AboutTed Ritter Expertise I have more than 26 years experience as toyota technician, I will be able to answer most questions related to the toyota product line up to the present year models, I specialize in difficult to diagnose problems but when posting a question please keep in mind that some situations require the used of special test equipment and diagnostic procedures especially as the newer models become more technologically advanced, so without actually having the car on hand I may only be able to try to steer you in the right direction and in some cases may have to refer you to the toyota dealer but at least you will know what you may be dealing with. Please don't hesitate to ask any questions, I will have an answer for you in most cases. When posting a question keep in mind that I reside in the US, although I get questions from all over the world I may not have an answer for models that are not sold in the US, I will do a reasonable search to try to match your model to the US model,please refrain from asking about diesel powered vehicles, I have no information for them. In most cases I will not answer questions about major modifications of OEM components, engine swapping or aftermarket products,please post a question not a statement, please provide enough basic information such as year, model, what engine and if anything has already been done to fix the problem, the more information I get the more I can help without having to ask you more questions.

Question I have a 1999 Toyota Celica with the check engine light on, after scanning it, the code P0773 Shift Solenoid E electrical? I checked the solenoids inside the oil pan and the resistance is at 13.9 Ohms and they open and close when energized with 12v I checked the resistance at the ECM from the SL terminal to ground and got 4OHMs
Answer The shift solenoid "E" is the solenoid that locks the torque converter at cruising speeds, in most cases solenoids are not the problem, they get clogged with foreign material and stop passing fluid or get stuck, I would recommend removing the transmission oil pan and inspect it for any metal particles in the bottom of the pan and if there are, the transmission is the problem and it will need to be replaced.
