Code No. P2719:
Abnormality in Select Pressure Solenoid Valve Function
DIAGNOSTIC FUNCTION
CVT-ECU determines that the system is defective by monitoring the select pressure solenoid
valve.
JUDGEMENT CRITERIA
- The system detects a shorter range selection period than a certain value
(N → D: 0.4 seconds, N → R: 0.3 seconds, P → R: 0.3 seconds) three times
while all of the following conditions are satisfied.
- The engine is running.
- Selector lever position: D, R
- Fluid temperature: 20° or more
- Vehicle speed: 3 km/h or less
- When all the conditions listed below are met and the forward clutch or the
reverse brake is slipping for 30 seconds while driving forward or backward.
- The engine is running.
- Selector lever position: D, R
- Vehicle speed: 3 km/h or less
PROBABLE CAUSES
- Malfunction of valve body assembly (Faulty select pressure solenoid valve)
- Malfunction of the CVT assembly

STEP 1. M.U.T.-III diagnosis code
|
|
|
Q.
Are diagnosis codes P2720 or P2721 set?
|
|
|
 Carry out the appropriate troubleshooting.
|
|
|
|
|
|
 Go to Step 2.
|
|
|
|
|
|
STEP 2. Measure the output wave pattern of the select pressure solenoid
valve at CVT-ECU connector (LBLS terminal).
|
|
|
(1)Connect the CVT assembly connector.
|
|
|
(3)When the vehicle is stationary
|
|
|
(4)Selector lever position: N
|
|
|
(5)Connect an oscilloscope, and measure the voltage between CVT-ECU connector LBLS
terminal and body earth.
OK: A wave pattern such as the one shown on  (Check
Procedure Using an Oscilloscope) should be output. There should be no noise in the output wave
pattern.
|
|
|
Q.
Is the check result normal?
|
|
|
Go to Step 3.
|
|
|
|
|
|
Refer to diagnosis code No.P2720: Malfunction of Select Pressure Solenoid Valve
(short) , or diagnosis code No.P2721: Malfunction of Select Pressure
Solenoid Valve (open) .
|
|
|
|
|
|
STEP 3. Symptom recheck after erasing diagnosis code
|
|
|
Turn the ignition switch to the "LOCK" (OFF) position, and wait for one minute. Then,
drive the vehicle for a while and check again.
|
|
|
Q.
Is the diagnosis code set?
|
|
|
Replace the CVT assembly.
|
|
|
|
|
|
Intermittent malfunction.
