P0336 medium Severity

P0336: Crankshaft Position Sensor "A" Circuit Range/Performance

Engine may hesitate, stall, have difficulty starting, or fail to start due to improper crank signal affecting ignition timing and fuel delivery

Overview

Crankshaft Position Sensor A Circuit Range/Performance DTC P0336 with causes, symptoms, diagnostics, and repair interventions

Common Symptoms

  • Check Engine Light illuminated
  • Hard starting or no start
  • Intermittent stalling
  • Erratic idle speed
  • Engine hesitation or misfire

Most Common Causes

Faulty crankshaft position sensor high

Sensor fails to produce expected signal waveform or frequency

Damaged wiring or sensor connector issues high

Corroded, frayed, open, or shorted wiring in CKP circuit

Damaged or misaligned reluctor ring medium

Broken or missing teeth on reluctor/tone ring cause improper signal

ECM/PCM irregularity or failure low

Control module may misinterpret valid signal or internal fault

Diagnostic Steps

  1. Connect OBD‑II scan tool and confirm P0336 and any related codes
    Expected: P0336 present and related codes (e.g., P0335, P0337) if applicable
    Interpretation: Validates DTC presence before further diagnosis
  2. Visually inspect crankshaft position sensor wiring and connector for damage or corrosion
    Expected: Wiring intact, clean, and connected securely
    Interpretation: Damaged wiring often causes signal issues leading to code
  3. Use multimeter or oscilloscope to measure CKP sensor signal and compare to manufacturer specifications
    Expected: Consistent square/AC waveform within spec
    Interpretation: Out‑of‑range signal indicates sensor or reluctor issue
  4. Inspect reluctor ring for missing teeth, debris, or misalignment
    Expected: Reluctor ring intact and properly aligned
    Interpretation: Damaged ring can distort sensor readings
  5. Replace crankshaft position sensor if wiring and reluctor are good but signal remains invalid
    Expected: Signal returns to proper range and code clears
    Interpretation: Faulty sensor likely cause

Repair Solutions

Replace crankshaft position sensor medium
Estimated Cost: $175 - $350

Typical first‑line repair if sensor fails testing

Repair or replace damaged wiring/connectors medium
Estimated Cost: $50 - $250

Includes harness repair, cleaning contacts, or replacing connector

Replace or repair damaged reluctor ring hard
Estimated Cost: $750 - $2500

May require significant disassembly depending on vehicle

ECM reprogram or replacement hard
Estimated Cost: $250 - $2500

Consider only after ruling out sensor, wiring, and reluctor issues

Common Misdiagnoses

Avoid these common diagnostic mistakes:

  • Replacing crankshaft position sensor without checking wiring or reluctor ring
  • Misidentifying a camshaft position sensor fault as P0336
  • Assuming ECM failure without verifying physical sensor circuit integrity
