P0715 - Input/Turbine Speed Sensor

[furinji.saiga]

Well I was honestly surprised myself at that... Two people checked it. The first one replaced the sensor and obtained the same fault. The second one merely had a look and said it's alright. I insisted that they should check more in depth, but to no avail.

However, there was one thing that I observed :

The wiring has already been done two times. First time, there were other trouble codes, the P0715 code was not there, no check engine light, however the gear was stuck only in first and second, no matter how much i accelerate the car.

On second time the wiring was done, the gear would change now, but with a noticeable shake with every gear shift or when i slightly push the acceleration pedal at high speeds. And the P0715 error came in, and check engine lights up.

Does this help ?

In that case it definitely could be wiring related. The problem now is finding someone to check the wiring properly.

Hello Scott,

Thank you for the previous confirmation. In the end, the trouble code happened due to the wrong wiring. I had a third electrician look into the matter. He redid the wiring and the trouble code went away. The P0715 code is gone now :)

However... the shaking during gear shifts did not go away...

The electrician hinted that the following are possible :
(i) the Primary and Secondary speed sensors not working as they should,
(ii) the catalytic converter has been incorrectly removed,
(iii) the resonator could be having issues.

Do you have an idea on what could be causing the shaking ?

Shaking during shifting would indicate more an issue with the transmission then something with the exhaust setup.
