P0575 Code: Meaning, Symptoms, Causes & Fix

Overview

P0575 is triggered when monitoring logic identifies an issue with Cruise Control Input Circuit affecting powertrain controls.

Symptoms

rough operation in certain conditions
check engine light
increased fuel use

Common causes

Open circuit in wiring affecting cruise control input circuit
Disconnected or loose connector
Connector pin damage/corrosion or harness stress near related components

How to diagnose P0575

Confirm P0575 and capture freeze-frame data with a professional scan tool.
Inspect wiring, connectors, and grounds related to cruise control input circuit for obvious defects.
Use a continuity test from module pin to component to identify opens/high resistance.
Check for related DTCs to identify the root-cause chain before replacing parts.
After repair, clear codes and confirm readiness monitors complete without recurrence.

Severity of code P0575

Moderate: This code is moderate severity: the vehicle may still operate, but fault progression can increase repair cost over time.

Can you drive with P0575?

Most vehicles can be driven short-term with P0575, but postpone heavy load/highway driving until repaired.

If the warning lamp is flashing or drivability/safety is affected, avoid driving and diagnose immediately.

How to fix it (step-by-step)

Repair obvious wiring/connector faults first to prevent repeat parts replacement.
Address the root fault mode (open) in the cruise control input circuit circuit/system.
Apply the required relearn/adaptation procedure if specified by service information.
Road-test and verify P0575 remains cleared under the conditions that originally set the code.

Fix options

Repair open circuit and secure connector lock.
Clear corrosion and protect terminals.
Clear DTCs and verify with live data and completed drive cycle.

Typical repair cost

$200-$900

Common mistakes when diagnosing P0575

Replacing parts without verifying voltage, ground, and signal integrity first.
Ignoring related stored/pending codes that indicate upstream faults.
Skipping post-repair verification drive cycle and readiness checks.

P0575 in common vehicles

P0575 appears across makes such as Nissan, Hyundai, Kia, Volkswagen. Failure patterns differ by platform: wiring routes, software calibration, and component supplier revisions can change root cause.

Frequently asked questions

What causes P0575?

P0575 is commonly set by open faults affecting cruise control input circuit.

How much does it cost to fix P0575?

For P0575, repair costs are typically $200-$900 depending on exact root cause, labor rates, and part quality.

Can I clear P0575 without repair?

You can clear P0575 temporarily, but the code usually returns until the underlying fault is corrected.
