Code No. P084A: Abnormality in Fluid Pressure Sensor Function
 
 
 
 
DIAGNOSTIC FUNCTION
The CVT-ECU determines that the system is defective when the primary pressure sensor output voltage is outside the predetermined value range.
 
 
JUDGEMENT CRITERIA
All the conditions listed below remain for 5 seconds.
  • The pulley ratio is 0.5 or more, 1.0 or less.
  • The primary pulley speed is 300 r/min or more.
  • The secondary pulley speed is 250 r/min or more.
  • Target shifting speed is 0.1/sec or less.
  • The primary pressure is outside the predetermined pressure range.
 
 
PROBABLE CAUSES
  • Malfunction of valve body assembly (Faulty primary pressure sensor, secondary pressure sensor)
  • Damaged wiring harness and connectors
  • Malfunction of the CVT assembly
 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE diagnosis code
Are diagnosis codes P0842, P0843, P0847 or P0848 set?
Carry out the appropriate troubleshooting.
Go to Step 2.
 
STEP 2. 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.
Is the diagnosis code set?
Replace the CVT assembly.
Intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ).
