DTC detection condition

P0746

PC SOLENOID A (Pressure Control Solenoid A Performance/ Stuck Off)

The detecting condition A or detection condition B is detected twice or more (1 second or more later after detection of the first) in the same DC under the following diagnosis conditions:

Diagnosis conditions

Engine speed: More than 600 rpm
Primary pulley speed: More than 450 rpm
Idle is not being detected.
Acceleration/deceleration speed: −0.49 m/s2 (−0.05 G) or more
The primary pulley speed experienced 300 rpm or more and the secondary pulley speed experienced 250 rpm or more at least once.
Secondary pulley speed: More than 150 rpm
TCM power supply voltage: More than 11 V

Detection condition A

Status with the shifting ratio of the primary pulley speed/secondary pulley ratio exceeding 2.981 is 0.2 sec. or more continuously.

Detection condition B

Status with the shifting ratio of the primary pulley speed/secondary pulley ratio exceeding 3.781 is 0.1 sec. or more continuously

NOTE: DC stands for "DRIVING CYCLE" and indicates a series of driving cycle of "Ignition switch OFF → ON → driving → OFF".

POSSIBLE CAUSE

Line pressure solenoid valve
Control valve assembly

FAIL-SAFE

Selector shock is large
Start is slow
Acceleration is slow
Lock-up is not performed

DTC CONFIRMATION PROCEDURE

CAUTION: Be careful of the driving speed.

1.PREPARATION BEFORE WORK

If another "DTC CONFIRMATION PROCEDURE" occurs just before, turn ignition switch OFF and wait for at least 10 seconds, then perform the next test.

>> GO TO 2.

2.CHECK DTC DETECTION
