What causes P0161 code?

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.

Which side is bank 2 02 sensor?

On Bank 2 means it is at the engine side with cylinders 2, 4, 6, 8, etc. Bank 2 Sensor 2 is the second sensor on the engine’s exhaust pipe, usually behind the catalytic converter. On Bank 2 means it is at the engine side with cylinders 2, 4, 6, 8, etc.

Where is oxygen sensor bank 2 located?

A vehicle’s (bank 2, sensor 2) O2 sensor will be located behind or downstream of the catalytic converter on the bank which corresponds to the engine’s second cylinder.

Which side of a vehicle is bank 2?

It would be presumptive to simply say it is found on the passenger side (although this is predominantly true for rear-wheel drive). By definition, Bank 2 refers to the side of an engine with the cylinder firing orders 2, 4, 6, 8, 10, and 12. It is the opposite of the B1S1 (Bank 1 Sensor 1) location.

What is a bank 1 O2 sensor?

It is the sensor that measures the oxygen content in the exhaust, providing an input to the computer, which determines how to adjust the air/fuel ratio.

What side is bank 2 on a Jeep?

passenger side

How many O2 sensors does a Jeep Grand Cherokee have?

Two sensors are used: upstream (referred to as 1/1) and downstream (referred to as 1/2). With this emission package, the upstream sensor (1/1) is located just before the main catalytic convertor. The downstream sensor (1/2) is located just after the main catalytic convertor.
