SYMPTOM
P0869-LINE PRESSURE HIGH
WHEN MONITORED
Continuously while drying in a forward gear.
SET CONDITION
The PCM continuously monitors Actual Line Pressure. If the Actual Line Pressure reading is greater than the highest Desired Line Pressure ever used in the current gear, while the Pressure Control Solenoid duty cycle is at or near its maximum value (which should result in minimum line pressure), this code will set.
POSSIBLE CAUSES
- CHECK FOR RELATED DTC'S
- 5-VOLT SUPPLY CIRCUIT OPEN
- POOR LINE PRESSURE SENSOR CONNECTION
- PRESSURE CONTROL SOLENOID CONTROL CIRCUIT OPEN
- 5-VOLT SUPPLY CIRCUIT SHORT TO GROUND
- PRESSURE CONTROL SOLENOID CONTROL CIRCUIT SHORT TO GROUND
- INTERNAL TRANSMISSION - LINE PRESSURE HIGH
- LINE PRESSURE SENSOR
- TRANSMISSION CONTROL MODULE
- INTERMITTENT WIRING AND CONNECTORS
