P0335 Code: Dodge Charger (2021-2023) - Causes, Symptoms & Fixes

No recalls found in NHTSA database

From the data provided: No NHTSA complaints found for this make/model/year/issue combination.

Note: This guide uses general OBD-II knowledge and common Dodge Charger-specific considerations. The absence of NHTSA complaints or recalls in the supplied data does not guarantee the condition cannot occur in the real world; it simply means there were no records in the provided dataset. Costs and availability reflect typical market values as of 2025 and may vary by region, engine variant, and shop.

CODE MEANING AND SEVERITY

• Code: P0335 Crankshaft Position Sensor "A" Circuit Malfunction
• What it means: The Powertrain Control Module (PCM) did not receive a valid signal from the crankshaft position sensor (CKP) for the engine’s crankshaft reference. The “A” circuit typically refers to the primary CKP sensor circuit used by the PCM to track engine position and RPM.
• Severity: Moderate to high. The vehicle may not start, can stall, or run with poor timing and misfires. In many cases, the engine may crank without starting. Because the CKP data is used to control fuel injection timing and ignition timing, a faulty signal can lead to misfires, reduced power, and potential damage if the vehicle is driven in a symptomatic state.
• Important context for Chargers: On modern Dodge Chargers (2021–2023), multiple engine configurations exist (various Hemi and Pentastar variants). The CKP sensor is critical for proper engine timing management across all variants. If P0335 is stored, expect potential signs of intermittent starting issues, stalling, or poor idle quality, especially during cold starts or under load.

COMMON CAUSES ON DODGE CHARGER

• Faulty crankshaft position sensor (CKP) itself
• Damaged, pinched, corroded, or contaminated wiring harness or connector between the CKP sensor and the PCM
• Loose, damaged, or corroded CKP sensor connector or ground/5V reference pins
• Oil leaks or excessive engine oil contamination around the sensor area
• Damaged reluctor ring or crankshaft timing components (e.g., misalignment, wear, or debris affecting the signal)
• PCM/ECU fault or corrupted software (less common, but possible)
• Electrical system issues: weak battery, alternator problems, or high resistance/voltage drop affecting sensor signal
• Misinstallation after timing belt/chain service or engine work

SYMPTOMS

• Engine cranks but won’t start, or starts intermittently
• Stalling or hesitation while driving
• Rough idle or misfires; rough running
• Check Engine light (CEL) or MIL illuminated
• Reduced power or limp-home mode in some vehicles
• Tachometer behavior may be erratic or wrong when the CKP signal is lost
• In some cases, related cylinder misfire codes (P0300-P0308 family) may accompany P0335

DIAGNOSTIC STEPS

Note: Always start with basic checks and move to targeted CKP testing. Use OEM service information when available for exact pinout and tests.

A. Prepare and verify

• Use a quality OBD-II scanner to confirm P0335 and check for related codes (P0336–P0339, P030x, P0620, etc.).
• Review freeze frame data: RPM reading, engine load, ignition timing values, and any voltage anomalies at the time of the fault.

B. Inspect basic power and grounding

• Check battery voltage (should be ~12.6V at rest; higher during cranking). A weak battery or charging issue can cause false CKP readings.
• Inspect main engine grounds and PCM ground connections. Clean and retorque as needed.
• Inspect the CKP sensor power supply (5V reference) and signal return line for corrosion, loose connections, or damaged insulation.

C. Visual and connector inspection

• Locate CKP sensor(s) on the engine. For Dodge Chargers, this is typically mounted near the crankshaft pulley or at the front of the engine, depending on engine variant.
• Inspect the sensor and wiring harness for oil leaks, heat damage, abrasion, or tight routing near moving or hot surfaces.
• Disconnect and inspect the CKP sensor connector; ensure the pins are clean, properly seated, and not bent or corroded. Use electrical contact cleaner and dielectric grease upon reassembly if appropriate.
• Check for oil or solvent contamination on the sensor face or reluctor area.

D. Electrical tests (requires appropriate tools)

• Continuity and resistance test: With the harness disconnected, measure the resistance of the CKP sensor circuit (per factory spec). The exact resistance can vary by sensor type (some are passive/reluctance sensors with no simple resistance spec; others are Hall-effect with a 5V supply and a ground). If the resistance is outside spec or the circuit shows a short to ground or to power, replace the sensor and/or repair wiring.
• Voltage reference test: With the ignition ON (engine off), check for 5V reference at the sensor’s reference pin and confirm there is a solid ground at the ground pin. Any voltage drop or intermittent connection can indicate wiring problems.
• Signal test with engine running (scope or qualified scanner): Use an oscilloscope or a capable scan tool to observe the CKP signal waveform. A healthy CKP signal shows a clean, periodic waveform corresponding to crankshaft rotation. A missing, intermittent, or highly noisy signal suggests sensor or wiring fault.
• Check for a proper wheel/reluctor signal: If your engine has a reluctor-ring-based CKP, inspect the reluctor ring for cracks, missing teeth, or debris that could compromise the signal.

E. Mechanical and related checks

• If timing components were recently replaced or serviced, confirm correct installation and timing alignment. A misaligned timing system can cause CKP signaling issues and mis-timing that tricks the PCM into diagnosing P0335.
• Inspect for timing chain/belt wear or a jumped timing event, though this is a less frequent cause for P0335 alone and more often causes broader timing-related codes.

F. PCM/software considerations

• Check for any available software updates or reprogramming advisories from the OEM. If a known software/immobilizer interaction exists, a service bulletin or update may address CKP signal handling.
• After replacing CKP sensor or repairing wiring, some vehicles require a crankshaft position learn or relearn procedure. Follow OEM guidance if applicable.

G. Confirm the fix

• Clear codes and perform a road test or simulated drive (with a diagnostic scan tool able to log CKP data in real time) to verify that P0335 does not return and that related symptoms are resolved.

Notes:

• If the CKP problem is intermittent, cost can be higher due to multiple diagnostic sessions.
• Some shops may quote higher for late-model Dodge vehicles due to required tooling or ECM programming.
• Always confirm whether the cost includes diagnostic time, parts, and any required ECM programming.

DIY VS PROFESSIONAL

DIY-friendly tasks (if you have mechanical skills and tools):

• Visual inspection of CKP sensor, connector, and wiring harness
• Cleaning and reseating the CKP sensor connector; applying dielectric grease if appropriate
• Checking battery voltage and charging system
• Inspecting for oil leaks and cleaning the sensor area
• Basic data logging with a compatible scanner to observe CKP signal trends (requires some knowledge)

Tasks better left to a professional:

• Replacing the CKP sensor in tight engine bays or when sensor location is difficult to access
• Inspecting or repairing wiring harnesses that run through hot or complex areas
• Wiring diagnosis (continuity, resistance tests) and pin-by-pin checks with the PCM harness
• Verifying CKP signal with an oscilloscope (advanced diagnostic technique)
• PCM replacement or reprogramming or crank relearn procedure (if required)

Safety considerations:

• Disconnect battery before performing electrical tests on the CKP circuit
• Exercise caution with airbag system and fuel system when disconnecting components
• Use proper personal protective equipment and follow shop manual procedures

PREVENTION

• Regular electrical system health: keep battery and alternator in good condition; ensure clean, tight grounds
• Protect wiring: route CKP harness away from hot surfaces and moving parts; use loom and grommets as designed
• Address oil leaks promptly to prevent CKP exposure to oil contamination, which can affect signal integrity
• Use OEM or high-quality replacement sensors and connectors to ensure proper fit and signal integrity
• If performing engine work (timing belt/chain, front cover service, etc.), follow torque specs and alignment procedures precisely; improper timing can affect CKP readings
• Schedule periodic diagnostics if the engine exhibits stalling, misfires, or starting issues, and address any electrical or sensor-related concerns early
• Keep software/ECU up to date per dealer advisories where applicable
