaced the CVP lines, pugs, leads & rota, catylitic converter and O2 sensors (both). Does anyone have a suggestion please. Chris Jones

Check the B+ cable. If you remove the fuse box cover in the engine compartment (on the drivers side), and you'll see a post with a nut on it, securing a group of red wires. The connector should be a clean copper color. If you take it to a shop, have them perform a voltage drop test on the cable. If it is corroded or burnt, replace that cable!

Change the IAC the idle air control. You may be able to clean it and put it back on.

Hi, there are a number of trouble codes associated with the O2 sensors. Some indicate a sensor failure and others indicate a different problem. Can you tell me the trouble code you are getting?

Thanks for choosing FixYa and welcome to the site. OK, bank 1 is located on the same side as the number one cylinder. Most times this is the driver's side. Bank 2 is located on the passenger side of the vehicle, which is opposite of the #1 cylinder. Sensor 1 is before the catylitic converter and sensor 2 is always located after. So for your answer, it is located on the passenger's side before the catylitic converter. That is the location of the bank2 sensor 1 O2 sensor.

Hello. I have a 1998 Volvo S70 sedan (stick shift) and the air conditioning is blowing out warm air. It used to get very cold. Do I need to replace my air compressor valve and dryer? Or what?


a full service of the system should fix the problem, and replacement of the evaporator \ dryer should be done.

You have air in the cooling system.

How to turn off service engine light on 98 volvo s70. just did oil change


There is unfortunately no "trick" for this. You will need the service light reset tool. On some other Volvo models it was possible to reset the light by holding down the reset button for the trip meter and turning the key to position II - keep holding the reset button down for about 30 seconds.

Cold Start Knock


That's actually pretty normal. It's just the engine warming up. Even my friend with a late model Acura has the same prolem so she warms it up before driving. I've heard experts say that warming up your car is just a waste of gas so I presume that the initial knocks are not to be worried about. Something to email Click and Clack on NPR about but I really don't think it's an issue. When I've had two cars run into the 200,000 mile range it didn't seem to be an issue. I always changed the oil before or at about 4k miles.
Take the car out for a long drive and enjoy it. And don't worry.
