P2384 EGR Sensor D Circuit Intermittent
Same as P2381 but the signal is intermittent - typically a connector or harness fault. EGR mixes inert exhaust into intake to lower combustion peak temperature — too little raises NOx, too much causes misfires and rough running.
Is it safe to drive with P2384?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
