P0432 (M)1/2 Catalytic Converter Efficiency. Catalyst 2/1 efficiency below required level.
P0432 - 2/1 CATALYTIC CONVERTER EFFICIENCY
As catalyst efficiency deteriorates, the switch rate of the downstream O2 sensor approaches that of the upstream O2 sensor. If at any point during the test the switch ratio reaches a predetermined value a counter is incremented by one.
-Catalytic converter 2/1 faulty
-Upstream O2 sensor older than downstream O2 sensor
-engine misfire or running condition
-large vacuum leak
-engine oil leakage into exhaust-valve guide, seals, piston rings
P0455 (M) Evap Leak Monitor Large. Leak Detected A large leak has been detected in the evaporative system.
Buy a new gas tank cap. Check the hoses and fittings from the Evap solenoid and LDP for loose hoses/fittings or damage.
Also check for disconnected or damaged wires.
