Decoding P0083: Intake Valve Control Solenoid Circuit High (Bank 2) GuideMechanic.Com In the realm of automotive diagnostics, the emergence of error codes has become an essential tool in identifying and resolving issues within modern vehicles.
One such diagnostic trouble code (DTC) is P0083, which specifically points to a problem in the intake valve control solenoid circuit of Bank 2.
In this article, we will explore the intricacies of P0083, understand its implications, delve into potential causes, and discuss diagnostic procedures and remedies to address this issue effectively.

Understanding P0083:
P0083 is an OBD-II trouble code that denotes a malfunction in the intake valve control solenoid circuit high in Bank 2. Within engines featuring variable valve timing (VVT), the intake valve control solenoid regulates the timing of the intake valves, optimizing engine performance under varying operating conditions.
Bank 2 refers to the bank of cylinders opposite to Bank 1 in V-engine configurations, commonly found in V6, V8, and other multi-cylinder engines.
Causes of P0083:
Several factors can contribute to the occurrence of the P0083 error code:
- Faulty Intake Valve Control Solenoid: A malfunctioning or defective intake valve control solenoid can lead to irregularities in the circuit’s voltage, resulting in a high voltage condition and triggering the P0083 code.
- Wiring Issues: Damage, corrosion, or poor connections within the wiring harness connecting the intake valve control solenoid to the engine control module (ECM) can disrupt electrical signals, leading to a high voltage condition in the circuit.
- Excessive Battery Voltage: Higher-than-normal voltage supply from the vehicle’s battery or alternator can cause a high voltage condition in the intake valve control solenoid circuit, prompting the ECM to set the P0083 code.
- Engine Oil Contamination: Contaminated or degraded engine oil can hinder the proper operation of the VVT system, affecting the performance of the intake valve control solenoid and potentially leading to the detection of the P0083 fault code.
- ECM Malfunction: A malfunctioning engine control module may misinterpret signals from the intake valve control solenoid circuit, erroneously detecting a high voltage condition and setting the P0083 code.

Diagnosing the root cause of the P0083 code requires a systematic approach:
- OBD-II Scan: Utilize an OBD-II scanner to retrieve the stored trouble codes, including P0083. Analyze accompanying freeze frame data to gain insights into the conditions present when the fault occurred.
- Visual Inspection: Conduct a visual inspection of the intake valve control solenoid, its wiring harness, and connectors. Look for signs of damage, corrosion, or loose connections. Repair or replace components as needed.
- Solenoid Operation Test: Employ a multimeter to test the resistance of the intake valve control solenoid according to manufacturer specifications. Additionally, verify proper voltage and ground signals when the engine is running.
- Battery Voltage Check: Measure the voltage output of the vehicle’s battery and alternator to ensure they are operating within the manufacturer’s specified range. Excessive battery voltage can contribute to a high voltage condition in the intake valve control solenoid circuit, triggering the P0083 code.
- Engine Oil Examination: Inspect the engine oil level and condition. Ensure that the oil is clean, at the correct level, and meets the manufacturer’s specifications. Contaminated or low-quality oil can impair the operation of the VVT system and lead to fault codes like P0083.
Rectifying P0083:
Once the underlying cause of the P0083 code has been identified, appropriate measures can be taken to address the issue:
Replace Faulty Components: If the intake valve control solenoid or wiring is found to be defective, replace them with genuine OEM parts to restore proper functionality.
Repair Wiring: Repair any damaged or corroded wiring in the intake valve control solenoid circuit, ensuring secure connections and proper insulation to prevent future issues.
Voltage Regulation: Implement measures to regulate excessive voltage supply from the vehicle’s battery or alternator, such as installing a voltage regulator or replacing faulty components.
Engine Oil Change: If engine oil contamination is determined to be a contributing factor, perform an oil change using the manufacturer’s recommended oil grade and viscosity. Regular oil changes at specified intervals help maintain optimal engine performance.
Reset ECM: After addressing the root cause of the P0083 code, use an OBD-II scanner to clear the trouble codes and reset the engine control module. This allows the ECM to relearn corrected parameters and monitor system operation for any further issues.
