    DTC Detection Condition 2

  1. The oil pressure sensor output value is 0.4 MPa (4.1 kgf/cm2, 58 psi) or more and the target gear ratio is 2.0 or more.

  2. The actual gear ratio is less than 0.5.

  4. 1-trip detection logic

 Continuously variable transaxle assembly (Shift solenoid valve SLP) Comes on DTC stored

SAE Code:

P2820

MONITOR DESCRIPTION

The ECM compares the actual gear ratio with the target gear ratio. When the actual gear ratio and target gear ratio are different, the ECM detects the malfunction, illuminates the MIL and stores this DTC.
