Looks like the most important things you need to do is rectify the "PNP" (park-neutral-position) gear selector switch. Good thread on that linked below. You are likely stuck in 4th gear (no pickup!) because of that. The 1-1-3 fuel trim code is probably going to be quite important too, indicating you're running lean.
I'm not sure how much I'd care about the ABS codes on A3. Probably a good bit of work to get all that jazz straightened out, I wouldn't know where to start except to say "ABS is disabled? GOOD!" because I loathe ABS.
If your RPM sensor had failed, the car would not start - it's critical for ignition timing. It's better called the "crank position sensor" -- most likely the problem is wiring or with the tach itself in the console.
Here's some quotes from the volvo docs that might give you some ideas ...
A1 - 313
The gear position sensor signals provide the TCM with data on which position the gear selector is in. This information is transmitted by grounding signals A, B, C and PA in various combinations. The grounding occurs inside the gear position sensor. If the TCM registers a combination of A, B, C and PA grounded signals which is not permitted, DTC 3-1-3 is set.
The TCM "Limp-home" program has been initiated and the transmission operates only in 4th gear with the position D selected in the gear selector
Possible source
Short circuit to supply or ground in the signal wiring.
Break in signal wiring
Gear position sensor incorrectly adjusted
Malfunction in gear position sensor
Contact resistance in connections.
Fault symptom
Poor performance due to the transmission operating in 4th gear.

A2 - 113
The short term fuel trim value is a measure of the manner in which the injection period included in the basic MFI module program must be varied to ensure that the engine is supplied with the optimum air/fuel mixture. This optimum mixture corresponds to a value of λ = 1. If the engine is running lean, the short term fuel trim will extend the injection period to restore the optimum mixture. A DTC will be recorded if the engine runs so lean that the short term fuel trim reaches its upper limit and remains there for 166 seconds.
Possible source
HO2S signal lead short-circuited to ground.
HO2S faulty.
Contact resistance and oxidation in MAF sensor connector.
MAF sensor faulty.
I'd also add that low fuel pressure can be responsible for too-lean codes -- including issues in the fuel tank (the pump and/or pickup hose) or the fuel filter -- As well as the pressure regulator. I'd start with the fuel filter if you haven't done it in quite a while, and verify fuel pressure. O2 sensors last 160,000km (100,000miles) or so. MAF sensor issues are usually accompanied by rough running that gets better when the sensor cable is disconnected. There's a lot of posts on these topics. I'd go over the fuel system component by component before spending a lot of $$ on parts -- the O2 sensors and MAF are around $100 USD each, not cheap.
A3 - 211 [LH Front wheel]
213 [LH Rear wheel]
214 [RH Rear wheel]
DTC 2-1-X.
If the control module finds there is no wheel sensor signal on moving off from speeds under 6 km/h (4 mph), or if the slowest wheel is turning at a speed less than 60 % of the fastest wheel, but still finds that the circuit is unbroken, it posts DTC 2-1-1, 2-1-2, 2-1-3 or 2-1-4, depending on which wheel sensor is involved.
Loose contacts in leads/joints.
Lead insulation damaged.
Contact resistance in connectors.
Ground and signal leads are too near a source of interference.
Wheel sensor loose.
Wheel sensor faulty.
Pulse wheel faulty.
Some wheel was locked while driving.
Play in wheel bearings or axle vibration.
Hydraulic unit faulty.

1-4-1
If control unit finds that pedal sensor circuit:
- is shorted to ground or supply.
- has an open circuit in the circuit.
- is giving a faulty signal.
it posts DTC 1-4-1
Possible source
- Signal lead shorted to ground or supply
- Open circuit in ground or signal lead
- Ground and signal lead shorted to one another
- Faulty pedal sensor
- Contact resistance in terminals
1-4-2
If the control module finds that the signal from the brake light switch is missing if pedal sensor leaves position 2, it posts DTC 1-4-2.
Possible source
- Signal lead short circuited to ground.
- Open circuit in signal lead.
- Faulty brake light switch.
- Brake light switch adjustment changed.
- Contact resistance in terminals.
