What Does the P2058 Code Mean?
The P2058 code is defined as a Reductant Injection Valve Circuit High error. This means that the Powertrain Control Module (PCM) has detected a high voltage or an electrical fault in the reductant injection valve circuit, which is vital for the proper function of the vehicle’s emissions control system.
What Causes the P2058 Code?
Several factors can trigger the P2058 code, including:
- DEF injector failure
- Powertrain Control Module (PCM) failure
- Wiring issues
Diesel Exhaust Fluid (DEF) is injected into the exhaust stream to assist in converting harmful exhaust particles into harmless gases. If the DEF injector malfunctions, the system cannot operate correctly, leading to the P2058 code.
What Are the Symptoms of the P2058 Code?
Drivers may notice several symptoms indicating the presence of the P2058 code, including:
- Failure of the Diesel Particulate Filter (DPF) to regenerate
- Decreased engine performance
- Increased emissions
How Serious Is the P2058 Code?
The P2058 code is categorized as urgent, meaning that immediate action is necessary. Ignoring this code can lead to significant damage to the vehicle or pose risks to the driver and passengers due to increased emissions and potential engine performance issues.
How to Diagnose the P2058 Code
To properly diagnose the P2058 code, a mechanic should follow these steps:
- Use an OBD-II scanner to confirm the P2058 code.
- Inspect the wiring and connectors associated with the DEF injector for any signs of damage or corrosion.
- Test the DEF injector’s functionality to ensure it operates within the specified parameters.
- Check the PCM for any faults or updates that may be necessary.
Common Repairs for the P2058 Code
Repairs for the P2058 code may involve:
- Replacing the DEF injector if it has failed.
- Repairing or replacing damaged wiring or connectors.
- Reprogramming or replacing the Powertrain Control Module (PCM) if necessary.
How Much Does It Cost to Fix the P2058 Code?
The cost to fix the P2058 code can vary widely depending on the specific issue. On average, repairs might range from $100 to $1,500, depending on whether the DEF injector, wiring, or PCM needs replacement. Labor costs will also factor into the total expense.
Can I Fix the P2058 Code Myself?
While some DIY enthusiasts may be able to troubleshoot and repair minor wiring issues or replace the DEF injector, it is vital to have a thorough understanding of the vehicle’s emission system. If you are not confident in your abilities, it is recommended to seek professional help to avoid further complications.
