Suzanne Posted January 25, 2009 Share Posted January 25, 2009 Check engine message comes on, stays around for awhile, then goes off. Reading I got was PO115. Anyone experience the same and can you tell me what you did to correct the problem? Thanks Quote Link to comment Share on other sites More sharing options...
Cougar Posted January 25, 2009 Share Posted January 25, 2009 (edited) Welcome to the forum here. The trouble code you have is a Engine Coolant Temperature Circuit code. This means the coolant sensor for the ECU has a problem in the circuit between the ECU and the sensor. It is pretty common for the connections at the sensor itself to get gummed up so I recommend you check that first in the hunt for the trouble. In case you aren't aware of it, that sensor is not the same as the one for the dash gauge. The CTS sensor you want to check has two leads going to it so look for that. I think it is located on near the top-front of the engine on the passenger side but I'm not sure of that.

njdrsubaru Posted January 25, 2009 Share Posted January 25, 2009 :grin: i just changed mine today its right under the aic valve... under the passenger side intake manifold... with a brown plug, screwed into the coolant return pipe... tip: heat the car up to normal running temp, then let it cool down enough so u can touch that way u have a warm engine and the hoses u need to removed will come off easily Quote Link to comment Share on other sites More sharing options...
Suzanne Posted January 29, 2009 Author Share Posted January 29, 2009 Thanks for the responses from you both. Not sure how to reply to the two of you independently, on this site yet. I did know what the code pertained to, but that's about all. Somewhere, I saw where it said to repl. the throttle under the pass. side and reset the MIL light. Since I'm no expert, that wasn't too helpful. So you're saying these connections get gummed up. Meaning.. I need to clean? the connections and make sure they are plugged in tight? As one of you just changed his, what exactly did you change? Do I need a new hose or a part of some kind, that's part of a hose? You meant to type, under the a/c valve correct?

Cougar Posted January 30, 2009 Share Posted January 30, 2009 So you're saying these connections get gummed up. Meaning.. I need to clean? the connections and make sure they are plugged in tight? My e-mail address is suzi441@earthlink.net The code has nothing to do with the throttle sensor. You need to clean and check the connections to the CTS sensor. The location of the sensor was given in an earlier post, number 3. Quote Link to comment Share on other sites More sharing options...
