P0562 Code: Meaning, Symptoms, Causes & Fix

Overview

Code P0562 indicates a fault in System Voltage Low, typically within powertrain controls.

Symptoms

rough operation in certain conditions
check engine light
increased fuel use

Common causes

High circuit resistance affecting system voltage low
Sensor output out of expected lower range
Connector pin damage/corrosion or harness stress near related components

How to diagnose P0562

Confirm P0562 and capture freeze-frame data with a professional scan tool.
Inspect wiring, connectors, and grounds related to system voltage low for obvious defects.
Compare live data against expected lower threshold and verify ground/reference circuits.
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 P0562

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

Can you drive with P0562?

Most vehicles can be driven short-term with P0562, 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 (low) in the system voltage low circuit/system.
Apply the required relearn/adaptation procedure if specified by service information.
Road-test and verify P0562 remains cleared under the conditions that originally set the code.

Fix options

Verify ground path and signal integrity.
Repair connector resistance issues.
Clear DTCs and verify with live data and completed drive cycle.

Typical repair cost

$200-$900

Common mistakes when diagnosing P0562

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.

P0562 in common vehicles

P0562 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 P0562?

P0562 is commonly set by low faults affecting system voltage low.

How much does it cost to fix P0562?

For P0562, repair costs are typically $200-$900 depending on exact root cause, labor rates, and part quality.

Can I clear P0562 without repair?

You can clear P0562 temporarily, but the code usually returns until the underlying fault is corrected.
