Hi:
I am pretty sure that fault code P0698 is for your throttle position sensor, or accelerator position sensor. Often, as this fails, you can clear the code, and it will come back on during throttle movement.

Had a similar problem on fiesta and think the fault your describing is due to the egr valve, what seems to happen is egr valve goes short circuit internally and this drops reference voltage down. Other sensors which are supplied by this reference voltage fail to work and cause the vehicle to stall.

I have a 2005 forester XT (south Africa). The car has a jerkyness at constant speed and when pressing the gas pedal, you can feel the constant jerks. Had a diagnostic check done at subaru, but no fault...


At 213K km, there's wear in the valve guides (== more oil consumption), the O2 sensor(s) are getting tired, and the plug wires and plugs are old. All these can cause the jerkiness.

Changing the plug wires would be a good start, followed by the plugs, unless thus has been done. A tired O2 sensor usually sets the occasional 420 error code.

You could also try resetting the ECU. What this does is place it into a learning mode, and the jerkiness may disappear for a while. If it does, it means the ECU is running the engine around the edge conditions. Replacing the O2 sensor may help, but don't do it unless you get an error code.

Also, check for exhaust leaks on the "donut" connection after the catalytic converter. Even a small leak can cause the O2 sensor to report "off" conditions.

My 1999 s type v6 auto keeps pulling when doing around 30 - 50mph, what could be the problem


Unfortunately a lot of things could cause this eg - speed sensor - accelerator sensor - throttle body - bad connections in wiring loom. Best bet = get car on diagnostic rig and see what fault codes are stored or get a running test done whilst car in action. Good luck - hope this helps

If you can check actual values whilst engine is idling, air mass should be around 18kg. The symptoms you mention indicate a maf sensor is at fault, these are prone to failing and can cost around £300 from porsche

This code is not documented so the code reader is giving a false reading.
If the car runs OK and check engine light is not on, I would forget about it.
