20 Most Recent 1999 Volvo S70 Questions & Answers


This is a gearbox issue. Both codes relate to the transmission. Specifically P0717 is to do with an engine speed sensor that lets the gearbox know when it is supposed to change gear. Have you had any work done recently. They might have disturbed some wiring causing this problem. Replacing this sensor is not a simple task as i believe it is inside the box so requires the gearbox to be removed. There are some good Volvo forums on the internet that will be able to help you and point you to a local independent Volvo garage rather than a main dealer to keep costs down.

Check and clear fault codes if appropriate.

Borrow a code reader from an auto parts store (free) and see if any trouble codes show up (the device will have instructions and is easy to use). That should give you a clue to the problem. Problem could be sensors of some kind. If no codes, could be a clogged fuel filter -- when was it last changed?

On a web search I found several people that had similar weird dash lights/operation issues. Someone thought it might be a faulty ignition switch but that was not it. The success came as follows:
"Alright fixed the problem it was an electrical relay. If you remove the cover of the fuse box under the hood there are 4 large relays. two of them are unmarked as to what they are for but I disconnected them while the car and everything was running and it turned out that one was for the lights and the other was for the interior electrical components A/C, Radio, wipers, etc. I replaced the one that I needed and all is well now. Thanks for the help $20 for a problem that had me ready to sell the car."
Your issue may be similar .. a faulty relay in the fuse/relay box under the hood...which I think is just forward of the driver side wheel well. Usually there is a legion/map on the underside of the lid that tells you what each relay and fuse is.
Good luck on your troubleshooting

Do you have a sunroof? Cars have drainage holes up there that often drain into the door jamb on the front doors and sometimes down the rear pillars and behind the trunk/boot lining and exit the car near the wheel wells. Often, the connection at the top to the pipe comes off at the top corner of the windscreen.

Others have the same problem. Sunroof drain mentioned and how to fix.
