Question

need help anyone who has any info

Answer 1

P0520 Engine oil pressure (EOP) senor circuit

Start and runs for 3 seconds , this code may not be the reason for the engine to stall in 3 seconds, even with this code that most Impala has this code stored without any drivability problems , unless the oil pressure is truly low. Check the antitheft light  if it is illuminated as the vehicle is started the problem would be with the antitheft .
