Common Symptoms

  • Check Engine Light on
  • Poor performance from Bank 2 cylinders
  • Rough idle
  • Possible increase in exhaust emissions

Probable Causes (Ranked by Likelihood)

  • Open circuit in Bank 2 VVT solenoid wiring Very High
  • Failed Bank 2 VVT solenoid (open coil) High
  • Disconnected connector at Bank 2 solenoid Moderate
  • PCM Bank 2 driver open Low

Step-by-Step Diagnostic Procedure

  1. Measure Bank 2 VVT solenoid resistance. Infinite ohms confirms open coil failure.

  2. Check connector is fully seated. Verify pins are not backed out or corroded.

  3. Test wiring continuity from PCM to Bank 2 solenoid connector.

  4. If wiring is good, replace the Bank 2 intake VVT solenoid.

Frequently Asked Questions

What does circuit high mean for P0084?

Circuit high means the PCM sees an open circuit. No current flows through the solenoid, so Bank 2 intake valve timing cannot be adjusted.

How do I locate the Bank 2 VVT solenoid?

Bank 2 is the side of the engine without cylinder 1. On most V6 engines, the Bank 2 intake VVT solenoid is on the rear valve cover near the firewall.

Can wiring be more difficult on Bank 2?

Yes, Bank 2 is typically closer to the firewall and harder to access. Wiring inspection and repair may require removing intake components for access.
