When it comes to diagnosing vehicle issues, Chrysler Code P0058 is one of the most common codes to be identified. This code is indicative of an issue with the Oxygen (O2) Sensor Heater Control, a component of the vehicle’s powertrain. The aim of this component is to achieve the fastest possible temperature rise and to maintain a steady state temperature of the O2 Sensor in order to allow the system to enter closed loop quickly and meet the OBD II requirements for continuous monitoring. In order to fix the issue, it is important to understand the underlying causes, which can range from an O2 SENSOR 2/2 HEATER CONTROL CIRCUIT OPEN/HIGH RESISTANCE to a malfunctioning POWERTRAIN CONTROL MODULE (PCM). To get a better understanding of the issue, it is important to consult the related Service Bulletins.
Causes and Solutions for Chrysler Code P0058
| Cause | Solution |
|---|---|
| O2 SENSOR 2/2 HEATER CONTROL CIRCUIT OPEN/HIGH RESISTANCE | Check the resistance in the O2 Sensor 2/2 Heater Control Circuit |
| O2 SENSOR 2/2 HEATER GROUND CIRCUIT OPEN/HIGH RESISTANCE | Measure the resistance in the O2 Sensor 2/2 Heater Ground Circuit |
| O2 SENSOR 2/2 HEATER CONTROL CIRCUIT SHORTED TO VOLTAGE | Inspect the O2 Sensor 2/2 Heater Control Circuit for any possible shorts |
| POWERTRAIN CONTROL MODULE (PCM) | Replace the PCM if necessary |
O2 SENSOR 2/2 HEATER CONTROL CIRCUIT OPEN/HIGH RESISTANCE
When it comes to diagnosing the O2 Sensor 2/2 Heater Control Circuit, the first step is to check the resistance of the circuit. If the resistance is higher than the specified value, it can indicate that the circuit is open or has high resistance. In such cases, the circuit should be inspected for any damaged or corroded wiring, or any other issue that can cause the resistance to be higher than normal.
O2 SENSOR 2/2 HEATER GROUND CIRCUIT OPEN/HIGH RESISTANCE
If the O2 Sensor 2/2 Heater Ground Circuit is suspected to be the cause of the issue, then the resistance of the circuit should be measured. If the resistance is higher than the specified value, it can indicate that the circuit is open or has high resistance. In such cases, the circuit should be inspected for any damaged or corroded wiring, or any other issue that can cause the resistance to be higher than normal.
O2 SENSOR 2/2 HEATER CONTROL CIRCUIT SHORTED TO VOLTAGE
If the O2 Sensor 2/2 Heater Control Circuit is found to be shorted to voltage, then the circuit should be thoroughly inspected for any wiring or component that may be causing the short. Any damaged or corroded wiring should be replaced and all components should be tested to ensure proper operation.
POWERTRAIN CONTROL MODULE (PCM)
If the issue is found to be caused by the Powertrain Control Module (PCM), then it should be replaced. The PCM is responsible for controlling the various engine and transmission systems and any malfunction in the module can lead to various issues including Chrysler Code P0058.
Conclusion
Chrysler Code P0058 is an issue related to the Oxygen (O2) Sensor Heater Control, a component of the vehicle’s powertrain. To diagnose and fix the issue, it is important to understand the underlying causes, which can range from an O2 SENSOR 2/2 HEATER CONTROL CIRCUIT OPEN/HIGH RESISTANCE to a malfunctioning POWERTRAIN CONTROL MODULE (PCM). Depending on the cause, different solutions should be applied to ensure the proper functioning of the system and to avoid further issues. By following the solutions outlined in this article, it is possible to effectively diagnose and repair Chrysler Code P0058.
