211 Posted October 23, 2007 Share Posted October 23, 2007 So originally I had a CEL it was a code P1133- original thread: http://www.ultimatesubaru.org/forum/showthread.php?t=80887 Well I read a little bit on this sensor and found that it could be an intermittent connection issue in the harness. So I decided to clear the code (OBDII code reader from Schucks). The reader said all codes were sucessfully cleared so took the key out and returned the reader. When I got into my car to leave the CEL was still on and the car almost died on me while pulling out of the parking lot !!! I literally had to throttle the gas to keep the RPMs up enough to get out into traffic. Within a few blocks the idle issue subsided but now the car seems to run a little different. It seems there's slightly less power under accelleration, It doesn't sound any different just feels like I have the E brake on or I'm dragging an anchor or something. What would the reader do to cause this hiccup!?! Link to comment Share on other sites More sharing options...
Legacy777 Posted October 23, 2007 Share Posted October 23, 2007 Did the reader also clear the ECU memory? Did you recheck the ECU, and was the same code still there? It's possible the ECU was reset, and when it was reset, and getting the code, it didn't run optimally until the ECU relearned the operating conditions without the sensor. I'd recommend replacing the sensor and/or checking the wiring to make sure it's good, clear the code, and see how the car runs. Link to comment Share on other sites More sharing options...

I thought the rough idle cleared up but it started up again this morning. I also disconnected the battery last night thinking that perhaps the reader could not clear the code in the first place. Now, from what I understand, the ECU is compensating and adjusting perameters to function w/ a faulty o2 sensor. I ordered a sensor from 1stsubaru.com. it should arrive tomorrow. FYI I was surprised, 1stsubaru wanted $118 shipped for the sensor. Online they estimated 4-5 day shipping. I called the dealer and they quoted $149, had 3 in stock. Called 1stsubaru to cancel the order because I dind't want to wait that long but he said, "were right here in Renton, I can have it to you by tomorrow". So IOW the dealer was not that much more if shipping delays are not an option. I can wait till tomorrow to save 30-bucks however! Link to comment Share on other sites More sharing options...
