Nissan Repair: Automatic gearbox

Question
How do I test for a fault speed sensors on a Nissan serena C24 model

Answer
Hi Oscar -

There is no actual test on the speed sensor. It is dependent upon the OBD system to trigger the check engine light if it is defective.

Is your check engine light on? If so, have you replaced the VSS if it was indicated?

If not, how was the faulty VSS determined?
