Guide To P2245 OBD Error Code Solutions

<<See All OBD Codes

Oftentimes, Engine Warning Light turns up almost immediately it senses the OBD code error. This directly impacts the engine performance as it struggles with power and acceleration as well as failed fuel system causing increased consumption of fuel by the engine.

An oxygen sensor for a particular engine bank that is not responding as per expectations, causes the PCM to store a trouble code and possibly illuminate the service engine soon light.

Oxygen sensors play an important role in the fuel, ignition timing, and valve timing strategies calculated by the PCM. The PCM collects information from various sensors around the engine to calculate the most suitable fuel/air ratio, ignition timing setting, as well as VVT/VCS settings to ensure that the engine delivers the optimal power with the best fuel economy.

If the PCM detects that it takes longer than about 60 seconds or so for the sensor element to heat up, or that the signal voltage does not move outside of the 390 to 490 millivolt range, it will deem the oxygen sensor to be inactive, set code P2245, and trigger the Check Engine Light.

What causes this problem with the O2 Sensor Reference Voltage Circuit Low Bank 1 Sensor 1?

• Damaged or Faulty heated oxygen sensor
• Electrical connector at the oxygen sensor can be damaged or disconnected
• Faulty or shorted wiring in the oxygen sensor circuit
• Connection error with sensors due to blown fuses
• Exponential variance in the fuel pressure
• Excessive exhaust leaks and vacuum leaks on the engine
• Damaged catalytic converter due to debris accumulation
• Faulty ECU (Engine Control Unit) picking up wrong data

1. Diesel Particulate Filter - The diesel particulate filter acts as an important component in managing the particulate emission in the exhaust system. If the filter is damaged, it may lead to increased emissions and pollutants through the tailpipe. Thus, replace damaged filter now!
2. Engine Control Module - It is not always the components, but the ECM that can also be faulty. It can cause misinterpretation of correct data thus leading to wrong operational decisions which will affect the transmission and overall engine performance. Thus, replace faulty module and reprogram it now!
3. Diesel Exhaust Fluid Heater - If the diesel exhaust fluid heater is faulty, it will not be able to aid in conversion of harmful nitrous oxide compounds to nitrogen, carbon dioxide and water vapours to control emissions. Thus, replace it immediately.
4. Exhaust System Parts - Your exhaust system begins at the engine with the purpose of removing toxic gases and fumes from your vehicle. The components are a series of pipes, catalytic converters, sensors, mufflers, and often a resonator, as well as other emission devices. Thus, replace damaged exhaust system now!
5. Powertrain Control Module - Powertrain Control Module can also be faulty in rare cases and thus needs through checks for system and software errors. Thus check and replace it, if required.
6. Electronic Control Unit - The ECU manages the cooling system to control the battery operating temperatures and thus must be replaced, if found faulty. Thus, buy new ECU modules and components from us!
7. Diagnostic Tool - Make use of quality diagnostic tools to resolve any OBD error code. Buy quality diagnostic tools from us!
8. Mass Air Flow Sensor - Wrong information sent by the sensor will affect the engine performance adversely as it will not be able to properly read the air entering the system thus hampering the air to fuel ratios directly impacting the engine’s output. Thus, it is advisable to replace them in time.
9. Manifold Absolute Pressure Sensor - If you are experiencing any problem with the pressure sensor, you should replace them immediately. Shop from us now!
10. Barometric Pressure Sensor - The BAP Sensor is used to measure the atmospheric pressure of the environment the engine is driving in. Thus, it plays a very important role in the engine’s performance. Replace the faulty BAP sensor now!
11. Fuel Injector - If there is a leakage in the fuel injectors, then it might cause rise in the fuel consumption, fuel odours around the vehicle and hard starting. You can always rely on us as we have best auto parts for our customers.
12. Fluid Pump - The fluid pump is usually located in the cover of the transmission. It draws fluid from a pump in the bottom of the transmission and feeds it to the hydraulic system. It also feeds the transmission cooler and the torque converter. Thus, replace faulty fluid pump now!
13. Heated Oxygen Sensor - The fault in the oxygen sensor leads to failure of the fuel delivery system, and engine control module. Replace faulty sensors immediately.

Willing to know some common symptoms of OBD Code P2245? Your wish is our demand. Have a look at them below:

Common Symptoms

• Significant decrease in the fuel economy
• Engine stalling and not starting along with loss of power and response
• Rough idle and hard starting of the engine
• Carbon deposit build up impacting the spark plugs
• Malfunction Indicator Lamp (MIL) illuminated

We have listed out so ways which would help you to correct the occurrence of OBD Code P2245. They are mentioned here as follows:

• Fuel pump replacement
• Fuel Filter replacement
• Exhaust System replacement
• Bad O2 sensor replacement
• Faulty wiring and connector issue
• PCM repair and reprogramming

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of Oxygen Sensor, PCM, ECM, Air/Fuel Sensor and many more. Now all your problems would vanish within no time.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

• Use a professional grade diagnostic scan tool to check for all codes present (must be used to show live sensor data).
• Observe and take note of any freeze frame data that is associated with the code along with the current collected data after the test drive.
• After the confirmation of P2245, clear the code and perform a test drive under the same circumstances shown in the freeze frame data.
• If the P2245 code returns, visual inspection is performed to check the integrity of the wiring and sensor.
• Scan with a tool used to monitor live data from Bank 1 Sensor 1 if the previous step is found to be okay.
• Check and test the ECM if the sensor checks out as under the rarest of chances it may be possible that ECM is faulty and needs replacement.

Common Mistakes When Diagnosing the P2245 Code

Never directly assume the Heated Oxygen Sensor is bad and needs replacement. The test procedure must be followed at all times to ensure that the wiring and other components are in good condition. Most of these problems are related to wiring touching the exhaust system. Always seek professional help to get the diagnosis as there might be many occasions where the diagnosis is much cheaper than perceived.
