P2092 is the Low fault of the intake phaser valve (actuator A) on bank 2, which exists only on V and boxer engines with a separate valve per bank. Bank 2 is the side without cylinder 1. GM's 3.6 L LFX V6 in table 19OBDG03B checks this output with the high-side logic known from bank 1: a short to ground while energised, below 0.5 ohms, 20 bad samples out of 25, Type A, lamp in the first trip. The low-side controller in GM table 23OBDG07 tests the line while switched off and confirms after 0.2 s. Ford's 2014 petrol list includes P2092 but marks it only for the continuous monitor, not for the key-on or running self-test. If only bank 2 reports a fault, compare the valve resistance with the bank 1 valve and look for chafing where the harness crosses the cylinder head.

Likely causes

Bank 2 intake valve wire shorted to ground on the cylinder head
Shorted coil in the bank 2 intake oil control valve
Oil inside the valve connector

Symptoms

  • Engine warning lamp on, immediately on GM LFX
  • Uneven running between banks, weaker torque
