Check seatbelt wire connections and if it has one, the comfort control module, crash sensors and crash module.

I had a similar problem after having my oil changed at jiffy lube. The problem was that they hadn't fully tightened the oil filter, so it was leaking oil when the engine was running. They did it to me on two cars. I don't go there anymore.

If you don't see smoke, you're not burning it. If you don't see it under where you park your car, it's not leaking when the car is parked.

Go snug plus 1/8th of a turn. That is how I was taught and have done for 35 years without issue.

Best done on a lift by a shop. You need a tool to hang the engine from while it is still in the car. The the subframe needs to be removed which involves disconnecting the steering wheel, steering rack, a frames engine mounts and crossmember. Not for the novice.

You need to check for power to the sensor with a volt meter. If you have power then you need to have a professional check it as you will need a lab scope or graphing multi meter to determine if you are getting a signal to the ECU

Throttle position sensor is part of the throttle body assembly. It is not sold as a separate part. You need to replace the throttle assembly. Remove the intake tube, remove the 4 bolts and disconnect the electrical plug. It will need to be programmed by someone withe the Volvo Vida software.

How to fix what? Need more information

1999 Volvo S70 | Answered on Apr 16, 2015


You cannot and I repeat cannot do this job without the line up tool for the camshafts. The reassembly of this engine is set for about 30 degrees off of tdc. There are no marks for the cams to line them up. You need the jig that holds the cams in place. I have 35 yrs working on Volvos as a professional tech. YOU CANNOT do this without the tool.

Everyone always jumps to head gaskets. There are plenty of MINOR things that can be looked at first.
The Volvo 2.3, 2.4, 2.5 Inline 5 Cylinder dipstick tube is known to develop a large amount of condensationin winter months and stop and go driving. What you see on your dip stick is possibly just condensation. Take off your oil cap and look under the cap and inside the valve cover. Is there any thick foamy oatmeal like substance or noticeable amounts of water? If your oil was saturated with coolant, you would be able to see it up there too. Check your coolant for oil. Volvo coolant is typically brown to orange, however make sure there is no sludge. Start the car with the cap off and keep an eye out for alot of bubbles. A large amount of bubbles is a sign of a bad head gasket. A couple here and there is just air in your cooling system.
Coolant, Transmission fluid, and Oil have several places they can mix. If you have a turbocharged Volvo, the seals in the turbo can go bad and cause a mix of oil and coolant. Your transmission cooler is also in your radiator, and if it cracks your transmission fluid and coolant can mix. I believe turbo models have an oil cooler built into the radiator as well.
Overall if your car sounds fine, you dont see oatmeal, your not using coolant and oil in excessive amounts, dont have white smoke, and your turbo isnt whining you probably just have condensation in your dip stick. If you are overly concerned you can send a sample of your oil to a lab and have it tested for traces of coolant. Headgaskets rarely fail on Volvo's, even the old ones....I have seen many that have gone to replace them have not found a failed gasket and end up finding a bad transmission cooler or a bad turbo.

Your transmission will do this if it senses a problem with 2nd gear (or 1st, 3rd, or 4th for that matter)
You can try to disconnect the battery overnight so that it may reset the error.
Ultimatly if the error does not reset or comes back it is time to head to the dealer. That transmission is 'sealed' as in there is no dipstick to check fluid levels or top off fluids.
