P1382 Code: Meaning, Symptoms, Causes & Fix

Overview

Code P1382 indicates a fault in Variable Cam Timing Solenoid #1 Circuit Malfunction, typically within engine synchronization and valve timing.

Symptoms

engine noise or unstable timing
loss of power at mid/high RPM
hard start when cold

Common causes

Disconnected or loose connector affecting variable cam timing solenoid #1 circuit malfunction
Broken terminal inside harness
Connector pin damage/corrosion or harness stress near related components

How to diagnose P1382

Confirm P1382 and capture freeze-frame data with a professional scan tool.
Inspect wiring, connectors, and grounds related to variable cam timing solenoid #1 circuit malfunction 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 P1382

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

Can you drive with P1382?

Most vehicles can be driven short-term with P1382, 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 variable cam timing solenoid #1 circuit malfunction circuit/system.
Apply the required relearn/adaptation procedure if specified by service information.
Road-test and verify P1382 remains cleared under the conditions that originally set the code.

Fix options

Repair open circuit and secure connector lock.
Restore continuity and verify pin tension.
Clear DTCs and verify with live data and completed drive cycle.

Typical repair cost

$300-$1400

Common mistakes when diagnosing P1382

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.

P1382 in common vehicles

P1382 appears across makes such as Mazda, Subaru, Lexus, Jeep. Failure patterns differ by platform: wiring routes, software calibration, and component supplier revisions can change root cause.

Frequently asked questions

What causes P1382?

P1382 is commonly set by open faults affecting variable cam timing solenoid #1 circuit malfunction.

How much does it cost to fix P1382?

For P1382, repair costs are typically $300-$1400 depending on exact root cause, labor rates, and part quality.

Can I clear P1382 without repair?

You can clear P1382 temporarily, but the code usually returns until the underlying fault is corrected.
