P1899

DTC P1899: CVT Drive Pulley Pressure Control Valve Stuck OFF or CVT Driven Pulley Pressure Control Valve Stuck ON

NOTE:
^ Before you troubleshoot, record all freeze data and any on-board snapshot, and review General Troubleshooting Information.
^ Keep replacement solenoid valves on hand: CVT drive pulley pressure control valve and CVT driven pulley pressure control valve set.

1. Check whether the HDS indicates any other DTC simultaneously with DTC P1899.
Are there any other DTCs?
YES - Troubleshoot the indicated DTC, and recheck for DTC P1899 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 control module (speed).
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, and keep pressing the brake pedal for 5 seconds. Accelerate from a stop until the vehicle speed reaches 40-50 mph (65 80 km/h), and run the vehicle on a flat road for more than 15 seconds. Do not release the accelerator during test-driving. Slow down to a stop, and after stopping keep pressing the brake pedal for 5 seconds.
6. Turn the ignition switch OFF. Restart the engine, and repeat test-driving step 5.
7. Check whether the HDS indicates DTC P0746, P0777, or P1899.
Does the HDS indicate DTC 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 is indicated, replace the CVT drive pulley pressure control valve.
^ DTC P0777 is indicated, replace the CVT driven pulley pressure control valve.
^ DTC P1899 is indicated, replace the CVT drive pulley pressure control valve and CVT driven pulley pressure control valve as a set.
If any part was replaced, go to step 8.
NO - Return to step 5, and repeat test-driving. If the HDS does not indicate a DTC after the test-drive has been done four times, the problem was an intermittent failure; the system is OK at this time.

8. Clear the DTC with the HDS.
9. Start the engine.
10. Shift to the D position, and keep pressing the brake pedal for 5 seconds. Accelerate from a stop until the vehicle speed reaches 40 - 50 mph (65 - 80 km/h), and run the vehicle on a flat road for more than 15 seconds. Do not release the accelerator during test-driving. Slow down to a stop, and after stopping keep pressing the brake pedal for 5 seconds.
11. Turn the ignition switch OFF. Restart the engine, and repeat test-driving step 10.
12. Check that DTC P1899 recurs.
Is DTC P1899 indicated?
YES - Replace the transmission.
NO - Troubleshooting is complete.
