What is O2 sensor heater circuit malfunction?
What Does the Code P0141 Mean? DTC P0141 stands for “Oxygen Sensor Heater Circuit Malfunction (Bank 1, Sensor 2).” It indicates that there’s a problem with the heater circuit of engine bank 1’s downstream O2 sensor. Your car’s PCM tests the oxygen sensors’ heater circuits for integrity.
How much does it cost to fix P0141?
Depending on the shop’s labor rate, this typically costs somewhere between $75-$150. Many, if not most, shops will apply this diagnosis fee to any required repairs if you have them perform the repairs for you. From there, a shop will be able to give you an accurate estimate for repairs to fix your P0141 code.
Can I drive with P0141?
You can drive the car normally and get it repaired at your earliest convenience. The trouble code that you are referring to, P0141, typically means that the heater element in an oxygen sensor is not functioning or the circuit to the heater element has a fault.
Where are heated oxygen sensors located?
The exhaust system has a Heated Oxygen Sensor in front of it. It is part of the Oxygen Sensor Heater. Behind the cylinder head is where the Heated Oxygen Sensor is located.
How much is a heated oxygen sensor?

How to fix p0141 code?
Clearing the fault codes and performing a road test to try and verify a failure
Which O2 sensor to replace first?
First check for exhaust leaks – that’s a common cause for an O2 sensor related codes. If that’s not it, follow the other guys’ advice and replace the appropriate O2 sensor (likely the post CAT sensor) first and see if that fixes the problem. If it doesn’t, move on to the cat. My money is on the O2 sensor or exhaust leak.
Which is the bank 1 for the O2 sensor?
Oxygen Sensor Bank 1 Sensor 1. The first one is located between the engine and catalytic converter, and we call it sensor 1 or an upstream sensor. It measures raw exhaust fumes’ composition, and the ECU uses this data to adjust the air-fuel mixture.
Where is the O2 sensor located?
Upstream oxygen sensors are located in between the engine and the catalytic converter
