The P0335 code on a 2013 Honda CR-V indicates a fault in the Crankshaft Position Sensor A Circuit. In practice, this means the engine control module (ECM) is not receiving a stable, valid signal from the crankshaft position sensor, which can prevent the engine from starting or cause it to stall or run roughly. Diagnosis focuses on the sensor, its wiring, and the related circuitry in the ECM.
What P0335 means for your CR-V
What the crankshaft position sensor does
The crankshaft position (CKP) sensor provides the ECM with timing information necessary for ignition and fuel injection. A faulty or inconsistent CKP signal disrupts engine timing, which can lead to a no-start condition, stalling, or rough running.
Common symptoms you might notice
Before addressing the possible causes, note the typical signs associated with a CKP circuit fault. These symptoms can help you decide whether to pursue a check of the sensor and its wiring.
- Engine cranks but does not start, or starts intermittently
- Engine stalls while running or runs very roughly
- Check Engine Light (CEL) is on or flashing
- Poor idle quality or misfires
- Loss of power or entering limp mode during driving
If you observe any of these symptoms, it’s a good indication to inspect the CKP sensor circuit and related wiring rather than assuming a miscellaneous issue.
Common causes
These are the typical culprits behind a P0335 diagnosis. Understanding them can guide a focused inspection or repair plan.
- Faulty crankshaft position sensor itself
- Damaged, frayed, or corroded wiring or connectors in the CKP circuit
- Loose or poor electrical connections at the sensor or ECM
- Blown fuse or a failure in the CKP circuit power/ground supply
- Oil leaks or contamination around the sensor or reluctor ring
- Timing component issues or a damaged reluctor ring affecting sensor readings
- Faulty or marginal PCM/ECU input/output (less common, but possible)
Addressing these causes often starts with a thorough wiring inspection and sensor tests before replacing components.
Diagnosis and fixes: how to approach repairing P0335
Below is a structured approach to diagnosing and resolving the P0335 code. The steps assume a methodical check of wiring, sensor integrity, and ECU signals.
- Verify the code with a scanning tool and check for any related codes that might give more context (e.g., sensor B codes, power/ground faults).
- Locate the CKP sensor and visually inspect the sensor, its connector, and the wiring harness for damage, corrosion, oil intrusion, or loose connections.
- Check power and ground to the CKP sensor circuit using a multimeter or test light to ensure the sensor is receiving proper voltage and a solid ground.
- Test the CKP sensor signal: use a scan tool with live data or an oscilloscope to review the waveform while the engine is cranking or running. A stable, consistent signal is expected; a missing or erratic signal points to the sensor or wiring.
- If the sensor and circuit test good, consider replacing the CKP sensor as a next step, and re-test to confirm the issue is resolved.
- If a new sensor does not fix the problem, inspect the reluctor ring or timing components and consider PCM-related wiring between the sensor and ECU. In rare cases, PCM replacement or reprogramming may be required.
After completing these steps, perform a road test and re-scan to confirm the code does not return and that the engine runs smoothly.
Repair costs and timelines
Typical costs vary by shop, location, and whether other issues are found during diagnosis. The following ranges give a general idea for a CKP circuit repair on a 2013 Honda CR-V.
- Crankshaft Position Sensor replacement: part$25–$120; labor$50–$150; total roughly $75–$270
- Wiring harness or connector repair: parts minimally required; labor$80–$200; total roughly $100–$300
- PCM/ECU-related diagnostics or replacement (rare): parts$300–$1,000+; labor$100–$400; total highly variable
Real-world costs depend on whether the issue is limited to a sensor and wiring or if timing components or ECU work is needed.
Safety and driving considerations
If the ECU logs P0335, avoid extended driving with symptoms like stalling or no-start. A sudden stall can be dangerous, and repeated attempts to start a vehicle with a faulty CKP circuit can cause more damage to the fuel system or catalytic converter. Seek diagnostic help promptly and arrange a tow if the vehicle cannot be driven safely.
Summary
P0335 on a 2013 Honda CR-V is a Crankshaft Position Sensor A Circuit Malfunction. It signals a problem with the crankshaft position sensor signal or its wiring, which can cause starting issues, stalling, and rough running. Diagnosis focuses on the CKP sensor, its wiring and connections, and the ECM input. Typical fixes start with inspecting and testing the sensor and wiring, followed by replacement if needed. Costs vary but are generally modest for sensor replacement, with higher expenses if wiring, timing components, or the ECU are involved. If you experience symptoms, have the vehicle inspected by a qualified technician to confirm the cause and ensure proper repair.
