Code P0161 occurs when the powertrain control module tests the downstream heated oxygen sensor’s heater circuit on Bank 2 and detects a short in the circuit or excessive resistance in the heater circuit.
How do I fix error code P0161?
What repairs can fix the P0161 code?
- Replacement of the bank 2 sensor 2 oxygen sensor.
- Repairing the wiring in the heater circuit.
What does engine code P0161 mean?
Code P0161 sets when the Powertrain Computer or PCM has determined that the Oxygen Sensor Heating Circuit is malfunctioning. This means that the Heating Circuit is using too little or too much electrical power.
Where is the O2 sensor heater 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.
What O2 sensor is bank 2 sensor 2?
Diagnostic Trouble Code (DTC) P0158 stands for O2 Sensor Circuit High Voltage (Bank 2, Sensor 2). The O2 sensor 2 is the downstream O2 sensor and it measures the amount of oxygen in the exhaust gases leaving the catalytic converter (cat).
Can you drive with a P0161 code?
What Does Code P0161 Mean? Issue Severity: MODERATE– Extended driving with this code can cause internal engine damage. Repair Urgency: Get this code fixed as soon as possible.
What does heater circuit malfunction 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.
What is the code for a bad O2 sensor?
Once the oxygen sensor stops performing as intended, the vehicle computer detects that and turns on the Check Engine light. This will usually have a diagnostic trouble code (DTC) of P0138. Typically, you’d take the vehicle into the shop, where they’d diagnose the issue and replace the oxygen sensor for you.
