Есть ли коды неисправности датчика детонации, он не сообщил. Но ему уже посоветовали:Technician Phyllis Hendersоn писал(а):...After driving few milеs less than 4milеs will not shift into od and no tcc.
Found information of knock sensor problem and will set a knock sensor code, however ecm still commands 4th gear also checked for voltage on circuit and it has voltage on S4 sol.
Connected a Dvom meter on the S4 circuit, and it continues to show voltage on the circuit after 3rd gear shift and continues to show voltage but no shift. I would assume if the problem of knock sensor I would not see voltage on the circuit showing computer is not commanding 4th. Changed sl4 solenoid No change.

Посмотрим чем там закончится ...Williаm from Tennessеe писал(а):Richard is correct knock sensor will inhibit 4th,tcc. I had same car you have doing same thing. Replaced knock sensor took care of problem.
