Conditions for Clearing the DTC



P0716 and P0717 are Type A DTCs.



Diagnostic Aids



Inspect the ISS/OSS, harness, connector, and control solenoid valve assembly for metallic debris and the 1-2-3-4 and 3-5-R clutch housing splines



on the outside diameter surface for damage or misalignment. Proper torque of the ISS/OSS mounting bolt is critical to proper speed signal



operation.

Special Tools



DT-47825-10 - Jumper Harness



For equivalent regional tools, refer to Special Tools (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Tools and Equipment).



Circuit/System Verification



1. Ignition ON, verify with a scan tool the transmission ISS/OSS supply voltage test status parameter displays OK.



2. Engine idling in Park, observe the Transmission ISS parameter on the scan tool while varying the engine speed. The Transmission ISS



parameter should vary with the engine speed and not drop out.



3. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the



conditions that you observed from the Freeze Frame/Failure Records data.



Circuit/System Testing



Note: You must perform the Circuit/System Verification first.



1. Ignition OFF, remove the Q8 control solenoid valve assembly. Refer to Control Solenoid Valve and Transmission Control Module Assembly



Replacement (See: Powertrain Management/Transmission Control Systems/Actuators and Solenoids - Transmission and



Drivetrain/Actuators and Solenoids - A/T/Shift Solenoid/Service and Repair).



2. Connect the DT-47825-10 - jumper harness between the vehicle wire harness electrical connector, and the Q8 control solenoid valve



assembly electrical connector.



3. Ignition ON, test for 8.3-9.3 volts between the ISS/OSS voltage circuit terminal B on the Q8 control solenoid valve assembly and ground at



the transmission case.



瀚慖f not within the specified range, replace the control solenoid valve assembly.



4. Perform the Control Solenoid Valve and Transmission Control Module Assembly Input Shaft Speed/Output Shaft Speed Input Test (See:



Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing and Inspection/Component Tests and General Diagnostics/Control



Solenoid Valve and Transmission Control Module Assembly Input Shaft Speed/Output Shaft Speed Input Test).
