What Does Code P0141 Mean? – A Comprehensive Guide

AvatarByCarl Frisch

Code P0141 is a Diagnostic Trouble Code (DTC) indicating an issue with the oxygen sensor heater circuit in Bank 1, Sensor 2 of the vehicle’s engine. The oxygen sensor heater circuit is responsible for pre-heating or heating up the oxygen sensor so that it can respond quickly to changes in the exhaust gas composition. When this code is stored, it means that the powertrain control module (PCM) has detected a voltage or resistance issue with the oxygen sensor heater circuit. This code can be triggered by a faulty oxygen sensor or wiring/connector issues between the PCM and the oxygen sensor. In order to resolve this issue, a qualified technician should diagnose and repair any wiring/connector issues and replace any faulty components as needed.
