P2169Exhaust Pressure Regulator Vent Solenoid Control Circuit/Open
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- The name points to a solenoid that lets an exhaust pressure regulator vent, but the only public, code-exact use found is on Jaguar Land Rover petrol models, where this code family belongs to the active exhaust valve: a solenoid in the tailpipe section switches a flap between quiet and sport sound. P2169 is the open or general fault of its control line. Land Rover documented P2169-13 (fault type 13 = open circuit) on the 2016 LR4 with the 3.0 supercharged V6 in bulletin SSM72392: the car configuration file enabled a valve that was never fitted, so the module saw an open circuit; reconfiguring cures it. Real cases mean a broken wire, loose plug or burnt-out coil. Exhaust pressure control valves, typical for diesels, have their own range P0475 to P0478. P2170 and P2171 cover the low and high faults.
