Code P1898 Description

The Continuously Variable Transmission (CVT) drive pulley pressure control solenoid valve and the CVT driven pulley pressure control solenoid valve control hydraulic pressure. The CVT drive pulley pressure control solenoid valve and the CVT driven pulley pressure control solenoid valve is controlled by duty cycle output. The spool in the CVT drive pulley pressure control solenoid valve and the CVT driven pulley pressure control solenoid valve move the valve according to the current and produces hydraulic pressure in proportion to the current. The powertrain control module (PCM) measures the current that passes through the CVT drive pulley pressure control solenoid valve and the CVT driven pulley pressure control solenoid valve and uses feedback control to compensate for the difference between the measured current and the commanded one. To shift the transmission properly, the PCM outputs a drive/driven pulley oil pressure control signal. If the pulley ratio is out of the specified range from the vehicle stopped with the forward clutch engaged to the vehicle running, the PCM detects a CVT drive pulley pressure control solenoid valve stuck ON failure or a CVT driven pulley pressure control solenoid valve stuck OFF and stores a Diagnostic Trouble Code (DTC).
