P0083 — Intake Valve Control Solenoid Circuit High (Bank 2)
OBD2 code P0083 flags a problem with the sensor and actuator circuits (intake valve control solenoid circuit high (bank 2)). The car is usually drivable while you plan the repair. Common culprits: poor ground connection, faulty sensor or actuator of the affected circuit, control module driver fault.
powertrain (engine/transmission)
Is it safe to drive?
Caution P0083 can reduce or disable intake-valve control on Bank 2, affecting idle quality, power, and emissions. If the Check Engine Light is accompanied by rough running, hesitation, or other fault codes, avoid heavy or extended driving and arrange prompt diagnosis.
Typical symptoms
- Check Engine Light with P0083 stored in the powertrain system
- Rough, uneven, or slightly unstable idle from reduced Bank 2 intake-valve control
- Hesitation or stumble during acceleration
- Reduced engine power, especially under load
- Possible reduced throttle response or fail-safe operation
- No obvious drivability symptom on some vehicles, with P0083 appearing only in scanner memory
Common causes
- Open or high-resistance wiring in the Bank 2 intake valve control solenoid circuit, causing the controller to detect excessive voltage and set P0083
- A failed or internally open Bank 2 intake valve control solenoid winding
- Corroded, loose, water-contaminated, or damaged terminals at the solenoid or engine control module connector
- A short to constant battery voltage in the solenoid control wiring
- A poor solenoid ground or reference path on vehicles that use ground-side solenoid control
- An engine control module output driver fault after the wiring, connectors, and solenoid have been ruled out
How to diagnose with an OBD scanner
- Confirm P0083 with an OBD2 scanner Connect an OBD2 scanner through an ELM327 adapter or use AIScanAuto to read stored and pending codes. Confirm P0083, capture its freeze-frame data, and note engine speed, load, battery voltage, and whether the code returns immediately.
- Inspect the Bank 2 circuit Using the service wiring diagram, inspect the intake valve control solenoid, its connector, and the harness between it and the engine control module. Look for corrosion, water, loose terminals, burned pins, chafing, or wires damaged near hot or moving components.
- Test the intake valve control solenoid With the ignition off and the battery disconnected when required by the service procedure, measure resistance across the solenoid terminals. Compare the reading with the specified value; an open circuit or excessive resistance indicates a defective solenoid.
- Check for shorts and high-resistance connections Back-probe the solenoid and controller connectors while following the wiring diagram. Check the control path for short-to-battery voltage, intermittent opens, and excessive resistance at grounds or splices. Normal wiring with an abnormal P0083 signal requires further module testing.
- Repair and verify the P0083 fault Repair the damaged circuit or connector, or replace the solenoid if it fails testing. Clear P0083 with the scanner, cycle the ignition, road-test the vehicle, and confirm that neither an active nor pending P0083 returns. Review commanded and actual intake-valve control data if the scanner supports those parameters.
Approximate repair cost
A typical independent-shop estimate for diagnosing and repairing P0083 is about $180-$550, depending on whether the fault is a solenoid, connector, or accessible wiring problem. PCM or extensive harness work can cost more. Figures are estimates and vary by region.
Common questions
What exactly does P0083 mean?
P0083 means the controller detected abnormally high voltage in the Bank 2 intake valve control solenoid circuit, commonly caused by an open connection, short to power, or defective solenoid.
What is the most common cause of P0083?
The usual causes are a damaged wire, corroded connector, or internally open solenoid. A short to battery voltage or a controller driver fault are less common possibilities.
Can I safely drive with P0083 stored?
You may drive cautiously if the engine runs normally, but intake-valve control may be limited. Avoid sustained high load if there is hesitation, rough idle, reduced power, or additional warning codes, and repair the fault promptly.
How much does it usually cost to repair P0083?
Independent-shop P0083 repair commonly falls around $180-$550 for diagnosis and a solenoid or basic wiring repair. Prices vary by region, and harness or engine control module work can increase the total.
When your engine control unit detects a problem with the intake valve control solenoid on the exhaust side of the engine, it logs OBD2 code P0083. This specific fault relates to a high electrical condition in the circuit — essentially the system is reporting that voltage or resistance has gone outside acceptable parameters. The full technical definition reads "Intake Valve Control Solenoid Circuit High (Bank 2)." This code falls within the powertrain category, meaning it directly affects engine operation or emissions systems.
Bank 2 refers to the engine bank that does not contain cylinder number one. Before attempting any diagnosis or repair, you need to verify which bank that represents on your particular engine configuration. This matters because the solenoid in question controls variable valve timing or lift on that specific bank. The ECU continuously monitors this circuit while the engine runs. When sensor and actuator signals fail to match expected values across multiple drive cycles, the module stores P0083 and illuminates the check engine light. Freeze frame data captured alongside the code shows the exact engine operating conditions — RPM, load, temperature, and vehicle speed — when the fault first appeared, giving you the best starting point for your investigation.
The intake valve control solenoid manages valve timing to optimize performance, fuel economy, and emissions across different driving conditions. When this solenoid's electrical circuit registers a high condition, the system can no longer adjust valve timing properly. Depending on your vehicle's design, this may trigger a default mode with reduced functionality rather than complete failure. Understanding the circuit's operation helps you recognize why the ECU flags this condition and what it means for drivability.
Common Symptoms of P0083
- The intake valve control system operates inconsistently or stops working entirely
- Check Engine Light remains illuminated
- Noticeable increase in fuel consumption under normal driving
- Engine enters reduced-power limp mode depending on which component failed
- Possible hesitation or rough running during acceleration
- Reduced overall engine performance in some vehicle applications
What Causes P0083?
- Blown fuse protecting the intake valve control solenoid circuit
- Faulty solenoid or associated sensor on Bank 2
- Failed driver circuit within the engine control module
- Wiring issue such as an open circuit or short to voltage
- Corroded, loose, or physically damaged electrical connector
- Insufficient ground connection at the component
- Chafed wiring harness insulation causing intermittent shorts
How to Diagnose P0083
-
Connect an OBD2 scanner and confirm P0083 is stored in the ECU. Save all freeze frame data before clearing anything — this snapshot of engine conditions when the fault occurred is invaluable for recreating the problem during testing.
-
Pull any additional stored trouble codes. Related codes often point to the root cause rather than the symptom. Also search for manufacturer technical service bulletins related to P0083 on your specific make and model, as many issues have documented factory solutions or software updates available through official channels.
-
Perform a thorough visual inspection of the wiring harness and connectors feeding the Bank 2 intake valve control solenoid. Look for damaged insulation, corroded pins, pushed-out terminals, and any signs of moisture intrusion or heat damage.
-
At the solenoid connector, measure reference voltage, ground circuit resistance, and signal wire continuity using a multimeter. Compare your readings against manufacturer specifications if available.
-
Conduct a wiggle test on the harness while monitoring live data on your scanner. Any signal dropouts or code reappearance during movement indicate broken wires inside the insulation that may not be visible externally.
-
After clearing the code, drive the vehicle through a complete drive cycle that reproduces the conditions recorded in the freeze frame data. If P0083 returns, you have confirmed an active fault requiring repair.

How Much Does It Cost to Fix P0083?
Total repair cost varies significantly depending on which component actually failed. For P0083 specifically, here are typical scenarios including parts and labor at independent shop rates in USD. If the issue turns out to be damaged wiring or a bad connector, expect to pay between $80 and $250 for repair. Replacing a faulty solenoid or related sensor typically runs $150 to $500 depending on your vehicle and part source. Control module issues represent the most expensive scenario at $300 to $1,000, sometimes requiring reprogramming or replacement. Overall, fixing P0083 usually falls somewhere between $80 and $1,000. Proper diagnosis before purchasing parts is essential — the most expensive repair is rarely the culprit, and an accurate diagnosis saves money by preventing unnecessary part purchases.
Can You Drive with P0083?
Most vehicles remain drivable when P0083 is stored, though you may notice decreased performance or reduced fuel efficiency. In many cases, the engine control module activates a fallback mode that maintains basic operation while disabling the affected auxiliary function. If the vehicle exhibits stalling, failure to start, or warnings affecting braking or steering systems, treat the situation as urgent and seek immediate repair. Otherwise, scheduling service within a reasonable timeframe is appropriate.
