Jeep Code P0058 is an O2-SENSOR 2/2 HEATER CIRCUIT HIGH code indicating a malfunction in the Oxygen (O2) Sensor Heater Control system. This system is designed to allow the system to enter the Closed Loop quickly and meet the OBD II requirements for continuous monitoring and to deliver accurate readings. It is accomplished by the Powertrain Control Module (PCM) sending a Pulse Width Modulated (PWM) current to the O2 Sensors heater element.
The PWM duty cycle is calculated in response to the temperature measurements. If the code is triggered, it could be caused by an O2 SENSOR 2/2 HEATER CONTROL CIRCUIT SHORTED TO VOLTAGE, O2 SENSOR 2/2 HEATER CONTROL CIRCUIT OPEN/HIGH RESISTANCE, O2 SENSOR GROUND CIRCUIT OPEN/HIGH RESISTANCE, O2 SENSOR 2/2, or a faulty POWERTRAIN CONTROL MODULE (PCM).

Causes and Solutions for Jeep Code P0058
| Cause | Solution |
|---|---|
| O2 SENSOR 2/2 HEATER CONTROL CIRCUIT SHORTED TO VOLTAGE | Verify the wiring harness, check the ground connection, and ensure the fuse is not blown. |
| O2 SENSOR 2/2 HEATER CONTROL CIRCUIT OPEN/HIGH RESISTANCE | Inspect the wiring harness, check the O2 Sensor 2/2 heater element, and look for open circuits. |
| O2 SENSOR GROUND CIRCUIT OPEN/HIGH RESISTANCE | Examine the O2 Sensor ground circuit for any signs of corrosion and verify the ground connection is secure. |
| O2 SENSOR 2/2 | Replace the O2 Sensor 2/2 or inspect the harness for any loose or damaged wiring. |
O2 SENSOR 2/2 HEATER CONTROL CIRCUIT SHORTED TO VOLTAGE
When a Jeep Code P0058 is triggered due to an O2 Sensor 2/2 Heater Control Circuit Shorted to Voltage, the wiring harness should be verified for any damaged components. Also, the ground connection should be checked to ensure the fuse is not blown.
O2 SENSOR 2/2 HEATER CONTROL CIRCUIT OPEN/HIGH RESISTANCE
The harness should be inspected for any loose or damaged wiring when this code is triggered due to an O2 Sensor 2/2 Heater Control Circuit Open/High Resistance. The O2 Sensor 2/2 heater element should also be checked for any open circuits.

O2 SENSOR GROUND CIRCUIT OPEN/HIGH RESISTANCE
If the Jeep Code P0058 is caused by an O2 Sensor Ground Circuit Open/High Resistance, the O2 Sensor ground circuit should be examined for any signs of corrosion. Additionally, the ground connection should be verified to ensure security.
O2 SENSOR 2/2
If the code is caused by an O2 Sensor 2/2, the sensor should be replaced, or the wiring harness should be inspected for any loose or damaged wiring.
Conclusion
In conclusion, Jeep Code P0058 is an O2-SENSOR 2/2 HEATER CIRCUIT HIGH code indicating a malfunction in the Oxygen (O2) Sensor Heater Control system. It could be caused by an O2 SENSOR 2/2 HEATER CONTROL CIRCUIT SHORTED TO VOLTAGE, an O2 SENSOR 2/2 HEATER CONTROL CIRCUIT OPEN/HIGH RESISTANCE, an O2 SENSOR GROUND CIRCUIT OPEN/HIGH RESISTANCE, or an O2 SENSOR 2/2. To solve this issue, the wiring harness should be verified, the ground connection should be checked, the fuse should be inspected, the O2 Sensor 2/2 heater element should be checked, and the O2 Sensor ground circuit should be examined. If necessary, the O2 Sensor 2/2 should be replaced, or the wiring harness should be inspected. Knowing the causes and solutions for Jeep Code P0058 can help diagnose and fix the problem quickly and accurately.
