Causes and Solutions for Jeep Code P051D
| Cause | Solution |
|---|---|
| 5-VOLT SUPPLY CIRCUIT SHORTED TO VOLTAGE | Check the wiring and connectors for corrosion or damage and repair or replace as necessary. |
| CRANKCASE PRESSURE SENSOR SIGNAL CIRCUIT SHORTED TO THE 5-VOLT SUPPLY CIRCUIT | Inspect the wiring and connectors for any signs of corrosion or damage and repair or replace them as necessary. |
| SENSOR GROUND CIRCUIT OPEN/HIGH RESISTANCE | Check the wiring and connectors for corrosion or damage and repair or replace them as necessary. |
| CRANKCASE PRESSURE SENSOR | Replace the crankcase pressure sensor or clean the connections. |
| POWERTRAIN CONTROL MODULE (PCM) | Replace the powertrain control module (PCM) or reflash the module. |
Jeep Code P051D is a code that is generated when the crankcase ventilation hose is disconnected from the clean air tube, causing PCV vapors to leak into the atmosphere whenever the engine is in a boost. A faulty 5-volt supply circuit, crankcase pressure sensor signal circuit, sensor ground circuit, crankcase pressure sensor, or powertrain control module (PCM) can also be at fault for this code. It is important to know the underlying causes and solutions to diagnose and fix this code. This article will discuss the causes and solutions for Jeep Code P051D, from a 5-volt supply circuit shorted to voltage to a powertrain control module (PCM).
5-VOLT SUPPLY CIRCUIT SHORTED TO VOLTAGE
When the 5-volt supply circuit is shorted to voltage, it is essential to check the wiring and connectors for any signs of corrosion or damage and repair or replace them as necessary. This will help prevent the code from being generated and ensure that the vehicle runs optimally.

CRANKCASE PRESSURE SENSOR SIGNAL CIRCUIT SHORTED TO THE 5-VOLT SUPPLY CIRCUIT
Suppose the crankcase pressure sensor signal circuit is shorted to the 5-volt supply circuit. In that case, inspect the wiring and connectors for any signs of corrosion or damage and repair or replace them as necessary. This will help prevent the code from being generated and ensure that the vehicle runs optimally.
SENSOR GROUND CIRCUIT OPEN/HIGH RESISTANCE
When the sensor ground circuit has an open or high resistance, it is important to check the wiring and connectors for any signs of corrosion or damage and repair or replace them as necessary. This will help prevent the code from being generated and ensure that the vehicle runs optimally.
CRANKCASE PRESSURE SENSOR
When the crankcase pressure sensor is faulty, replacing the sensor or cleaning the connections is essential. This will help prevent the code from being generated and ensure that the vehicle runs optimally.
POWERTRAIN CONTROL MODULE (PCM)
When the powertrain control module (PCM) is faulty, it is necessary to replace or reflash it. This will help prevent the code from being generated and ensure that the vehicle runs optimally.
