I just finished putting a 2005 toyota celica motor in a 2002 celica (both 1ZZE type engines). There was a sensor that was located under the center of the intake manifold that was different on the '05 (2 wires) from the '02 (1 wire), so I put the sensor from the '02 in the '05 engine. I am now getting a check engine code saying there is an engine coolant tempertaure sensor malfunction. The gauge slowly goes up about 1/2 way and then all of a sudden (less than a second) it maxes out and the check engine light comes on. The engine does not overheat. Can you tell me where the engine coolant temp. Sensor is on an '05 celica engine? Could there be some air pockets still in the engine that hit the sensor and cause the malfunction?
