Services Performed
  • Scanned vehicle found code P0430 (Bank 2 Cat Efficiency Below Threshold). Raised vehicle and inspected air fuel ratio sensor and downstream oxygen sensor, both sensors are ok. Checked live data and found sensors are reading and responding, but bank 2 air fuel ratio is varying more than it should. During testing noted smoke coming from tail pipe that smelled of unburnt fuel or oil. Removed engine cover and inspected. Note: Engine cover is cracked. Found intake plenum bolts are shiny and show evidence of recent removal. Ignition coils have been numbered and coil on cylinder #5 is new. Need to physically inspect exhaust, intake, and spark plugs. Further diagnosis is required. If customer has service history of vehicle, it may help narrow down possible cause of excess combustives.
