P2094"B" Camshaft Position Actuator Control Circuit Low (Bank 2)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P2094 belongs to the fourth phaser valve of a twin-phaser V engine: actuator B, the exhaust camshaft, on bank 2. It is therefore absent on single-cam pushrod V8s and on inline engines. On GM's 3.6 L LFX the high-side output is checked for a ground short while on and treated as Type A after 20 out of 25 samples of 250 ms (19OBDG03B). The low-side GM controller of table 23OBDG07 detects the short to ground while off and reacts within 0.2 s; the lamp follows on the second trip. Ford's 2014 petrol list carries P2094 for the continuous monitor only. CARB requires output components of the valve timing system to be checked for circuit faults. An open circuit on this valve is P0023, wrong exhaust timing on bank 2 P0024 or P0025.
- What you may notice
- Engine warning lamp on
- Slight loss of efficiency, higher part-load emissions
- Likely causes
- LikelyBank 2 exhaust valve wire shorted to ground
- PossibleShorted coil in the bank 2 exhaust oil control valve
- RareInsulation damaged by heat near the exhaust manifold
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
