hi all, being a paranoid new owner, i thought i would do a diagnostic test. the car (95 wagon euro spec) was running fine and the cel was not on but i thought i would check anyway. i got two codes- 11 which is the crank pos sensor and 32 which is the a/f system. what should i be looking for when i get this code(32)? cheers for any help

If everything appears to be running ok, (i.e. A consistent & steady hot / cold idle speed, coupled with a smooth & jerk free acceleration when on boost) then I wouldn't start worrying just yet about the codes that are logged in your ecu as they could have been introduced by the previous owner disconnecting a sensor whilst the ign was on

I personally would have a look here: (http://www.scoobypedia.co.uk/index.p.../ECUReset#toc3) and follow the instructions on how to clear the fault codes that are stored in your ecu...You can then start with a clean sheet as such & see if any codes re-appear in the coming weeks.

thanks for the reply, i did a reset and then went for a drive (15 miles) pretty steady, a couple short blasts and checked for codes and got the ok, flash on/off reading. will check again in a couple of days. if i get the 32 again i have found out it might be the o2 sensor, is there anything else that would give this code?

If code 32 is the only fault logged by the ecu then it is unlikely to have been triggered by anything other than the o2 sensor circuit...

Things can get a little tricky though if multiple codes are logged.. A failure of one component can lead to the incorrect logging of several codes.

For example, a failure of the airflow meter would have several effects on the way the engine runs, one of these would be to upset the idle speed, making it rough & erratic. This would make it impossible for the idle speed motor to produce a consistent idle. The ecu in this case would log a fault with both the airflow meter & the idle speed motor when only one fault is present.

After resetting the ecu i went out for a drive, about 10 miles, checked the codes and got the ok flashing. Have now done about 200 miles since and on checking the ecu today i have code 32 again. I am new to the impreza but the car seems to drive ok. What would be the symptoms of a code 32? can i check the o2 sensor or is it a case of straight replacement?
Where i live there are no other scooby owners nevermind specialists! so all input is really helpfull. Has anyone found a "this is how an impreza engine works" guide ? or am i going to be stuck searching scoobynet forever more?lol
cheers all

i posted a reply ref 02sensors the bosch ls02 multi fit sensor with wiring to make it fit a scoob is available for 47.15 inc vat from http://www.hglmotors.com
they also do the one with correct plugs for a scoob of various models but price goes up accordingly
