P0335 Code: Meaning, Symptoms, Causes & Fix

Overview

Code P0335 indicates a fault in Crankshaft Position Sensor A Circuit Malfunction, typically within engine synchronization and valve timing.

Symptoms

hard start when cold
rough running or misfire
engine noise or unstable timing

Common causes

Disconnected or loose connector affecting crankshaft position sensor a circuit malfunction
Broken terminal inside harness
Connector pin damage/corrosion or harness stress near related components

How to diagnose P0335

Confirm P0335 and capture freeze-frame data with a professional scan tool.
Inspect wiring, connectors, and grounds related to crankshaft position sensor a 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 P0335

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

Can you drive with P0335?

Most vehicles can be driven short-term with P0335, 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 crankshaft position sensor a circuit malfunction circuit/system.
Apply the required relearn/adaptation procedure if specified by service information.
Road-test and verify P0335 remains cleared under the conditions that originally set the code.

Fix options

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

Typical repair cost

$300-$1400

Common mistakes when diagnosing P0335

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.

P0335 in common vehicles

P0335 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 P0335?

P0335 is commonly set by open faults affecting crankshaft position sensor a circuit malfunction.

How much does it cost to fix P0335?

For P0335, repair costs are typically $300-$1400 depending on exact root cause, labor rates, and part quality.

Can I clear P0335 without repair?

You can clear P0335 temporarily, but the code usually returns until the underlying fault is corrected.
