SAAB 900

I bought a 1995 Saab 900 SE convertible with 109,000 miles and it has some issues.

  • has a check engine and SRS light
  • codes came back and were cleared
  • knock sensor, mass airflow sensor, p0326 p0331/2 p0102, p0113
  • the exhaust sounds loud
  • should i be worried? will this effect my emissions?

Will this effect my emissions

Code P0326, P0331 and P0332 (Knock Sensors) will not cause any engine performance problems. Code P0102 will cause engine performance issues and emission issues because of that. Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor.

Code p0113 refers to the IAT which is located in the air intake around the same area as the MAF sensor. I would check the connections and clamps to make sure there just isn’t a loose connection.

Code P0326 – Knock Sensor Circuit Performance

P0326 Probable Causes

  • Faulty Knock Sensor
  • Knock Sensor circuit poor electrical connection
  • Knock Sensor harness is open or shorted
  • Faulty Engine Control Module (ECM)

Code P0102 – Mass Air Flow Circuit low input

P0102 Probable Causes

  • Faulty mass air flow sensor
  • Intake air leaks
  • Dirty mass air flow sensor
  • Dirty mass air filter
  • Mass air flow sensor harness is open or shorted
  • Mass air flow sensor circuit poor electrical connection

Code P0113 – Intake Air Temperature Sensor Circuit High

P0113 Probable Causes

  • Faulty Intake Air Temperature (IAT) sensor
  • Dirty air filter
  • Intake Air Temperature (IAT) sensor harness is open or shorted
  • Intake Air Temperature (IAT) sensor circuit poor electrical connection

1999 SAAB 9-3

I have a manual transmission on my SAAB. The shifter was disconnected to put in a new ignition switch. But transmission was not locked in 4th gear when linkage clamp was loosed. How do I get the car back into 4th with the linkage disconnected?

Reconnect the linkage and move the shifter. Sounds vague but it is what is required.

1996 SAAB 900

Stalls as if out of fuel

My 1996 Saab 900s 2.3 will with out warning stall weather I’m driving or parked. I replaced fuel pump and filter, coil and spark plug wires, don’t know where to look next, any advice would be appreciated. Runs great when running only 133,000 on it

Fuel Pressure regulator maybe. I would start by connecting a fuel pressure gauge and taping it to the windshield. Test drive and monitor the fuel pressure when it starts to stall. Compare your readings from when it is running well vs stalling out.

2002 Saab 93while driving down the highway at 70 miles per hr. my saab just quit. what would cause this?


  1. Out of gas
  2. Alternator failure – bad alternator or belt came off
  3. Ignition Failure
  4. Timing Failure
  5. Electrical connection failure
  6. Engine sensor failure – Check Engine light illuminated

My On Star say that the battery is not charging. I have replaced the battery and alternator and the car will still not start.

Head gasket leaking coolant. Dealer did diagnostic test, put dye with result. Necessary to remove cylinder head and replace all seals and gaskets. Job to cost $3,500. Any advice? Its too pricey to bring it to the dealer but I have second thought if the diagnosis is very definitive.

I have multiple issues going on with car. The main question that I have, is: If car stalls, and won’t move, or even when it seems to be running ok, does this necessarily mean that I have tranny problems ? Some of the probable other issues that I think might be relevant. Cylinder head probably blown. Vacuum lines either hooked up wrong, or not at all. Significant coolant leaks, so not able to use a core tester.

Mechanic has it now, and I’m just concerned about being taken for a ride.

recently purchased two weeks ago, clock was flashing 12:00(note). shortly after leaving the dealer within 10 miles I stopped for a quick lunch, went out to start car and in the process goes through the check mode. this is the first time i encountered the ” stability control failure” message in the info center. I cleared the message and went on my way. Two days later this comes up on the info center and now stays. putting two and two together the dealer cleared the code by disconnecting the battery and resetting. ok, so took it to a shop to read the code and the general description is related to the YAW SENSOR. Curious how big of a project this can turn into if it is a sensor? The ABS works but the ESP now does not, but did when I test drove it. The dealer is willing to cover some of the cost for the repair to a certain point or my other option is give the car back for my trade or refund. In your professional opinion does this sound like an expensive fix? Thanks
