What does the P0153 Oxygen Sensor Circuit Slow Response (Bank 2, Sensor 1) mean? P0153 code gets triggered when the Engine Control Module detects that the voltage from the oxygen sensor—also known as the air-fuel ratio sensor—is slower than expected. Specifically, we’re talking about the oxygen sensor for Bank 2, Sensor 1. When the P0153…
What does the P0152 Oxygen Sensor Circuit High Voltage (Bank 2, Sensor 1) mean? P0152 code gets triggered when the Engine Control Module detects that the voltage from the oxygen sensor—also known as the air-fuel ratio sensor—has remained too high for too long. This high voltage usually indicates that the sensor is detecting a rich…
What does the P0151 Oxygen Sensor Circuit Low Voltage (Bank 2, Sensor 1) mean? P0151 code gets triggered when the Engine Control Module detects that the voltage from the oxygen sensor—also known as the air-fuel ratio sensor—has remained below 400 molts for more than 20 seconds, causing the engine to run either too rich or…
What does the P0150 Oxygen Sensor Circuit Malfunction (Bank 2, Sensor 1) mean? P0150 code gets triggered when the Engine Control Module detects that the voltage from the oxygen sensor—also known as the air-fuel ratio sensor—has stayed in a lean condition for too long, causing the engine to either run too rich or too lean….
What does the P0140 Oxygen Sensor Circuit No Activity Detected (Bank 1, Sensor 2) mean? P0140 code gets triggered when the Engine Control Module has detected inactivity from the oxygen sensor, also known as the air-fuel ratio sensor. This inactivity typically indicates that the oxygen sensor isn’t sending voltage signals back to the ECM, often…
What does the P0139 Oxygen Sensor Circuit Slow Response (Bank 1, Sensor 2) mean? P0139 code gets triggered when the Engine Control Module detects that the voltage from the oxygen sensor—also known as the air-fuel ratio sensor—is slower than expected. Specifically, we’re talking about the oxygen sensor for Bank 1, Sensor 2. When the P0139…
What does the P0138 Oxygen Sensor Circuit High Voltage (Bank 1, Sensor 2) mean? P0138 code gets triggered when the Engine Control Module detects that the voltage from the oxygen sensor—also known as the air-fuel ratio sensor—has remained too high for too long. This high voltage usually indicates that the sensor is detecting a rich…
What does the P0137 Oxygen Sensor Circuit Low Voltage (Bank 1, Sensor 2) mean? P0137 code gets triggered when the Engine Control Module detects that the voltage from the oxygen sensor—also known as the air-fuel ratio sensor—has remained below 400 milli volts for more than 20 seconds, causing the engine to run either too rich…
What does the P0136 Oxygen Sensor Circuit Malfunction (Bank 1, Sensor 2) mean? P0136 code gets triggered when the Engine Control Module detects that the voltage from the oxygen sensor—also known as the air-fuel ratio sensor—has stayed in a lean condition for too long, causing the engine to either run too rich or too lean….
What does the P0134 Oxygen Sensor Circuit No Activity Detected (Bank 1, Sensor 1) mean? P0134 code gets triggered when the Engine Control Module has detected inactivity from the oxygen sensor, also known as the air-fuel ratio sensor. This inactivity typically indicates that the oxygen sensor isn’t sending voltage signals back to the ECM, often…
