P0335 Code: Dodge Durango (2021-2024) - Causes, Symptoms & Fixes

No recalls found in NHTSA database

Note on data: The provided data indicates no owner complaints and no recalls for 2021–2024 Dodge Durango with this DTC. This guide uses general automotive knowledge for diagnosis and repair, and clearly notes the data limitations where applicable.

CODE MEANING AND SEVERITY

• Code meaning: P0335 = Crankshaft Position Sensor A Circuit Malfunction. This means the Powertrain Control Module (PCM) is not receiving a valid crankshaft position signal from Sensor A, or the signal is out of expected range.
• Likely impact on the Durango: High. This fault often prevents the engine from starting or causes stalling, misfires, or poor drivability. Depending on the vehicle’s current state, you may experience long cranks, no-start conditions, or the engine running very roughly or in a "limp" mode.
• Important note: In many engines, the crankshaft position signal is used to control fuel delivery and ignition timing. A loss or corruption of this signal can cause the PCM to halt normal operation to protect the engine.

COMMON CAUSES ON DODGE DURANGO

• Faulty crankshaft position sensor (CKP) itself
• Damaged or corroded CKP sensor connector or wiring harness (loose connector, broken wire, exposed insulation, shorts to ground or power)
• Wiring routing damage due to heat, vibration, or contact with moving parts
• Sensor misalignment or improper mounting (incorrect gap/air gap, missing spacers, or incorrect torque)
• Faulty reluctor ring or damage to the crankshaft reluctor teeth (tone ring) that the CKP reads
• PCM power or ground issues or corrupted software (less common, but possible)
• Oil leaks or contamination around the sensor area (oil in sensor cavity can affect readings)
• Following engine work: improper reassembly or disturbed sensor due to timing cover work or engine service

SYMPTOMS

• Check Engine Light (MIL) on or blinking
• Engine crank/no-start condition or extended cranking
• Engine stumbles, misfires, or runs rough when it does start
• Stalling during idle or while driving
• Reduced power, sometimes entering a limp mode
• Inconsistent or intermittent no-signal behavior (appears/disappears with vibration, heat, or humidity)

DIAGNOSTIC STEPS

Note: These steps are a practical checklist. Always follow the service manual for precise specifications and procedures for your exact Durango engine (3.6L Pentastar is common, as is the 5.7L Hemi in some trims).

A. Verify the DTC and data
-Scan for P0335 with a reliable OBD-II scanner.
-Check freeze-frame data and any related faults (P0336–P0339 variants if present).
-Note engine RPM at startup and during cranking; look for missing or irregular crank signal in live data.

B. Visual inspection of the CKP circuit
-Inspect the CKP sensor and its connector for signs of corrosion, oil intrusion, or physical damage.
-Inspect the wiring harness for wear, chafing, heat damage, or loose routes that could rub on pulleys or brackets.
-Check for oil leaks around the sensor location (oil can blind or contaminate the sensor input).

C. Inspect sensor installation and mechanical condition
-If accessible, verify the sensor mounting: proper depth/air gap as specified in service information; ensure mounting fasteners are torqued to spec.
-Inspect the crankshaft reluctor ring or tone wheel for damage, missing teeth, or debris.

D. Electrical tests (use a DVOM/multi-meter and reference the service manual for exact specs)

• Power and ground to CKP sensor: verify the sensor receives proper supply voltage (per engine family, often a 5V supply from the PCM or a switched power line) and that the signal return/ground is solid.
• Resistance test (if CKP is a passive sensor or if the manual specifies a resistance check): measure the sensor’s resistance and compare to the manufacturer’s specification.
• Signal test with a scan tool: watch CKP input live data during cranking. A healthy CKP will produce a predictable waveform or digital signal; a flatline or highly erratic signal indicates sensor or wiring failure.
• If possible, probe the sensor connector pins while cranking to verify that the signal is reaching the PCM (no voltage drop or open circuit).

E. Mechanical/related checks

• If the engine recently had timing work or belt/chain work, verify timing alignment and crank/cam timing marks; incorrect timing can cause crank sensor symptoms or misdiagnosis.
• Check for oil pressure/quality issues if the vehicle has other oil-system concerns that could affect sensors.

F. Decide on replacement or further testing

• If the CKP sensor and wiring test within spec and the PCM has proper power/ground and the signal still isn’t read, consider PCM fault or firmware issue (rare; may require dealer-level testing or reprogramming).
• If the CKP sensor or wiring shows obvious defects (damaged connector, corroded pins, bare wires), replace the sensor and/or repair wiring as needed. Re-test after repair.

RELATED CODES

• P0335 is part of the CKP family. Related codes (though may vary by model/year) include variants such as P0336, P0337, P0338, and P0339, which reference different ranges, inputs, or intermittent behavior of the crankshaft position circuit.
• Some Durango engines may also show related or concurrent codes involving ignition or sensor circuits. Always check for any other codes that could point to sensor power, ground, or PCM issues (e.g., P0350–P0355 related to coil/circuit issues, though not specific to CKP).

REPAIR OPTIONS AND COSTS (2025 PRICES)

Prices vary by region, labor rate, whether OEM or aftermarket parts are used, and the engine variant. The figures below are typical ranges you might expect in 2025 for Dodge Durango models (3.6L or 5.7L engines). All costs are approximate and shown as ranges.

DIY vs PROFESSIONAL

• DIY when:
  • You have a reliable set of automotive tools, a good DVOM or multimeter, and the ability to safely work around the engine bay.
  • The CKP sensor is relatively accessible (some Durango layouts allow sensor replacement from the wheel well or under-hood access without full engine removal).
  • You can properly disconnect the battery, avoid short circuits, and follow torque specs when reinstalling.
• Professional when:
  • The CKP wiring harness is damaged in hard-to-reach areas or in a way that requires engine removal or timing cover work.
  • There is ambiguity about PCM integrity or if a software update or re-flash is needed.
  • You lack the tools for precise electrical testing or for removing components to access the sensor.
• General DIY steps (high level):
  • Disconnect the battery.
  • Locate the CKP sensor (location varies by engine; common around the crank pulley or timing cover area).
  • Inspect and, if needed, replace the sensor and any corroded wiring or connectors.
  • Reconnect, clear codes, and perform a road test to verify repair.
  • If the code returns, or if the vehicle still won’t start, seek professional diagnostic services.

PREVENTION

• Regular inspection of sensor wiring: look for cracked insulation, worn sheathing, or signs of heat damage.
• Keep the engine bay clean and dry; promptly fix oil leaks near the sensor area.
• Use OEM or high-quality sensors and connectors; avoid generic low-cost parts that can have poor tolerances.
• Ensure proper sensor installation: use correct torque on mounting fasteners and correct air-gap alignment if specified.
• If performing major engine work or timing work, ensure the CKP sensor alignment is rechecked after reassembly.
• Address drivability issues promptly: misfires, stalling, or hard starting should be diagnosed early to prevent sensor or wiring damage.
