Location of Crankshaft Position Sensor

Girlfriend's 2007 3 door hatchback Yaris with the 1.5litre 1NZ-FE recently lit up the Check Engine Light and engine was running quite roughly.

Scanner revealed a P0335 error code for the crankshaft position sensor. I reset/erased the code a few days ago and so far it has not reappeared. Engine is running quite smoothly again. I have ordered a replacement sensor from eBay.

I did check an online manual for the engine control system and the engine diagram showed the position of the crankshaft position {CPK} sensor being near the throttle body.

I have had a good search but have not been able to locate this sensor, so far. At this stage, I am guessing that it is hidden away under the starter motor.

Does anyone know the precise location of this sensor?

Last night I kept looking at another section of an online workshop manual and that engine diagram was indicating that the sensor was near the crankshaft pulley. Then looked at some pictures posted by eBay sellers for the 1NZ-FE engine.

I had previously looked at this YouTube video and discounted it. Now confirmed that it does correctly show the location for the Yaris crankshaft sensor as being at the rear of the crankshaft pulley and bolts into the timing belt cover.

Retaining bolt is 10mm. I put the Yaris onto car ramps and removal of the sensor was quite easy. As per usual, hardest part was removing the electrical connector.

Hope this helps anyone else that needs or is considering replacing this crankshaft position sensor.
