What causes 02 sensor code?
What causes 02 sensor code?
Deceptive Oxygen Sensor Codes Engine vacuum leaks that create a lean exhaust condition. Mass airflow sensor failure that creates a rich exhaust condition. Manifold air pressure sensor failure that creates a rich exhaust condition. A defective fuel pressure regulator.
What does the O2 sensor code p0140 mean?
P0140 is the OBD-II generic code which indicates that the O2 sensor for Bank 1, Sensor 2 failed respond to the fuel cutoff or fuel enrichment signals by the Engine Control Module (ECM). What causes the P0140 code?
What is the diagnostic code for O2 sensor no activity?
P0140 is a diagnostic trouble code (DTC) for “O2 Sensor Circuit No Activity Detected (Bank 1, Sensor 2)”.
Why is the O2 sensor no activity in bank 1?
If there is no response from the O2 sensor for Bank1, Sensor, no response indicates that there is no change of voltage between 410 to 490 mV for over 74 seconds (from the fuel enrichment signals or fuel cut off as signaled by the ECM). The possibility of the ECM not working well inside the 02 circuits.
What does the code p0134 on bank 1 mean?
The code indicates that your car’s primary computer, which is often referred to as the powertrain control module (PCM), has detected inactivity from the upstream oxygen sensor (O2) on Bank 1. Inactivity from the upstream oxygen sensor can trigger code P0134.

What happens if O2 sensor does not respond to fuel cutoff?
If the O2 sensor does not respond to fuel cutoff or fuel enrichment signals from the ECM, it will be deemed inactive Additionally, the EMC will not detect the O2 sensor if the mass airflow sensor and O2 sensor’s readings are miscalculated or if the ECM itself is malfunctioning
