P1701 TCM

P1701 TCM

Description

INFOID:0000000009949012

This malfunction is detected when power (backup) is not supplied to TCM and the learning function stops.

CAUTION:

Immediately after TCM is replaced or after control valve or transaxle assembly is replaced (after TCM
initialization is complete), self-diagnosis result of “P1701” may be displayed. In this case, erase self-
diagnosis result using CONSULT. After erasing self-diagnosis, perform reproduction procedures of
DTC P1701 and check that a malfunction is not detected.

P1705 TP SENSOR

Description

INFOID:0000000009949015

• Accelerator position sensor is installed to upper of accelerator pedal.
• Accelerator position sensor detects depressing amount of accelerator pedal.
• Accelerator position sensor converts depressing amount of accelerator pedal to voltage signal and transmits

the signal to ECM.

• TCM receives throttle opening signal fro ECM via CAN communication.
