Question

2004 Jeep Wrangler Rubicon 4.0L with code P0432, where is this located and what needs to be fixed?

Answer 1

Description

indicate bank 2 catalyst system efficiency is below the acceptable threshold

Possible causes

ues of leaded fuel
damaged HO2s
malfunctioning ECT
high fuel pressure
damaged exhaust manifold
damaged catalytic converter
oil contamination
cylinder misfiring
downstream HO2S wires improperly connected
damage exhaust system pipe
damaged muffler/tailpipe assembly
retarded spark timing

Dignostic Aides

compare HO2S upstream and downstream switch rate. Under normal closed loop fuel conditions, highefficiency catalysts have oxygen storage which make the switching frequency of the downstream HO2S quete slow compared to the upetream HO2S
 

Answer 2

Continue

As catalyst efficiency deteriorates, its ability to store oxygen declines and the downstreams HO2S signal begins to switch mor rapidly approaching the switch rate of the upstream HO2S once beyond an acceptable limit the DTC is set
