P0575 code definition

The P0575 code indicates that the control input circuit is suffering from an electrical malfunction, as detected by the powertrain control module, or PCM.

What the P0575 code means

If the PCM detects an issue with the cruise control system, it will run a self-instituted test of the system. If there is an abnormal voltage/resistant result within the cruise control input circuit, it will store the OBD-II code P0575.

What causes the P0575 code?

The most likely cause of an abnormal voltage/resistance level in the cruise control input circuit is a faulty cruise control switch, particularly due to shorted circuitry caused by leaking or spilled liquids.

Other causes may include:

  • Shorted or open wiring
  • Open or shorted cruise control function switch harness
  • Damaged connectors within the cruise control system
  • Blown fuses, which may indicate a more serious issue

What are the symptoms of the P0575 code?

If the P0575 code is stored, it is likely that the cruise control has stopped working. In most cases, the Check Engine Light will illuminate within a few drive cycles after the PCM has detected the issue. While blown fuses can be a cause of this code being stored, they may also be a symptom of a larger issue.

How does a mechanic diagnose the P0575 code?

After verifying the P0575 code with an OBD-II scanner, a technician should begin with a visual inspection of all the wiring, connectors, and other components of the cruise control system. Any damaged elements should be replaced, reconnected, or repaired as necessary. They should then clear the code and perform a test drive, checking that the cruise control works as it should, and that the Check Engine Light does not reappear. If it does reappear, and the code has been stored in the PCM again, the mechanic has diagnosed a larger issue, and can begin more in-depth diagnostics and repairs.

Common mistakes when diagnosing the P0575 code

When diagnosing the underlying cause of the P0575 code, one of the most common mistakes made is to replace several components unnecessarily when the problem was actually a blown fuse. It’s important to check for blown fuses before replacing any components, and then to perform a retest to see if the fuse was causing the issue.

How serious is the P0575 code?

The P0575 code is only a mild issue that does not require immediate repair. The vehicle will still be operational, and the engine performance won’t suffer. The only issue that a driver would notice would be the inability to use cruise control. If an OBD-II scanner detects the P0575 code, and the vehicle is scheduled for a tune up soon, it is safe to wait until then to have the issue addressed.

What repairs can fix the P0575 code?

Repairing the issue behind a P0575 code may include a variety of fixes. They include:

  • Replacing a faulty cruise control switch.
  • Repairing any fluid leaks that caused the switch to malfunction.
  • Repairing or replacing shorted or open wiring.
  • Repairing or replacing open or shorted cruise control function switch harness.
  • Replacing damaged connectors within the cruise control system.
  • Replacing blown fuses. If blown fuses were the issue, the mechanic may wish to inspect the vehicle for additional problems.

Additional comments for consideration regarding the P0575 code

If a PCM displays an unresolved P0575 code, the vehicle may not be able to pass an emissions test. It is also very important to remember to clear the code after every repair, and to perform a retest. If this step is overlooked, it will mean that the mechanic won’t know exactly which repair fixed the issue, which means they may overlook a larger problem. By performing this step after every repair, it becomes easier to narrow down any reoccurring problems and address them.

Mister Ron was very nice and took time out to explain any concerns I might have about my car. He also made sure he communicated with me when he was on his way, once he was outside, and when we was done working on my car. I appreciate that considering I have a newborn that I had to look after.
