CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM, Diagnostic DTC:P282B

DTC Code DTC Name
P282B Pressure Control Solenoid "K" Electrical (Shift Solenoid Valve SLS)

DESCRIPTION

The ECM uses shift solenoid valve SLS to control the secondary pulley pressure and belt clamping pressure according to the input shaft torque. Additionally, shift solenoid valve SLS is used to control the forward and reverse clutch hydraulic pressure when the forward and reverse clutch is engaged.

DTC No.

    1. C199169C09

      *a

      Component without harness connected

      (Transmission Wire)

      Disconnect the transmission wire connector.

    2. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection

      Condition

      Specified Condition

      3 (SLS+) - 8 (SLS-)

      20°C (68°F)
