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…
What does the P0133 Oxygen Sensor Circuit Slow Response (Bank 1, Sensor 1) mean? P0133 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 1. When the P0133…
What does the P0132 Oxygen Sensor Circuit High Voltage (Bank 1, Sensor 1) mean? P0132 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 P0131 Oxygen Sensor Circuit Low Voltage (Bank 1, Sensor 1) mean? P0131 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 P0130 Oxygen Sensor Circuit Malfunction (Bank 1, Sensor 1) mean? P0130 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 P000D “B” Camshaft Position Slow Response Bank 2 mean? P000D indicates a “camshaft position slow response” issue. This means the camshaft isn’t aligning properly with the crankshaft, which can cause the engine to misfire by not timing the fuel injector and spark plug ignition correctly. Specifically, P000D points to the Exhaust camshaft…
