Intake Valve Control Circuit Low (Bank 2)
Powertrain Emission Controls Variable Valve Timing 🟡 Moderate — Fix within a week
💬
What This Actually Means
In plain language — no jargon

The engine computer detects that the intake valve control solenoid on bank 2 isn't receiving enough electrical power. Think of it like a dimmer switch that's stuck too low—the valve needs full power to open and close properly.

Embedded Systems Insight
What the ECU/ECM is actually computing

The ECM monitors the voltage and current supplied to the intake valve control solenoid (Bank 2) during operation. It expects a specific voltage range when the solenoid is commanded on; if the measured voltage drops below the minimum threshold, it indicates a circuit resistance problem or wiring fault.

Voltage & Parameter Thresholds

Parameter Normal Range Fault Condition
Solenoid Control Voltage 11-14V when energized Below 8V or open circuit
Solenoid Current Draw 0.5-2.0 Amps Below 0.2A or no response

Diagnostic & DIY Fix Guide
Check these in order — from cheapest to most complex
1
Wiring harness and connectors
Inspect and clean the solenoid connector on bank 2 for corrosion, loose pins, or damaged wires.
2
Intake valve control solenoid (Bank 2)
Test solenoid resistance with a multimeter; replace if resistance is outside 5-8 ohms range.
3
ECM or PCM relay
Check the relay controlling solenoid power supply; swap with identical relay to test or replace if faulty.
