DI-1053
DIAGNOSTICS - AUTOMATIC TRANSMISSION (A750E for 1GR-FE)
DIDVK-01
DTC P0781 1-2 Shift (1-2 Shift Valve)
Valve Body: 1-2 Shift Valve SYSTEM DESCRIPTION
The 1-2 shift valve performs shifting to 1st gear and other
gears.
D14169
DTC No. DTC Detection Condition Trouble Area
The gear required by the ECM does not match the actual gear S Valve body is blocked up or stuck (1-2 shift valve)
P0781
when driving (2-trip detection logic) S Automatic transmission (clutch, brake or gear, etc.)
MONITOR DESCRIPTION
This DTC indicates that the 1-2 shift valve in the valve body is locked in the direction the spring compresses.
The ECM commands gear shifts by turning the shift solenoid valves "ON/OFF" and switching oil pressure
to the valves in the valve body.
The ECM calculates the "actual" transmission gear by comparing the signals from the input speed sensor
(NCO) and the output speed sensor (SP2). The ECM can detect many mechanical problems in the shift sole-
noids, valve body, and the transmission clutches, brakes, and gears. If the ECM detects that the actual gear
position and the commanded gear position are different, it will illuminate the MIL and store the DTC .
