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.

Step-by-Step Diagnostic Procedure
-
Measure Bank 2 VVT solenoid resistance. Infinite ohms confirms open coil failure.
-
Check connector is fully seated. Verify pins are not backed out or corroded.
-
Test wiring continuity from PCM to Bank 2 solenoid connector.
-
If wiring is good, replace the Bank 2 intake VVT solenoid.
