I had a "Check Hybrid System" Warning one evening after a short drive. Scan produced P0A3F - Drive Motor A position sensor circuit.
Never heard of it before. So, I examine the transaxle and there's a sensor, almost identical to the camshaft position sensor on the valve cover.
I pull it out, nothing unusual there, and plug it back, clear the error, vehicle starts & runs normal. Error gone.
Next day, engine goes off on the highway. Same warning, same DTC. I manage to pull over on E-mode & repeat the same trick, doesn't clear the error this time. On closer examination, I notice the second sensor that you can get to when you remove the FL wheel.
So, I unplug & re-plug it. Error clears. Hasn't returned for two months now.
Naturally. I'm worried that the sensors may fail and I search toyota parts stores online for a replacement. Didn't find any part numbers for "motor position sensors". They're not even listed as parts related to the transaxle.
Has anyone replaced these things? Or had any reason to?

hello I am having the same, were you able to order the part and fix it? If soon could you email me [email protected]

The error has not returned since. I haven't had any luck with ordering spare sensors. Toyota probably doesn't think they are prone to failure. They are not listed as part of the transaxle parts on major parts dealers websites.

is it easy to locate the sensor? Do you have a picture or video where it’s at? I have a 2006 model

If your vehicle is a camry hybrid, one sensor is accessible if u remove the intake air filter housing. The other, when u take off the driver's side front tire.

I have a P0A40 OBD code from my 2006 Toyota Highlander Hybrid ( Drive motor position sensor). I would like to know the location of the sensor so I can replace it. Thanks
