I have a 1995 Subaru Legacy wagon and I think my Throttle Position Sensor my be bad. For a couple of weeks when the car would idle it would flucuate between 700 and 1500 rpms not one or other but irradically. Then once the car was warm and I would pull up to a stop sign and sometimes the rpms would drop down to 500 or just below and of course the car was running a little rough.
Now the check engine light has come on. Bummer
I first checed the idle control valve and it was working properly. I would unplug it and the rpms dropped and plugged it back in and the rpms came back up. I would like help on how to test the Throttle Position Sensor. My book tells me to test the terminals for ohms resistance depending if the throttle is closed or open. Terminals 2 and 3 throttle closed 12 k-ohms and throttle open 5 k-ohms.
Terminals 1 and 2 throttle closed 0 ohms and throttle open 1 mega-ohm. I have tried this test and my ohms results did not match. I was reading a Chiltons repair manual and do not trust it. I would like to know more ways of testing it?
Thanks!
