What Does Code P0153 Mean? DTC P0153 signifies an issue with the Bank 2 Sensor 1 oxygen sensor circuit, specifically indicating a slow response. Bank 2 refers to the cylinder bank that does not contain cylinder #1, and Sensor 1 denotes the upstream (pre-catalytic converter) oxygen sensor. This sensor is critical for the Engine Control […]

What Does Code P0154 Mean? The P0154 diagnostic trouble code signifies “O2 Sensor Circuit No Activity Detected (Bank 2 Sensor 1).” This code is registered by the Engine Control Module (ECM), also known as the Powertrain Control Module (PCM), when it monitors the signal voltage from the upstream oxygen sensor on engine Bank 2 and […]

What Does Code P0155 Mean? DTC P0155 signifies an detected malfunction within the heater circuit of the Oxygen (O2) Sensor located in Bank 2, Sensor 1. Bank 2 refers to the engine bank that does not contain cylinder #1, and Sensor 1 denotes the upstream, pre-catalytic converter oxygen sensor. The Engine Control Module (ECM) or […]

What Does Code P0156 Mean? The OBD-II diagnostic trouble code P0156 signifies an O2 Sensor Circuit Malfunction (Bank 2 Sensor 2). This indicates that the Powertrain Control Module (PCM), also known as the Engine Control Module (ECM), has detected an electrical anomaly or an implausible signal within the circuit for the oxygen sensor located after […]

What Does Code P0157 Mean? DTC P0157 signifies an issue with the electrical circuit of the downstream oxygen sensor on Bank 2, specifically indicating an O2 Sensor Circuit Low Voltage condition for Sensor 2. Bank 2 refers to the cylinder bank that does not contain cylinder #1 (often the passenger side on V-engines), and Sensor […]

What Does Code P0158 Mean? DTC P0158 indicates an “O2 Sensor Circuit High Voltage (Bank 2 Sensor 2)” condition. This signifies that the Engine Control Module (ECM), also known as the Powertrain Control Module (PCM), has detected a voltage reading from the downstream oxygen sensor on Bank 2 (the side of the engine that does […]

What Does Code P0159 Mean? DTC P0159, “O2 Sensor Circuit Slow Response (Bank 2 Sensor 2),” indicates that the Engine Control Module (ECM), also known as the Powertrain Control Module (PCM), has detected that the downstream oxygen sensor on Bank 2 is responding too slowly to changes in the exhaust gas oxygen content. Bank 2 […]

What Does Code P0160 Mean? DTC P0160 signifies “O2 Sensor Circuit No Activity Detected (Bank 2 Sensor 2)”. This code indicates that the Engine Control Module (ECM) or Powertrain Control Module (PCM) has not observed the expected voltage fluctuations or a consistent, reasonable voltage level from the downstream oxygen sensor on engine bank 2. Bank […]

What Does Code P0161 Mean? DTC P0161 signifies an detected malfunction within the heater circuit of the Oxygen (O2) sensor specifically designated as Bank 2 Sensor 2. To clarify, Bank 2 refers to the engine cylinder bank that does not contain cylinder number one. Sensor 2 denotes the downstream O2 sensor, positioned after the catalytic […]

What Does Code P0162 Mean? The OBD-II diagnostic trouble code P0162 signifies an O2 Sensor Circuit Malfunction (Bank 2 Sensor 3). This indicates that the Engine Control Module (ECM), also known as the Powertrain Control Module (PCM), has detected an electrical fault within the circuit connected to the third oxygen sensor in Bank 2 of […]
