Where Is The Sensor Located Bank 2 P0430 After Cat Or Before P0430 code: catalyst system efficiency below threshold. The obd2 data trouble code p0430 is stored in memory when the ecu detects a low efficiency in the catalyst system for bank #2 (the bank of cylinders not containing cylinder #1). the ecu determines the efficiency of the catalytic converter (cat) using two sensors: the upstream oxygen sensor, located before the cat, and the downstream oxygen.

P0430 вђ Catalyst System Low Efficiency Bank 2 Chevrolet Code p0430 means that the downstream oxygen sensor from the catalytic converter on bank 2 detects the cat isn’t operating to efficiency standards, based on factory specifications. the p0430 trouble code is considered generic, meaning it occurs on vehicles of any type and model. the p0430 shows a problem with the emissions system. For a faulty oxygen sensor, it could be the result of a loose electrical connection, frayed wiring or a dirty or damaged sensor. carefully inspect your bank two oxygen sensor for oily grime or damage. either way, you may also want to inspect your other oxygen sensors for similar issues. a damaged catalytic converter requires replacement. P0430 specifically means: "p" indicates a powertrain related code. "0" denotes a generic obd ii code. "4" refers to the auxiliary emissions controls. "30" identifies the specific issue (catalyst system efficiency below threshold on bank 2) the code is triggered when the engine control module (ecm) detects that the catalytic converter on bank 2. The p0420 and the p0430 codes are caused by catalyst inefficiency. replacing your catalytic converter is costly, so, knowing if a new catalytic converter is needed pays off. your car’s exhaust system (below) comprises: a catalytic converter (s), at least two oxygen sensors and exhaust pipes that route the engine’s exhaust from the engine.
