Question about 1999 Volvo S70

1 Answer

I had my 1999 Volvo S70 (GLT) diagnosed a few times already, and these codes keep coming up: P0756, P1618. I know that these are just generic codes, but was still wondering if I could get some help. D

I have an issue with my 1999 Volvo S70 GLT. It has over 250,000 miles. The problem seems to be with accelerating. After driving about a mile or so, it starts to slip acting as if it's in neutral. The engine continues to stay on though. After waiting a few minutes, I'm able to drive it a little more before the problem occurs again. I've taken it to several places to get it checked, and they all say the same thing, which is to get the entire transmission replace, which would cost about $2400. I'm pretty limited financially, so I'm really hoping this is not the only solution.

SOURCE: check engine light

Most check engine light faults are related to a vacuum leak in the system. It could be as simple as a loose gas cap. In my case, and the majority of other S70's, there is a small vacuum hose elbow, located out of sight from the engine manifold and behind the engine thermostat housing, that has deteriorated and is most likely setting the code in your vehicle for a fault. It is not easy to get to and will take some effort to replace. You can go to Autozone and they can read the code for you to see if you're going in the right direction. If it is a gross vacuum leak as determened by the code, then look a the rubber elbows/hoses in the charcoal vapor canistor vacuum circuit. Check out some of the forums such as Mathews or Bay13 for technical inof on the actual repairs.

SOURCE: 98 volvo s70 stalling out, then finally after a day wouldnt start

If the air pump system is setting a fault, then the check valve is probably bad. If it is not addressed, eventually exhaust gases can run back through the air hose to the air filter housing and destroy the MAF sensor, causing these types of problems.

The fuel pump also fails and is a more likely cause of the stalling, and it wont set a code.

No the volvo does not have a servicable filter, The best thing to do is to flush new fluid through the transmission periodically, replacing all of the fluid.

Go to ebay, find urself a ABS Moudle rebuild. 60-80bugs. put it back on. It ll slove ur limb home mode, speed meter drop to 0 when driving. flashing arrow. Contact volvo, buy urself a new ignition antena ring, 50bugs. and once again. look for DIY guide for installation. I replace both of them myself for less than an hour. u might need to buy some special torx for abs moudle tho. but it wont be a big deal. Hope it helps you.

Hello, I have a 1999 Volvo s70 2.4 engine my check engine light is on and I have a yellow arrow flashing. After check engine scan im getting back codes P1618 and also P0717 what does this mean?

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.

ETS light is on on my 1999 S70 GLT

The ETS is the "elecronic throttle system". You either need to get a software upgrade for it, most of the time it wont take. More than likely you will have to replace the throttle body. I would bring it to the dealer. Unless you have VADIS there is nothing you can do. VADIS is what the onboard diagnostic computers the dealerships have for diagnosing your car.
