Advanced Diagnostics - DTC P2714: A/T Clutch Pressure Control Solenoid Valve D Stuck OFF











General Description
A/T clutch pressure control solenoid valve D is installed on the transmission housing. A/T clutch pressure control solenoid valve D is operated by the powertrain control module (PCM) and converts line pressure to A/T clutch pressure control solenoid valve D pressure. A signal from the PCM is output to A/T clutch pressure control solenoid valve D to supply proper A/T clutch pressure control solenoid valve D pressure to the correct gear clutch according to the shift schedule and the driving conditions. When the current from the PCM is high (ON), A/T clutch pressure control solenoid valve D operates and A/T clutch pressure control solenoid valve D pressure increases. When the current from the PCM is low (OFF), A/T clutch pressure control solenoid valve D turns off and A/T clutch pressure control solenoid valve D pressure decreases. The PCM monitors the input shaft (mainshaft) speed and the output shaft (countershaft) speed according to the shift status determined by the shift schedule. When an improper gear ratio is output for the shift schedule, the PCM detects an A/T clutch pressure control solenoid valve D stuck off failure and stores a DTC.

Diagnosis Details

Conditions for setting the DTC
When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the PCM memory. If the malfunction returns in the next (second) drive cycle, the MIL comes on and a Confirmed DTC and the freeze data are stored.

Conditions for clearing the DTC
The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the battery.
