P0746 PRESSURE CONTROL SOLENOID A
P0746 PRESSURE CONTROL SOLENOID A
DTC Description
INFOID:0000000011279355
DTC DETECTION LOGIC
NOTE:
DC stands for "DRIVING CYCLE" and indicates a series of driving cycle of "Ignition switch OFF
→ ON → driv-
ing
→ 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
1. Start the engine.
2. Drive the vehicle.
3. Maintain the following conditions for 10 seconds or more.
4. Stop the vehicle.
5. Check the first trip DTC.

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/s
2
(
−0.05 G) or more
- The primary pulley speed experienced 300 rpm or more and the sec-
ondary 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 pul-
ley 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 pul-
ley ratio exceeding 3.781 is 0.1 sec. or more continuously.
