DTC P0746: CVT Drive Pulley Pressure Control Valve Stuck OFF2004-2005 AT-PZEV Models
NOTE: Record all freeze data and review General Troubleshooting Information before you troubleshoot.
1. Check for other DTCs or temporary DTC indicated simultaneous with DTC P0746.
Are there any other DTCs?
YES- Perform the troubleshooting for the indicated DTC. Recheck for DTC P0746 after troubleshooting.
NO- Go to step 2.
2. Clear the DTC with the HDS.
3. Warm up the engine until the engine coolant temperature reaches 176°F (80°C).
4. Check the IMA battery level gauge in the gauge assembly.
Does the battery level gauge indicate 4 - 19 segments?
YES- Go to step 5.
NO- Run the engine in the P position at 3,500 rpm until the battery level gauge shows 4 - 19 segments, then go to step 5.
5. Shift to the D position.
6. Keep pressing the brake pedal for 5 seconds.
7. Accelerate from a stop at full throttle, and drive the vehicle on a flat road at speeds 37 mph (60 km/h) or greater for more than 15 seconds. Do not release the accelerator during test-driving.
8. Slow down the vehicle and stop the wheels, and after stopping keep pressing the brake pedal for 5 seconds.
9. Check whether the HDS indicates any DTC of P0746, P0777, or P1899.
Does the HDS indicate any DTC of P0746, P0777, or P1899?
YES- CVT drive pulley pressure control valve may be stuck OFF or CVT driven pulley pressure control valve may be stuck ON:
^ DTC P0746: Replace the CVT drive pulley pressure control valve.
^ DTC P0777: Replace the CVT driven pulley pressure control valve.
^ DTC P1899: Replace the CVT drive/driven pulley pressure control valve set.
When replacing the CVT drive pulley pressure control valve and the CVT driven pulley pressure control valve. After replacing the control valve, go to step 10.
NO- Return to step 6, and repeat to test-drive. If the tester does not indicate DTC after the test-drive has been done four times, the problem was an intermittent failure; the system is OK at this time.
10. Clear the DTC with the HDS.
11. Carry out steps 4 thru 9, and check that DTC P0746 recurs.
Is DTC P0746 indicated?
YES- Replace the transmission assembly.
NO- The problem has been corrected.
