The P0160 code indicates that the Engine Control Module (ECM) has detected an issue with the oxygen sensor circuit for Bank 2 Sensor 2. This typically means that the sensor is either not functioning properly, or there is a fault in the wiring or connections leading to the sensor. Oxygen sensors play a critical role in monitoring the amount of oxygen in the exhaust gases, which is essential for optimal fuel efficiency and emissions control.

What are the symptoms of the P0160 code?

• Check Engine Light (CEL) illuminated
• Poor fuel economy
• Rough engine idle
• Increased emissions
• Failed emissions test

What causes the P0160 code?

• Faulty oxygen sensor (Bank 2 Sensor 2)
• Damaged wiring or connectors related to the sensor
• Exhaust leaks near the sensor location
• Issues with the Engine Control Module (ECM)
• Corrosion or poor connections at the sensor terminals

How to fix P0160?

• Inspect and test the oxygen sensor for proper operation.
• Check wiring and connectors for damage or corrosion.
• Repair or replace damaged connectors or wiring as needed.
• If the oxygen sensor is faulty, replace it with a new one.
• Clear the fault codes and retest the vehicle to ensure the problem has been resolved.
