Hi, I checked solenoid, it works, there is vacuum, to diaphram, it works under vacuum pressure also, but when I measure the voltage coming to solenoid to was 1.6 v, does this mean ecu faulty then?
My car has 99000 miles.
My car has an automatic transmission.
When you got a 1.6 volt reading from the test you did, this is not a normal test done for this code. Only a proper pinpoint done by a manufacturer approved test procedure would be able to diagnose the system for you and keep you from replacing the parts that are not needed.
