P0140 code means the rear 02 sensor behind the catalytic convertor has an open circuit. It says no communication from the rear 02 sensor. The rear 02 sensor is also called sensor 2, whether it be bank 1 or bank 2. Hope this helps.
Trouble code P0140 means:O2 sensor circuit no activity detected (Bank 1 Sensor 2)
Trouble code P0140 means:O2 sensor circuit no activity detected (Bank 1 Sensor 2)
Trouble code P0140 means:O2 sensor circuit no activity detected (Bank 1 Sensor 2)
Trouble code P0140 means: O2 Circuit No Activity Detected (Bank 1, Sensor 2)
Bad O2 sensor-no activity detected.
No it will not.
did you mean code P0140 ? this means o2 sensor no activity( bank 1 sensor 2) in other words replace the O2 sensor. hope this answers your question.
The codes P0122, P0140, and P0141 for a 1999 Buick Park Avenue indicate issues related to the throttle position sensor (TPS) and the oxygen sensor (O2). P0122 signifies a low voltage signal from the TPS, which can affect engine performance. P0140 indicates a lack of activity or signal from the O2 sensor, while P0141 points to a malfunction in the heater circuit of the same sensor. These codes suggest potential problems with fuel management and emissions control, requiring diagnostic evaluation and possible repairs.
All sensors give a code when the sensor is not working right
It means there is bad/no connection between the car's computer and the oxygen sensor after the catalytic converter.
P= Powertrain 0140= bad oxygen sensor downstream from the catalytic converter. Check wiring first, if no problems with broken wiring replace sensor.
These codes are for the O2 Sensor - One is for the heater core inside the O2 Sensor, the other is the sensor. It's gone bad! - No Activity, is what it will read. It's the (Bank 1 Sensor 2) Not sure where it's located, ibelieve it's right in front of the Cat. good luck.
