Error Code P0160: What It Means & What To Do?

<<See All OBD Codes

The P0160 fault code can be defined as Oe sensor circuit no activity detected bank 2 sensor 2. This code would generally trigger when there is no activity detected on the bank 2 sensor 2 of the oxygen sensor circuit. This would happen when the voltage signal sent from the sensor to the powertrain control module which is constant, meaning there is a fault in the circuit.

The trouble code P0160 is the code for post catalyst O2 sensor is not functioning properly or is not operating at all. The main role of the catalytic converter is to control emissions. The oxygen sensor at bank 2 position 2 is after the converter on bank 2, and would check the efficiency of the catalytic converter on that bank.

What causes this problem with the 02 Sensor Circuit No Activity Detected (Bank 2 Sensor 2)?

• A wire that is broken or disconnected from the oxygen sensor
• Issue of corrosion in the connectors
• There can be a leakage in the engine vacuum
• Defects in the power control module

1. Oxygen Sensor - Are you facing OBD Error Code P0160? Don’t worry as you can fix this issue with new Oxygen Sensor. We care for our customers, that’s why we have Oxygen Sensor for every make and model.
2. Mass Air Flow sensor - A broken Mass Air Flow sensor can cause a lot of issues. It would be nice if you get it replaced on time.
3. Manifold Absolute Pressure sensor - The P0160 code can also arise due to some issues in Manifold Absolute Pressure sensor. So, it is advised to replace them as soon as possible.
4. Exhaust Parts - There can be some issues with the Exhaust Parts due to which you may see P0160 code appearing over and over again. Visit us to buy best quality Exhaust Parts online.
5. Powertrain Control Module - A lot of issues can arise do to defective Powertrain Control Module. Did you just see P0160 code flashing? Now you know the reason why it is appearing. Get it inspected and replaced on time.
6. Engine Control Module - Faulty Engine Control Module can be the reason why P0160 code is flashing. Visit us to purchase top notch Engine Control Module online.
7. Fuel Pump - It is an important auto part which needs full care. A faulty Fuel Pump can be a reason behind the flashing up of P0160 code.

You might be thinking that how would you diagnose these problems? We at Parts Avatar Canada would help you diagnose the major symptoms easily.

Common Symptoms:

• There can be an illumination in the check engine light on the dashboard may come on and the car engine might start stalling
• The car driver might experience the feeling that the car is running rough or that it is idling poorly
• A smell which is similar to rotten eggs can start coming or can see black smoke billowing from the exhaust
• There can be times when a driver will not notice any of these symptoms, other than the check engine light appearing, but this is a very rare case

If you want to validate the fault code, then an OBD scanner should be used. After the fault code has been validated, it should be reset and take your vehicle out for a test drive. If the check engine light returns with the same fault code, then you must do an inspection

• The other step is to inspect the wires and connectors for any damage. If the wires and connectors are damaged, they should be repaired or replaced. Then you must reset the fault code and test drive your vehicle
• If you find that the check engine light is coming on again and the technician gets the same code, the, you must replace the oxygen sensor
• If you find out that the P0160 trouble code is still appearing back after replacing the oxygen sensor, the exhaust pipe and heater fuse should be inspected to rule out possible damage of the two

Parts Avatar Canada is here to solve all your issues related to car parts. We have stocked a wide range of best priced battery connectors, connect amp, air flow meter and a lot more to help you out in fixing your car.

• An OBD-II scanner should be used by the technician to diagnose the P0160 code. The freeze frame data should be captured in order to determine when the code was first set. At this point, the code should be reset and the vehicle should be taken out for a test drive
• Now while test driving, the vehicle should reach to the normal operating temperature in order to see if the code comes back. If the fault code does come back, then you must inspect the wiring that goes to the oxygen sensor and grounds. During the inspection the technician will look for breaks and corrosion. Live data should be observed in an effort to determine whether the millivolt valves are going low to high
• You must inspect the oxygen sensor in order to determine whether it has power going to it and that it is receiving the proper signal voltage from the powertrain control module

Common Mistakes When Diagnosing The P0160 Code

• One of the most common mistakes which a lot of people make is to replace the car oxygen sensor without actually performing any diagnostics and then still facing the problem
• The other common problem can be replacing the wrong sensor. It all depends upon the engine configuration it is possible to get the cylinder banks confused if you do not actually consult the service information for the vehicle on which you are working
