The 2026 Honda Prelude in Boise may present a range of OBD-II codes—P0171 (lean condition), P0420 (catalyst efficiency), P0300 (misfire), and P0133 (oxygen sensor sluggish) are common examples. Left unchecked, each can lead to escalating costs: a persistent lean condition can damage the catalytic converter, turning a modest sensor replacement into a large exhaust repair; a misfire left unattended risks engine damage and poor fuel economy; and failing oxygen sensors reduce performance and increase emissions.
