bgambino Posted August 23, 2011 Share Posted August 23, 2011 okay...I have 2 things going on here (or maybe just one) 96 legacy 2.5 sedan For about a year, the temp gauge was only reading maybe 1/4 way up the scale. Infared shot of hoses shows actual temp is fine compared with my other soob. What sensor is this that is shot and how to identify it? (1 wire or 2) Too lazy to have swapped one yet Today the cel lite came on for the first time and scan tool says PO115 (temp sensor malfunction) Is this the same exact sensor or is it the other one? thanks in advance Quote Link to comment Share on other sites More sharing options...

Is this indicating the 2 wire sensor or what? Quote Link to comment Share on other sites More sharing options...
mdjdc Posted August 23, 2011 Share Posted August 23, 2011 It is telling you that the two wire sensor is bad. That one will effect the running of the car as the computer sets the fuel mixture based on the engine temp. Replace them both and be done with it. If you want a set of used ones, let me know.

Is this indicating the 2 wire sensor or what? CEL codes must be generic amongst car manufacturers. If you do a google search, and type in "PO115" there are numerous websites that discuss the meaning of that code. Try this, and you will see what I mean.
