Question about 2000 Subaru Outback

Open Question

250 rpm when clutch is engaged/idling, stalled twice

2000 Subaru Legacy Outback has shut off twice while driving (engine stopped and dashlights came on), both times with the clutch engaged to stop. Idling rpm around 250 instead of normal~750. The check engine light revealed a p0325 knock sensor error that has existed for longer than these symptoms have occurred. The car will sometimes smell of gas when warming up on cold days and just after starting rpm have reached 1500. I cleaned the battery terminals and also checked the coolant which was normal.

SOURCE: I have a1999 Subaru outback wagon, it was running

Best thing to do in your case is take it to a mechanic and put it on a computer scanner to bring up a code # to detect the faulty part. The Check Engine Light usually represents a problem in the emissions system.

Hi there,

Erratic idle is often due to a vacuum or air leak in one of the engine systems, or faulty sensors sending incorrect data to your engine's computer.

As your vehicle is OBD-II compliant (ie has OnBoard Diagnostics) your engine computer will have stored the appropriate fault codes.

Before you start changing any components, always have the codes extracted from your onboard computer as this process will quickly identify which circuit (or sensor) is causing this condition. Changing your TPS may have been unneccessary.

SOURCE: I just replaced my accessory

Sounds like changing the belt had nothing to do with the problem unless something was disconnected or damaged. Maybe you already know all the problem codes, but if not here is a list of them. Also, when you make a reapair on one of the codes you have to reset the codes. They stay in memory until you rested them. So if you reset the 336 and 341 codes my disappear. Reseting the codes doesn't have anything to do with not starting. Make sure nothing was accidentaly disconnected or damaged. The throttle sensor is on the throttle which is in the housing that the air cleaner connectes with. I'm unsure where the Knock sensor is located. The catalyst sensor is probably one of the oxygen sensors in the exhaust pipes, the farthest away from the engine. Your discription of how the care died sounds to me like the throttle sensor.
The problem you have withour having someone check all these item with a system scanner, is you don't know which is defective or if they all are. When you purchase any of these sensors, they are expensive and they are not returnable once you open the packaging. If it not a connection or broken item that is ovbious, I recommend you have a quilified shop check the problem. Guessing can cost a lot for no reason.

P0122 Throttle/Pedal Position Sensor/Switch "A" Circuit Low Input
P0325 Knock Sensor #1 - Circuit Malfunction (Bank #1 or Single Sensor)
P0336 Crankshaft Position Sensor "A" Circuit Range/Performance
P0341 Camshaft Position Sensor Circuit Range/Performance
P0420 Catalyst System Efficiency Below Threshold (Bank #1)

Good luck

Thanks for using FixYa.

High idle unless driving in gear, but if clutch is pushed in or car is in neutral rpm goes up to 2900

run fault codes to check for accelerator position sensor problems . Check for vacuum leaks. If cable accelerator then check that the return spring on the end of the cable is attached and not missing.

2000 subaru outback timing belt is changed, cranck and cam sensors changed but car stall crank and engine keep shutting off while driving

If this vehicle has a stand alone ignition module, that is more than likely the culprit. Change the igntion module and the problem should go away.

2000 Subaru Outback transmission problem

After a good deal of research and several shops suggesting a rebuild of the transmission, I decided to have the trans fluid and filters changed before doing anything. It was a tough call because it could have been a waste of $125. As soon as the spin off filter was removed you could see it was blocked. So the hydraulic pressure in the system was way down, still enough to engage reverse and enough to work all the shifts, but not enough to engage forward without a slight tap on the accelerator.

My Subaru has 240 000 km on it and I suppose the clutch pack rebuild wouldn't hurt, but as it is now it engages quickly and shifts up are noticeably smoother.

May not be the solution for every case, but it solved my situation.
