P2058 — Reductant Injection Valve Circuit High Bank 2 Unit 2

OBD2 code P2058 flags a problem with the sensor and actuator circuits (reductant injection valve circuit high bank 2 unit 2). The car is usually drivable while you plan the repair. Common culprits: control module driver fault, faulty sensor or actuator of the affected circuit, open or shorted wiring in the circuit.

powertrain (engine/transmission)

Is it safe to drive?

Short-term driving is OK In most cases the car remains drivable, possibly with reduced performance or a disabled auxiliary system. If symptoms include stalling, no-start or brake/steering warnings, treat it as urgent.

How to diagnose with an OBD scanner

  1. Read the code and freeze frame Connect an OBD2 scanner, confirm P2058 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
  2. Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
  3. Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the reductant injection valve circuit high bank 2 unit 2 for damage, corrosion, chafing or poor contact.
  4. Subsystem check Measure reference voltage, ground and signal continuity at the component connector.
  5. Subsystem check Wiggle-test the harness while watching the signal in live data — dropouts reveal broken wires.
  6. Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2058 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P2058 (parts and labor, USD, independent shop rates): Control module repair: $300–$1,000; Repair wiring or connectors: $80–$250; Replace the faulty sensor or actuator: $150–$500. Overall, fixing P2058 usually costs between $80 and $1,000. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

Common questions

What are the symptoms of P2058?

Drivers most often notice: increased fuel consumption in some cases, the affected system operates intermittently or not at all, Check Engine Light on, possible limp mode depending on the affected component.

What is the most common cause of P2058?

The most common causes are: control module driver fault, faulty sensor or actuator of the affected circuit, open or shorted wiring in the circuit.

How much does it cost to fix P2058?

Control module repair — $300–$1,000; Repair wiring or connectors — $80–$250; Replace the faulty sensor or actuator — $150–$500. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

What does P2058 mean?

Seeing P2058 on your scanner? The control unit has caught the sensor and actuator circuits operating outside its calibrated window. The formal description is “Reductant Injection Valve Circuit High Bank 2 Unit 2”, and the code is grouped under powertrain (engine/transmission) faults.

“Bank 2” means the side of the engine opposite to cylinder 1. Verify which side that is on your specific engine before testing or replacing parts.

The module monitors this system continuously while driving. When readings fall outside the expected range for a defined number of drive cycles, it stores P2058 and switches on the warning light. Freeze frame data saved with the code shows the exact conditions — rpm, load, temperature, speed — at the moment the fault was detected, which is the best starting point for diagnosis.

Common symptoms of P2058

  • increased fuel consumption in some cases
  • the affected system operates intermittently or not at all
  • Check Engine Light on
  • possible limp mode depending on the affected component

What causes P2058?

  • control module driver fault
  • faulty sensor or actuator of the affected circuit
  • corroded, loose or damaged connector
  • poor ground connection
  • open or shorted wiring in the circuit
