Fault code po470

Here are the fault codes you provided for a 2015 International 4700 with a Cummins 6.7 engine:
1. Fault Code 4094: This fault code refers to "Selective Catalyst Reduction (SCR) Catalyst Conversion Efficiency - Data Valid but Below Normal Operating Range - Moderately Severe Level." It indicates an issue with the SCR system's efficiency. This could be caused by a malfunctioning SCR catalyst, a faulty sensor, or an exhaust leak. Professional diagnosis and repair are recommended to address this fault.
2. Fault Code 1569: This code indicates "Crankcase Breather Filter Restriction - Condition Exists." It means there is a restriction in the crankcase breather filter. Check the breather filter and replace it if necessary. Cleaning or replacing the crankcase breather assembly might also be required.
3. Fault Code 1552: This fault code refers to "Fuel Rail Pressure Too Low - Moderate Severity." It suggests that the fuel rail pressure is lower than the expected range. Potential causes could include a clogged fuel filter, a faulty fuel pump, a fuel pressure sensor issue, or a problem with the fuel injectors. A thorough inspection and diagnostic testing should be performed to identify the exact cause and resolve the issue.
4. Fault Code 597: This code indicates "Injector Power Supply - Bad Intelligent Device or Component." It means there is a problem with the injector power supply. Possible causes include a faulty injector, a wiring issue, or a problem with the engine control module (ECM). A professional diagnosis is necessary to determine the precise cause and undertake appropriate repairs.
5. Fault Code 790: This fault code refers to "Engine Overspeed Warning - Critical Level." It indicates that the engine speed has exceeded the recommended maximum limit. This can occur due to driver error, a faulty sensor, or a malfunctioning ECM. It is crucial to investigate the cause of the overspeed condition and rectify it promptly to prevent engine damage.
Please note that these fault codes provide a general indication of the potential issues, but a comprehensive diagnosis by a qualified technician with access to the appropriate diagnostic tools is necessary for accurate identification and repair.

DTC ) fault code ) - P1237:
Boost Control Positive Deviation

This fault code can be set when the fuel tank is empty or the specified fuel is not used. ( supermarket fuels etc have been known to cause this.. )

It can also be attributed to a turbo fault - if the fault is no turbo boost.

Clearing the codes is simple that is done by removing the fuse of the EFI from junction box 2 for 10 seconds. Make sure to remove the jumper wire and switch the key off before clearing the codes.

According to the experience in the repair, fault code P0171 is used in the fuel system, such as a fuel injector or fuel filter clogging, fuel pressure problems.
The fuel adjustment values measured by GM TECH2, Fault code P0171 is Buick car of a multiple fault. Fault car most can be cleaned by the injector, replacing the fuel filter troubleshooting, also have individual vehicle is to solve the problem by replacing the air flow meter.

O.b.d. .ll trouble code exhaust pressure malfunction

very Unlikely this will have any affect. sounds more like an air leak to me.
You will find all codes available at http://www.bluejag.co.uk/decode.php



Fault Code:- P0171 Indicates a Power-train fault
