P2095 closes the series: the bank 2 exhaust phaser valve (actuator B) shows a high level on its control line. For the 3.6 L LFX, GM table 19OBDG03B describes a high-side driver that finds a short to supply with the output off and sets a Type A code after 20 failures in 25 samples. In table 23OBDG07 a low-side controller watches the pin while the driver is on and confirms the short to power after 1 s, Type B style with two trips. Ford's 2014 petrol list contains P2095 with lamp marking, monitored continuously. In the workshop, measure the valve coil, then check the control wire for voltage with the connector unplugged and the ignition on; any voltage there points to the harness, not the valve. The engine runs on with a fixed exhaust cam. P2094 is the Low counterpart, P0023 the open circuit.

Likely causes

Bank 2 exhaust valve wire shorted to a supply wire
Bridged pins in the valve or engine harness connector
ECM output stage defective

Symptoms

  • Engine warning lamp on
  • Exhaust cam on bank 2 fixed, minor drop in performance
