2007 Toyota Yaris Question: Where is the 2007 Toyota Yaris Engine Coolant Temperature Sensor located?



Visitor, 1.5L 4 Cylinder, Boyd, TX, July 04, 2011, 08:49

Engine will not start after relacing water pump and fan belt. Water pump bearings failed which caused fan belt to tear up. Engine did get hot but I don't think it overheated. I drove about 15 miles before I realized I had a problem. I get diagnostic engine code P0117 when I use an OBD reader. No other codes in control module. The engine turns over but will not start.

    the coolant sensor read a temp that was not normal, thus the light. it does not mean the sensor is bad. a code never identifies a bad part. the motor did overheat.
    you will need to start with a compression test, fuel pressure check and spark test to find what is missing. one of them will be missing and then you can proceed with finding the problem.
    i suggest letting a shop at least diag it for you so there is no guessing.
