The cost to diagnose the P0869 JEEP code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
The Transmission Control Module (TCM) continuously monitors actual line pressure and compares it to the desired line pressure. If the difference between actual line pressure and desired line pressure is 10 psi (.7 kg/cm2 ) or greater, DTC P0867 will set. Transmission system will default to open loop line pressure control resulting in a fixed solenoid duty cycle. This duty cycle will change slightly depending on temperature and current gear.
