The check engineer light is always on, and the dash indicator that indicates which mode the transmission is set for: power or economy indicates that the mode cannot be set.
As for codes, I am told by my mechanic, that the code indicates a speed sensor not working; he did not give me the actual code number.
The transmission mechanic was the one who confirmed the speed sensors are working and that the main computer is not reading the sensors' output.
In fact, the transmission mechanic showed me the output from the sensors showing that they are providing speed information and he showed me that the car's computer shows 0 for the data from the sensors.
A website I was studying mentioned the LS400 exhibiting the same characteristics as my ES300; the information there indicates that the ECM has one or more bad capacitors and once replaced the transmission problems were solved for the LS400. I was wondering if this could be a possible root cause.
I also read yesterday that someone claimed a bundle of wires in the trunk can become shorted-out due to opening and closing of the trunk; this website claims this is a known issue with the ES300. Do you know if this is a possible root cause?
