Jan 26, 2025 · P0165 code indicates a problem with the oxygen sensor circuit, specifically for Bank 2 Sensor 3. If the heater fails, the O2 sensor may still give feedback to the ECM but Jan 23, 2023 · And sensor 1 means that this is the first O2 sensor mounted on the exhaust manifold. Diagnostic trouble code (DTC) P0135 stands for “Oxygen O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1). Categories: OBD Codes Feb 1, 2025 · The P0052 code typically points to issues with the oxygen sensor heater control circuit for Bank 2 Sensor 1. Other codes such as P0141 and P0136 can also be triggered due to problems involving oxygen sensors or their circuits across different banks. The oxygen sensor plays a critical role in monitoring exhaust gases and regulating fuel efficiency. P0063 code signals an issue with the heated oxygen sensor (HO2S) heater control circuit for Bank 2 Sensor 3. Jan 18, 2024 · P0135 – Heater circuit bank 1, sensor 1 issue; P0141 – Sensor heater circuit malfunction; P0155 – O2 signal slow response bank 2, sensor 1; Codes point accurately toward sensor, wiring, and connector faults. It indicates If the engine control module detects that the oxygen sensor heater circuit is open, short, or draws too much current based on coolant temperature, the onboard computer will output OBD-II diagnostic trouble code P0135. Mar 21, 2024 · One of the most common bad oxygen sensor symptoms is a check engine light on your dashboard. Oct 7, 2023 · How To Know If The Upstream Oxygen Sensor Is Bad.
