2007 Toyota Yaris Q&A
2007 Toyota Yaris Question: Where is the 2007 Toyota Yaris Engine Coolant Temperature Sensor located?
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. - Visitor
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.
