Code No. Pressure control solenoid valve (PCSV)
system
[Comment]
If the resistance value of the pressure control solenoid valve is high, there is an open circuit
in the pressure control solenoid valve and diagnostic trouble code No. 45 is output. If the
resistance value is low, there is a short circuit in the pressure control solenoid valve and diagnostic
trouble code No. 46 is output. In addition, if diagnostic trouble code No. 45 or 46 is output
4 times, there is an open or short circuit in the pressure control solenoid valve, fail-safe code
No. 85 is output and the vehicle is locked in
measure.

[Comment]
If the resistance value of the torque converter clutch solenoid is high, there is an open circuit
in the torque converter clutch solenoid and diagnostic trouble code No. 47 is output. If the
resistance value is low, there is a short circuit in the torque converter clutch solenoid and
diagnostic trouble code No. 48 is output. In addition, if torque converter clutch solenoid
duty continues at 100% for 4 seconds or more, there is an abnormality in the torque converter
clutch control system and diagnostic trouble code No. 49 is output. If the calculated slippage
amount (the result when the input shaft speed is subtracted from the engine speed) is 5
for ten seconds when the throttle position is 1.5
1,000 in the direct-coupled non-operating range, even though the torque converter clutch
solenoid is off, the torque converter clutch is stuck on and diagnostic trouble code No. 58
is output.
