P0365 – Camshaft Position Sensor B Circuit (Bank 2): Symptoms, Causes, Diagnosis & Repair Cost (2026 Guide)

P0365

Last updated:

Overview

The control module stored P0365 because it detected a problem with: Camshaft Position Sensor B Circuit (Bank 2).

P0365 relates to Camshaft Position Sensor B Circuit (Bank 2). Use a quality scan tool, follow wiring diagrams for your vehicle, and confirm tests before replacing expensive parts.

What does the P0365 code mean?

When P0365 is set, the vehicle’s diagnostics detected an issue described as: Camshaft Position Sensor B Circuit (Bank 2). In practice, the ECM/PCM (and related modules) compare sensor inputs, commanded outputs, and self-tests for that subsystem. The exact repair depends on whether the fault is wiring-related, component-related, or a rationality/performance issue for this circuit or system.

Common symptoms of P0365

  • Extended crank
  • Rough running or misfire feel
  • Loss of power
  • Unusual engine noise
  • Check engine light
  • Hard start

Possible causes

  • Fault affecting Camshaft Position Sensor B Circuit (Bank 2) (wiring, connector, or component)
  • Component failure in the described system
  • Electrical fault in the monitored circuit
  • Control module strategy or calibration issue
  • Control module or software calibration issue (less common—verify tests first)
  • Past repairs or aftermarket parts causing out-of-spec operation

How to diagnose P0365

  1. Scan for P0365 and review freeze frame / pending codes for related faults
  2. Inspect connectors and wiring related to: Camshaft Position Sensor B Circuit (Bank 2)
  3. Compare live data and commanded vs actual values for the affected system (per service information)
  4. Perform circuit tests appropriate to the fault type (continuity, voltage, resistance) before replacing parts
  5. Confirm power and ground integrity at the relevant module or sensor
  6. After repair, clear DTCs and verify under the conditions that originally set P0365

Tip: Use a scan tool that shows live data and freeze frame for the conditions when the code set.

Severity of code P0365

High: This fault can impact safety-related systems or core drivability—prioritize professional diagnosis.

Can you drive with P0365?

Short trips may be okay if the vehicle feels normal, but have it diagnosed—especially if performance, safety warnings, or overheating are present.

Avoid heavy acceleration, towing, or long highway drives until the cause of P0365 is confirmed and repaired.

How to fix it (step-by-step)

  1. Start with visual inspection and connector cleaning/tightening where needed
  2. Confirm failure mode with testing—avoid swapping parts without evidence
  3. Repair wiring or replace the failed component per manufacturer procedure
  4. Clear faults, run relearns if required, and road test to confirm

Repair & fix options

  • Clear codes and verify with drive cycle
  • Inspect connectors and wiring first
  • Test component against service limits
  • Clear codes and verify repair with a drive cycle and readiness where applicable
  • Reinspect related monitors if the code returns after repair

Typical repair cost

$120 – $3,500+ depending on cause

Estimated cost breakdown for P0365
Repair type Typical range
Diagnostic And Minor $180 – $900
Common Component Work $800 – $3,500+
Major Subsystem Repair $400 – $1,800
Severe Or Replacement $120 – $1,200

How to help prevent P0365 in the future

  • Fix new codes early before secondary damage or catalyst stress
  • Keep connectors clean and secure; address rodent or water intrusion in harnesses
  • Use the correct fluids/parts for your vehicle and service intervals
  • Avoid ignoring pending codes after battery work or repairs

When to see a mechanic

Schedule diagnosis if the check engine light is on, drivability is worse, or you notice new noises, smells, or warning lamps. For safety-related (SRS/ABS) or overheating symptoms, prioritize a qualified shop immediately.

Common mistakes when diagnosing P0365

  • Replacing sensors/modules without verifying wiring and reference voltages
  • Ignoring related codes that identify the real root cause
  • Clearing codes without a verification drive cycle

Common vehicles & notes for P0365

  • Nissan / Hyundai models (common examples—verify for your vehicle)
  • Kia / Mazda applications vary by engine and model year
  • Many other makes—this is a standardized OBD-II definition: Camshaft Position Sensor B Circuit (Bank 2)

P0365 is reported across many platforms including Nissan, Hyundai, Kia, Mazda. Always use VIN-specific service information for testing limits and calibration steps.

Frequently asked questions

What does P0365 mean?

P0365 indicates a fault involving Camshaft Position Sensor B Circuit (Bank 2), based on what the control module detected during self-tests or live monitoring.

Is it safe to drive with P0365?

If the vehicle runs normally and no warning lights are flashing, short trips may be reasonable—but avoid ignoring symptoms like misfire, overheating, ABS/SRS warnings, or major loss of power.

How much does it cost to fix P0365?

Typical repairs often fall in the ranges shown on this page, but final cost depends on labor rate, parts quality, and whether the issue is wiring vs. a major component.

What is the most common cause of P0365?

Most shops start with wiring/connectors and the directly monitored component for “Camshaft Position Sensor B Circuit (Bank 2),” then expand testing if the fault returns.

Will P0365 clear itself?

It may become intermittent, but if the underlying fault remains, the code will usually return—especially after a drive cycle.

Can a weak battery cause P0365?

Low system voltage can cause odd sensor/module behavior, but you should still validate the actual DTC and perform normal circuit/component tests.
