P0145 OBD Error Code: Problem & Solutions

<<See All OBD Codes

If you are having a defective O2 sensor, then chances are that you develop OBD error code P0145. This error code means that the post catalytic converter Oxygen sensor is either slow or unresponsive. So, that might pose a serious problem to your vehicle. We suggest you to fix at the earliest. To be able to do so, you need to understand this problem in depth.

Just like error code P0144, P0145 is also a generic OBD-II error code meaning that your vehicle’s O2 sensor for bank 1 sensor 3 has failed. It has a voltage lower than .2 volts peer 7 seconds. So, your ECM will detect that the sensor response is too slow or unresponsive. It will start flashing this OBD Error Code P0145. Wondering what causes this problem? Have a look at the below listed points.

What causes this problem with the O2 sensor circuit slow response (Bank 1 Sensor 3)?

• Leaking fuel injector
• Damaged or defective oxygen sensor
• Exhaust leakage
• Defective engine wiring or connector
• Catalytic converter issues such as clogging

It is extremely important to know the symptoms of a problem; therefore, we have listed out few common symptoms of OBD error code for you. There might not be many abnormal symptoms to notice.

Common Symptoms

• Illumination of check engine light
• Emission test failure
• Exhaust emissions
• Fall in engine efficiency
• Fall in fuel efficiency

If you wish to correct this problem with your vehicle then apart from understanding its common causes and symptoms, you also need to understand and follow these following steps:

• First of all, you will need to conduct fuel and exhaust system tests.
• After you discover that the tests stand okay, then you will need to replace the oxygen sensor for bank 1 sensor 3, as it might be faulty.
• You will also need to repair any oil or coolant leakage to prevent it from leaking into the sensor
• Also undergo a fuel injector or fuel regulator replacement, if found faulty.
• Before replacing the fuel injector, you can also try cleaning it to see if the leaks stop.

 If you wish to correct this problem on your own, then you will need few essential parts and tools. You can get them all with us at best prices and also from top brands like Raybestos, Various Manufacturers, Beck/Arnley and many more.

To conduct a proper diagnosis for OBD error code P0145, you will need to undergo specific steps as listed below:

• Firstly, get an OBD scanner to scan the code and freeze the data for the oxygen sensor
• Now monitor the oxygen sensor to check if its voltage drops below to .2 volts amid the deceleration for all the o2 sensors.
• After that check the fuel infusion framework for spilling injectors in case all the O2 sensors show voltages over .2 volts on deceleration
• Next, check the engine fuel pressure for a spilling fuel injector or fuel pressure regulator
• After that conduct a test to check O2 sensor for contaminations with coolant or oil
• Next you will need to check the O2 sensor harness for any sort of water tainting
• Lastly, for further diagnosis you will need to undertake manufacturer's specific tests.

Common Mistakes When Diagnosing The P0145 Code

To avoid any misdiagnosis, follow the following steps:

• Before replacing the oxygen sensor, make sure you check the complete fuel system for any damage.
• Also make sure that you check the fuel injection system too for any sort of leakage.
• Also, do check fuel pressure regulator to see if it is fouled.
• Lastly before you install a new sensor make sure you repair oil or coolant leaks into the O2 sensor.
