Where is the ETS sensor located on this vehicle? The ETS "Check Engine" light came on 3 days ago and the gears seem to shift hard and change from 1st to 2nd to 3rd and so on. It is an automatic transmission, the fluid is clean and I have never had any problems with the transmission. Is it possible that the ETS sensor would cause this hard shifting?
ETS is the the traction control system for the car. It is not a sensor, but an entire system. You will want to have this properly diagnosed by a qualified technician, as just throwing parts at this problem will get very expensive, very quickly.
The transmission shifting may or may not be related to the ETS as both systems work together. I'll the technician know about the shifting concern as well when you drop it off for diagnostics.
