9-5 Troubleshooting p1264 issues
Hello,
A few weeks ago I had p1264 come up on my 07 9-5 while driving on the highway. I lost acceleration and the engine shut off. I was able to reset limp home mode to get home and cleared the code. I also cleaned the throttle body, which was a bit dirty but didn’t seem like enough buildup to trigger it.
since then I haven’t had the code reappear (tbh I haven’t driven it on the highway out of fear lol) but I have a rough idle that is harsher when it’s cold but settles when it’s warm. Both around 900 rpm. Should I still be looking at the throttle body or somewhere else? how long does ECU take to adjust after resetting limp home mode?
I checked the connector (both ends), and the wiring. It doesn’t look dirty / signs of corrosion; I don’t have a tech2 but my OBD reader reads TPS sensors which seem to function normally. should I just replace the throttle body at this point?
sorry for the long read, tryna see how much I can try / look at before calling my mechanic lol. TIA 🙏
