Hi there:
This means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. A more technical description would be that the MAF circuit had lower than expected voltage (air flow).

A code P0102 may mean that one or more of the following has happened:

The MAF may be disconnected, or a wiring connection may be bad
The MAF may be dirty or otherwise contaminated (Note: if you use a reusable oiled air filter, be careful not to apply too much oil or that can contaminate the MAF).
The MAF sensor may be faulty
The vehicle computer may be faulty (very rare)

Possible Solutions

The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:

Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
Inspect for any air leaks near the MAF sensor.
Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor.
Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
Replace the MAF sensor.

Hope helps.

SOURCE: 2001 saab 2.3t want to make cars turbo have more boost

you can fit a manual boost tap that fits into the hose from the wastgate solinoid to the wastgate which tricks the wastgate into opening a little later raising the boost pressure, tho i recommend a electronic boost controller as it holds boost better in the higher revs. Be mindful only raise the boost by 2-3 pounds as the more boost you run the hotter the air gets and the more likley it is to start to detonate.

SOURCE: can i you drive without turbo on saab 9-5 2000

No. Turbo charged engines have been designed to have the turbo. The turbo uses exhaust gas to spin a dual air compressor to push additional air into the intake, without it the car probably won't even run. There are numerous electronics monitoring pressures and temperatures. Sorry turbo has to be fixed for car to run properly.

My saab 95 1.9 tid revs fine in neutral when put in drive and pull of there's no power won't go above 3000 ram any ideas


HI Derek.

There are a few possibilities that come to mind.
3K RPM is generally about the break-even point for when Turbo boost would kick in. There is a dump valve on the turbo system that opens up and vents the extra turbo pressure under high-rpm situations where the boost isn't needed - say high but steady speed on a freeway. If the dump valve system is malfunctioning, then that anticipated turbo run-up in power won't happen.

Revving fine when in neutral may not tell you much, other than that the engine can rev. The gating system will (or should) run differently under load - whether climbing a hill or accelerating, this is where you want the turbo boost to give you the extra power. THat's where the exhaust gate should stay shut, or mostly shut, to allow the turbo to force more air into the pistons.

You might want to check whether the APC (Automatic Performance Control) for the turbo has a separate fuse. (The name might be different on your model, I'm remembering from my 80s/90s era Saabs). If the fuse is blown, that could also lead to lame performance, especially as I'd imagine that the system would be built to fail or go to full open if the APC fails or loses power - that'd keep people from having run-away power that they can't manage.

Hoping this helps

TURBO NOT BOOSTING


Hello, I am a Saab technician from upstate new york. It sounds to me that the turbo wastegate rod may be seized to the turbo control valve. The easiest way to try to fix this is to spray penetrating oil on the turbo valve/ wastegate rod and work it back and forth with a pry bar. Many times u can also heat this up with a torch and pray. If those two things don't work than the turbo valve itself is seized into the guide hole machined into the turbo. good luck.

My 1999 saab 95 has been dying while driving the past 2 days. i can pull the P1300, P1549, P0300 codes with a obdii reader. where do i start with fixing this problem


p1300 and p0300 Inspect the wiring, DI cassette, and the spark plugs are clean and making good contact. p1549 Check the charge air system and the air flow through the Turbo boost pressure control valve. These are relative the code you received.

Your problem with the APC system. Any perceived fault and you only get base boost. The most likely fault is the boost pressure sensor located under the dash on the left-hand side. when it is bad you often hear the APC solenoid valve clicking at idle.
