Error Code P207F: What It Means & What To Do?

<<See All OBD Codes

If the Check Engine Light illuminating on the dashboard? Are you experiencing reduced engine performance along with affected fuel economy? Is there black smoke emitting from the exhaust pipe? All these are the indications of increased emissions and affected exhaust system which in this case can be due to bad reductant performance, thus causing OBD code P207F to get stored in the Powertrain Control Module.

Usually, this type of error code gets stored in the system when the PCM notes that the reductant performance is down. This can be due to various mechanical faults in various related components. When the error occurs due to erratic functioning of the reductant pump thus resulting in increased emissions, the OBD code P207F gets stored in the PCM.

What causes this problem with the Reductant Quality Performance?

• Bad Reductant pump
• Wiring and harness for Reductant pump circuit is open or short
• Poor electrical connections to Reductant pump circuit
• SCR controller/PCM or programming error

1. Powertrain Control Module – Faulty PCM can cause performance issues due to problem with the fuel delivery and transmission issues as well as the starting and charging system and can also store wrong OBD code leading to misdiagnosis. Replace it now!
2. Engine Control Module - Is your car engine light still staying ON after resetting or your car engine is turning off for no reason? Then these are some common symptoms indicating that your car engine control module is defective.
3. Electronic Control Unit – The ECU is a major component of your car's on board computer. It's used to regulate many systems and subsystems in your car's engine, drive train and other major components. Visit us to buy best quality ECU online.
4. Diagnostic Tools - Take help of a professional mechanic to diagnose OBD code error. Use high grade diagnostic tools to resolve this issue. Buy new tools and equipment form us!
5. Exhaust Gas Recirculation Valve - Did you just see check engine light flashing on your dashboard? If the computer would detect some fault with the automobile’s EGR valve circuit, then it would set up the check engine light so that the driver is notified about the fault. Don’t waste time and get them replaced or else this fault code can turn up.
6. Diesel Exhaust Fluid Pump - The diesel exhaust fluid pump needs to work properly if the transmission system has to perform. If it is not functioning, the transmission may slip and cause harsh shifts too. Thus replace faulty pump now and buy a new one from us!
   

We care for our customers and that’s why we can totally understand your problem. That’s the reason why we have listed out some major symptoms behind the flashing up of OBD Code P207F. They are mentioned here as follows:

Common Symptoms

• Check engine light can start flashing up
• Affected fuel economy
• Reduced Engine performance
• Sometimes there might be no visible symptoms present
• Black smoke might start emitting from the tailpipe during acceleration

Here are some ways with the help of which you will be able to correct the OBD Code P207F.

• Repair or replace the loose, broken or corroded wiring
• Rehabilitate the defaults in the reduction pump circuit
• You must fix the defective or corroded connectors
• Make sure to mend the faulty exhaust system parts
• Carefully adjust the faults in the exhaust gas temperature sensor (EGTS)
• Recondition the non-functioning terminals

Do you wish to diagnose P207F error code easily? Here are some steps which you should follow in order to diagnose this fault code:

• Initial step is to visually examine the wiring for faults, frays, or wires that have melted.
• Visually inspect the connector for damage, frays, or corrosion. Make sure to mend the defective wiring or connectors as per the requirement.
• The mechanic should retest the system to make sure that the wiring and connectors are in good working condition.
• The mechanic or the technician will use a diagnostic scanner or code reader like DVOM to visually scan for the error codes in the vehicle.
• After performing a careful inspection, every of the stored codes and freeze frame data are retrieved as itcan help down the way for further diagnosis process.
• He will know that an intermittent condition persists, if the code does not return instantly.
• Intermittent conditions are very tough to diagnose, and they need time to get worse before they can be diagnosed correctly.
• Check the circuitry of the exhaust gas temperature sensor EGTS)/exhaust gas pressure sensor (EGPS) near where the hot exhaust constituents are close to wiring and connectors.
• Rehabilitate the defaults in the circuitry. The entire system should be retested to make sure that the circuitry of the exhaust gas temperature sensor and pressure sensor are in good working condition.
• After that it is essential to examine the resistance of the EGTS/EGPS. The specifications of the resistance are decided by the manufacturer, but are typically 150 ohms. A resistance reading of below 50 ohms would indicate that there is need to replace the defective sensor.
• A heating component should be used to examine the resistance with the volt/ohmmeter. The level of the resistance would decline when the heating component is added and would rise when the sensor would cool.
• If this would not happen, then it would indicate that there is a need to restore the faulty EGTS/ EGPS.
• The voltage of the EGTS /EGPS, at the electrical connector should be checked properly. Keep in mind that the reading of the voltage should be at 5-volts.
• Now if the voltage reading of the EGTS/EGPS would not be at 5-volts, then you should inspect the continuity between the PCM and the signal wire.
• There would be a need to replace or reprogram the PCM if there is continuity.
• There might be some flaws in the reductant injection air controller if no voltage is present on the sensor connector.
• If the mechanic finds out that there is no voltage present in the sensor connector, then it would that there are some quirks in it. Reprogram the defective reductant injection air controller.
• The P207F trouble code would start appearing due to problematic reductant pump circuit that might need immediate repair or replacement. Thus, optimal replacements are in order.

Common Mistakes When Diagnosing The P207F Code

• Sometimes the mechanic might not know the difference between the oxygen sensor for the reductant injection pressure sensor as both of them look same and he might replace the wrong sensor, giving rise to more problems
• Reductant pump circuit damaged or open
• Most mechanics simply neglect to examine the wiring, connectors and terminals for damage
