P0364 medium Severity

P0364: Camshaft Position Sensor B Circuit Range/Performance (Bank 1)

Possible rough idle, reduced power, intermittent stalls, poor fuel economy

Overview

P0364 indicates an OBD-II camshaft position sensor 'B' circuit range/performance fault on Bank 1, typically due to sensor signal irregularity, wiring faults, or timing issues.

Common Symptoms

  • Check Engine Light illuminated
  • Engine performance irregular or reduced power
  • Poor fuel economy
  • Rough idle or intermittent stalling
  • Difficulty starting

Most Common Causes

Faulty camshaft position sensor B high

Sensor failing to produce correct signal leads to range/performance fault.

Wiring issues (open, short, corrosion) high

Circuit integrity issues often cause intermittent signal triggering the code.

Poor electrical connection at connector medium

Loose or corroded connectors can degrade signal quality.

Timing chain/belt alignment issue medium

Incorrect mechanical timing affects camshaft sensor signal accuracy.

ECM misinterpretation or rare module fault low

Less common, requires module reflash or replacement if confirmed.

Diagnostic Steps

  1. Use a professional OBD-II scanner to confirm P0364 and check freeze frame data
    Expected: P0364 present, possibly with other camshaft-related codes
    Interpretation: Verifies current fault and captures conditions under which it occurred.
  2. Visually inspect camshaft position sensor B and its wiring harness/connectors
    Expected: No broken wires, corrosion, or loose pins
    Interpretation: Detects obvious circuit integrity issues.
  3. Measure sensor signal voltage and resistance with a multimeter/oscilloscope
    Expected: Signal within manufacturer spec and consistent pattern
    Interpretation: Confirms proper sensor output; abnormal readings indicate sensor/circuit fault.
  4. Check engine mechanical timing (timing belt/chain alignment)
    Expected: Correct alignment according to service manual
    Interpretation: Misalignment can cause cam signal timing irregularities seen as a P0364.
  5. Clear codes, test drive, and monitor live data
    Expected: No recurrence of P0364
    Interpretation: Verifies repair success and confirms fault was resolved.

Repair Solutions

Replace camshaft position sensor B medium
Estimated Cost: $50 - $350

Includes part and labor; cost depends on vehicle and accessibility.

Repair or replace damaged wiring/connectors medium
Estimated Cost: $20 - $200

Depends on extent of wiring issues and labor.

Correct timing chain/belt alignment hard
Estimated Cost: $300 - $1200

Variable timing component service can be labor intensive.

ECM reprogram or replacement hard
Estimated Cost: $150 - $1500

Only if confirmed via advanced diagnostics; rare.

Common Misdiagnoses

Avoid these common diagnostic mistakes:

  • Confusion with DC/AC converter control module codes or incorrect assignment from generic scan tools
