This is a strange code that doesn't appear to have one definitive reason, it's a bit of "you have a bit of a problem, but we aren't sure". Just Answer dot com mechanic says it is the MAF Sensor.

Feb 12, 2022 - On newer vehicles, the P1004 is for the short runner valve which is internal to the intake manifold and makes sure there is even air ...

Go into the back of the car to the tailgate. You will have to pull the inside cover off and inspect the rods that control the latches and the latch itself. Also lubricate everything with Slick 50 One Lube and reassemble after testing.
I had the same problem. Pressing the fuel door unlock button did not work, and I couldn't find any emergency release in the cargo/trunk area. Eventually, I clicked the Lock / Unlock button on the key fob a couple of times and tried again, this time holding the fuel door release button for 1-2 seconds, and it worked. I then sprayed some door lock lubricant into the fuel door lock in case there was something sticking in the mechanism. Don't know if this truly "fixed" the problem, but it's working now.
Yes, it's the 'pnp' switch (also known as the inhibitor switch) which is on the side of the transmission.
I own 2 Volvo 960s (3 litre automatics) which are similar in many respects ... and have that flashing arrow. It's a well known fault and you don't have much to worry about.
Rather than write it all here, you can read what I wrote as an ebay guide about it at http://reviews.ebay.co.uk/Volvo-960-Automatic_W0QQugidZ10000000003233806
I did put similar info on my website at http://www.glennsmart.btinternet.co.uk/volvo960.html with photos
Though the ebay guide is better ...
If you haven't got time to read it ... forget the flashing arrow and put a bit of black tape over it ... My wife's car has (192,000 miles) had that arrow flashing for 3 years. My car (100,000 miles) has had that flashing arrow since I bought it 1 year ago.
I did change the pnp on both cars ... but you also need to have the computer error reset by Volvo to have the light extinguished. Don't worry ... keep driving.
He may have activated the alarm system which will cause a no start condition. Cycle the key in the door to lock and unlock several times. That should correct it. If he shorted something I would start checking fuses. Start with the fuel pump fuse then check them ALL if it still has an issue.
Have you tried using the key at the tail gate, ,open with the key then move then push the locking mechanism open with a screwdriver the latch close while the door/gate was open, push it back open use some force. Hope this help if is a mechanical issue and not electrical it doesn't matter .
Your computer has detected an error with the the MAF (mass Air Flow) sensor. In conjunction with the inlet air temperature (IAT) sensor the combination is often referred to as the Air Mass Meter. Are you experiencing a 'surge and slow' effect on engine speed at idle, maybe the idle is erratic and almost stalls at times? The MAF is found as part of the air ducting just after the air filter box. There is an electrical connection to the top of it. Disconnect and dismantle the duct assembly to free the MAF unit. The MAF is a heated foil that sits in the air stream. As intake air flows over the foil it has the the effect of cooling. The cooling achieved plus the measurement of the actual temperature of the air doing the cooling by the IAT gives enough information to the engine electronic control unit (ECU) to estimate the volume of air entering and to allow the ECU to set an appropriate injection cycle to provide the correct fuel air mix. Spray the MAS with electrical cleaner, this is non residue cleaner so do not use anything harsh like carb choke cleaner or oily like WD40. Try to make no physical contact with the foil. (the IAT is bead thermistor sat in the middle of wire near the MAS foil). Once everything has air dried reassemble and reconnect. If the fault has been fixed the error code will be removed after a few restarts.
there should be a slot you can put a flat head screwdriver in to turn the motor round and close the roof. the motor assembly there is a magnet inside and a reader to tell the motor when to stop or move. the sensor can fail and ope till it cannot move any more it also as a water trigger. this in the event that the vehicle is under water the sunroof opens so you can get out. this feature can go wrong a well.
PROBLEM WAS FLASHER SWITCH WHICH HOUSES RELAY FOR TURN SIGNALS AND FLASHER UNIT--IT IS SOLID STATE AND WORKS WHEN YOU TAP ON IT--ORDERED ONE--IT SOUNDED LIKE A DIFFERENT RELAY BECAUSE SWITCH IS ABOUT 6 INCHES LONG AND EXTENDS BEHIND RADIO/CD/TAPE PLAYER--WHICH IS EASILY REMOVED (PUSH ON 2 SIDE TABS AND THEY POP OUT-GRAB THEM AND PULL ASSEMBLY OUT--PUSH RELAY OUT FROM BEHIND TOWARDS YOU--UNHOOK AND REPLACE--A 5 MIN REPAIR
GOOD LUCK

yes. the light indicates a fault in the abs system (it will store a code which can be retrieved with a code reader), and the abs system will be disabled until repaired. your brakes will function normally, but you will have no abs feature.
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.
The tracs off light comes on automatically whenever the ABS light goes off. Each of 4 wheels has an ABS sensor. The ABS light usually comes when any one of these sensors go bad. It could also be the ABS computer but the computers usually last the lifetime of the car on Volvos. Then, of course it could be some wire spliced somewhere in the ABS circuit and that would be something very difficult to find where the short is. But try the sensors, they are usually the culprit.
