Typical Scan Tool Data










Circuit/System Description

The automatic transmission (AT) input and output speed sensor (ISS and OSS) assembly each are part of a single harness. The ISS is a hall-effect type sensor. The ISS/OSS mounts to the control valve upper body assembly. The ISS sensor end faces the splines on the 1-2-3-4 and 3-5-R clutch housing outside diameter surface. The sensor receives 8.3-9.3 volts on the ISS/OSS supply voltage circuit from the control solenoid valve assembly. As the 1-2-3-4 and 3-5-R clutch housing rotates, the sensor produces a signal frequency based on the splines on the clutch housing outside diameter surface. This signal is transmitted through the ISS signal circuit to the control solenoid valve assembly. The control solenoid valve assembly uses the ISS signal to determine line pressure, transmission shift patterns, torque converter clutch (TCC) slip speed and gear ratio.

* Ignition voltage is 8.6 volts or greater.
* The vehicle speed is greater than 0 km/h (0 mph).
* The throttle position must be greater than 0 percent.

P0717
* DTC P0717 is not set.
* The engine speed is 400 RPM or greater for 5 seconds.
* Ignition voltage is 8.6 volts or greater.
* The TCM must receive a valid torque signal from the ECM.
* The vehicle speed is greater than 16 km/h (10 mph).
* The engine torque is greater than 50 Nm (37 lb ft).

Conditions for Setting the DTC

P0716

The transmission input speed sensor RPM drop is greater than 900 RPM for 1 second.

P0717 - Condition 1

Transmission input shaft speed is less than 67 RPM for 5 seconds.

P0717 - Condition 2
* DTC P0722 is set.
* The transmission input speed is less than 654 RPM for 5 seconds.

Action Taken When the DTC Sets

P0716
* DTC P0716 is a Type A DTC.
* The TCM freezes transmission adaptive functions.
* The TCM turns OFF all solenoids.
* The TCM inhibits Tap Up/Down functions.
* The transmission defaults to second gear.
* The TCM enables torque management.
* The TCM inhibits manual shifting of forward gears.

P0717
* DTC P0717 is a Type A DTC.
* The high side driver is turned OFF.
* The TCM turns OFF all solenoids.
* The TCM freezes transmission adaptive functions.
* The TCM inhibits Tap Up/Down functions.
* The TCM inhibits manual shifting of forward gears.

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.

Circuit/System Verification

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

• If the parameter value displays Fault or Malfunction
Refer to Circuit/System Testing below.

• If the parameter value 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.

• If the parameter value does not vary with engine speed or drops out
Refer to Circuit/System Testing below.

• If the parameter value does vary with engine speed and does not drop out

3. After performing the above steps, verify that the DTC does not reset by operating the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data. If the vehicle passes the Circuit/System Verification procedure then STOP. Do not perform the Circuit/System Testing or Component Testing as this may result in an unnecessary part replacement. Refer to Testing for Intermittent Conditions and Poor Connections Testing for Intermittent Conditions and Poor Connections.

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 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.

• If not between 8.3-9.3 volts
Replace the control solenoid valve assembly.

• If between 8.3-9.3 volts

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

• If the Q8 control solenoid valve assembly does not pass the ISS/OSS test
Replace the Q8 control solenoid valve assembly.

• If the Q8 control solenoid valve assembly passes the ISS/OSS test

5. Inspect the machined teeth on the 1-2-3-4 and 3-5 clutch housing outer surface for damage or misalignment.

• If the machined surfaces are incorrect, damaged, or improper alignment
Repair or replace as necessary.

• If the machined surfaces and alignment checks OK

6. Replace the B14A/B14C ISS/OSS assembly.

Repair Instructions

* Perform the Reset Transmission Adapts Reset Procedure following all transmission related repairs.
* Perform the Diagnostic Repair Verification Verification Tests after completing the repair.
* Perform the Input and Output Speed Sensor Replacement Service and Repair.
* Refer to Control Module References Control Module References for control solenoid valve assembly replacement, programming, and setup.
* Perform the Control Solenoid Valve and Transmission Control Module Assembly Input Shaft Speed/Output Shaft Speed Input Test Control Solenoid Valve and Transmission Control Module Assembly Input Shaft Speed/Output Shaft Speed Input Test.
