P1CBD JEEP Possible Causes
- Transmission Hydraulic System Fluid Level
- Transmission Hydraulic System Fluid Leaks
- Operator Driving Habits
- Faulty Transmission Control Module (TCM)
How do I fix code P1CBD JEEP?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Cost of diagnosing the P1CBD JEEP code
The cost of diagnosing the P1CBD JEEP code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
P1CBD JEEP Description
This diagnostic checks for an over-temperature condition of the hydraulic Electro-Pump (EP). For example, a fluid leak or excessive gear shifting (excessive frequency of gear-shifts requested by the driver) may cause this condition. The Transmission Control Module (TCM) performs an over-temperature diagnosis based on the internal pump temperature (rotor and brushes) estimated by the pump thermal model. Specific recovery actions may be activated to prevent the pump from overheating. The diagnostic monitoring is based on three levels of severity and recovery by comparing the EP estimated brush temperature to three different thresholds: Temp 1 is a dynamic threshold and it is a function of pump duty cycle. Temp 2 is a dynamic threshold and it is a function of pump duty cycle and excessive gear shifting. Temp 3 is a fixed threshold and it is equal to the maximum calculated pump temperature.
