Circuit/System Verification

Note: Correct any engine controls and communication DTCs before diagnosing TCM DTCs.

1. DTC P0700 is an informational DTC. If there are no engine controls or communication DTCs, refer to Diagnostic Trouble Code (DTC) List -

Vehicle (See: Diagnostic Trouble Code Descriptions/Diagnostic Trouble Code (DTC) List - Vehicle) for diagnosis of TCM DTCs.

2. 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.

Diagnostic Fault Information

Typical Scan Tool Data

Circuit/System Description

Shift position switch function is installed as one part of transmission control module (TCM). The position switch consists of 2 switches, whose

values are running in the opposite direction. Automatic transmission shift range is calculated by TCM reading output voltage from gear lever

position sensor installed in TCM itself.

Conditions for Running the DTC

* Ignition voltage is 6-15.5 V.

* TCM is not in service mode.

Conditions for Setting the DTC

P0706

Sum of two position sensor voltage has deviation over 0.29 V from standard value 5 V.

P0707

Voltage on position switch 1 and position switch 2 is less than 0.127 V for 100 ms continuously after 2 consecutive times.
