Description Icon Long Description

Fault code P1497 is a manufacturer-specific code that indicates that the powertrain control module (PCM) has detected an issue with the exhaust gas recirculation (EGR) valve stepper motor 2.

The EGR system allows for the recirculation of the exhaust gasses back into the engine to improve the efficiency of the engine and reduce the number of emissions put into the atmosphere.

This is because there is a portion of unburnt fuel products that can be reused, rather than expelled from the exhaust.

The stepper motor takes inputs from the control module and uses them to control the opening and closing of the EGR valve.

Despite being a manufacturer-specific code, it represents the same or very similar issues for a number of notable manufacturers. This includes Mazda, Mercedes-Benz, Ford, and Subaru. All of these manufacturers indicate that there is an electrical fault at work in the stepper motor circuit.

Warnings Icon Other Signs of This Problem

The EGR system does not have a huge impact on the driveability or performance of the vehicle as a whole. This can mean that this fault code will not always be accompanied by noticeable symptoms. However, there may be some in certain cases like if the valve is stuck open.

One of the most common signs will be the presence of the Check Engine light on the dashboard.

In some cases, it may be possible that the engine runs rough. This can include stalling and misfires, but this is very rare.

It is also possible that there will be similar generic fault codes logged. These can range from P0400 to P0405. Fault code P0403 is potentially the most similar generic version of this code.

Broken Down Icon What Could Be The Problem?

In most cases, these types of fault codes will have the same fairly common causes.

These will typically include a faulty EGR valve. This can be the result of a defective stepper motor. It is also possible that the valve and its passages are filled with carbon build-up.

In addition to this, the stepper motor circuit could be the source of the issue. There may be electrical faults like damaged wires or loose connections that prevent the stepper motor from functioning properly.

While unlikely, it is possible that there is an issue with the PCM. This will typically be accompanied by a number of additional fault codes, though.

Fixed Icon Fixes

Fixing this issue can require replacing faulty mechanical parts or making repairs to electrical faults in the relevant EGR circuits.

The first thing to check is the EGR valve stepper motor itself. If it is defective, it needs to be replaced.

Similarly, the stepper motor circuit needs to be checked for open or short circuits. If any issues are found, they must be fixed.

The EGR valve may need to be replaced altogether if it is faulty. If the EGR valve or passages are simply dirty, they should be cleaned.

If there is an issue with the PCM, it may need to be replaced.

Danger Icon Seriousness

Fault code P1497 is a moderately serious issue, depending on the symptoms present. Typically, it does not pose many issues to the performance of the vehicle or its safe operation but in rare cases, its symptoms can be harmful to the engine.

It is a good idea to have this issue fixed depending on your specific case. Cases with more severe symptoms should be fixed as soon as possible.
