Volvo V70 - Answered Questions & Fixed Issues


This is actually very simple, if a bit messy.

Put a couple of rags under the sensor, remove the connector from it. Undo the cap on the Schrader valve. It's on the fuel rail on the opposite side of the FPR. Press the center with a rag over it and let it soak up the gas that comes out.

Then go back to the FPR and undo the T25 screw from it, then with gently pull it out while twisting it back and forth a little and let the rags soak up the mess under it.

Then stick the new one in, tighten the screw, replace the connector and turn on the ignition a couple of times to push fuel up to the rail and pressurize it, then start the car.

My sensor failed by 'hiccuping' once in a while. It would spike the pressure to 120 psi, then drop to 20 psi, then normalize at 43 psi again, all within a few seconds.

The passenger seat has a occupant weight sensor in it. If she placed her purse or anything in it, the warning will come on. Either fasten that belt or remove any objects you have in the seat. This was my very first thought when I read your question.

This could be your IAC valve, or idle air valve which is supposed to open fully when the car is put into drive. If not, engine will stall out. Clean throttle body, as well as the IAC valve with carb cleaner. Turn IAC upside down so carb cleaner does not enter the body of the valve or motor end of business.

Unfortunately there is not an easy answer for this. Volvo remotes are difficult to program and most mechanics and / or locksmiths won't touch them.

My company does sell these remotes, but like I said above, it is difficult to find anyone to program them. If you take it to the dealer, they will want you to purchase the keyless entry remote from them, and of course charge you a huge fee!

If you can find a locksmith or mechanic in your area to program a keyless entry remote for your Volvo I would suggest purchasing the remote online and save some cash. https://www.keylessentryremotefob.com/Volvo-Key-Fob-Remote-Replacements-s/1855.htm

The light is an engine malfunction light and is registered by the vehicle's ECM (engine control module), the vehicle's onboard computer. The computer is set to read variables from the car's many sensors. If a sensor gives a reading that is out of spec, it lights the light. Under the dashboard by the driver's knee is a socket that is called an OBD11 (onboard diagnostics version 2) port. When a OBD11 code reader is connected to it, it gives a P Code and this tells what is wrong. Garages will normally read the code for free in the hope of getting the work. Connecting and reading literally takes less than two minutes. I have a reader called FIXD which relays information to my iPhone.

Hi rodknob,

What are side lights ? are they a parking light ?
Think you need to wire the side light switch feed wire to a relay and have the relay power on when the car has Accessory Power from the key Switch accessory wire.

Using a delay relay means the lights can stay on for up to 660 seconds after you turn off the car accessory key switch.
Did a car with a normal relay off accessory wire as I use to forget the headlights and flatten battery.

Or you might be able to use

but you would need to ask them how to wire it to the headlight switch and if it turns on the headlights in the dark or inclement weather.
Like my
You might need to use a relay to feed the power to the headlight switch depends on current involved .
Holden commodore cruise does this as a standard feature via an auto headlight setting on the headlight switch..

That's a light I never like. But it could be a simple fix. Tighten the gas cap. If the car senses something isn't right in that area on comes the emissions light. It can take a couple of trips back and forth to work or the store after you tighten it before the light turns off. Please don't over tighten it. There should be instructions on the cap or in that area, such as 'tighten until it clicks' or such.


If it's the original gas cap, consider replacing it. You should be able to get one at the auto parts store. Just make sure the cap is designed to fit your car. If it doesn't fit correctly your car will still sense something is wrong and that light will stay on.

I believe you just shift it to "D" and then straddle the shifter and pull it straight up with all your might. It's a bear, but doable.

Check that you have enough coolant in the radiator overflow jar! If it's too low, you get weird "intermittent" heating.
