All You Need to Know About P0335 Error Code

Among the many ways a vehicle communicates its health issues, error codes play a crucial role. The P0335 code, in particular, is a significant signal that can indicate serious problems within the engine. In this article, we'll explore the P0335 code in detail, from its meaning and causes to diagnosis, repair, and prevention. Whether you're a DIY - car enthusiast or someone who simply wants to be more informed about vehicle maintenance, this guide will provide you with all the knowledge you need to handle P0335 - related issues.

1. The Meaning of the P0335 Code

The P0335 code is defined as "Crankshaft Position Sensor 'A' Circuit Malfunction". The crankshaft position sensor is a vital component in a vehicle's engine management system. It monitors the position and speed of the crankshaft, which is essential for the engine control module (ECM) to accurately control ignition timing, fuel injection, and other engine functions. When the ECM detects an issue with the signal from the crankshaft position sensor 'A', such as an inconsistent or missing signal, it sets the P0335 code.

2. Possible Causes of the P0335 Code

• Faulty Sensor: The crankshaft position sensor itself may be damaged due to wear and tear over time, exposure to extreme temperatures, or manufacturing defects.A malfunctioning sensor can send incorrect or no signals to the ECM.
  
  
• Wiring and Connector Problems: Damaged, frayed, or corroded wiring can disrupt the electrical connection between the sensor and the ECM. Loose connectors can also lead to intermittent or poor signal transmission.
  
  
• Engine Mechanical Issues: Problems within the engine, such as a damaged crankshaft, flywheel, or timing belt, can cause abnormal movement of the crankshaft, which may affect the sensor's ability to accurately detect its position.
  

3. Common Causes of P0335

• Sensor Contamination: Dirt, oil, or debris can accumulate on the sensor, interfering with its ability to detect the magnetic field changes associated with the crankshaft's rotation. This is a common cause, especially in engines with oil leaks or in vehicles operating in dusty environments.
  
• Electrical Interference: Nearby electrical components or a malfunctioning alternator can create electromagnetic interference that disrupts the sensor's signal.
  

4. Which Cars Can Trigger the P0335 Code?

The P0335 code can be triggered in a wide range of vehicles equipped with an OBD - II (On - Board Diagnostics II) system. This includes most modern cars, trucks, and SUVs from various manufacturers such as Ford, Chevrolet, Toyota, Honda, Nissan, and many European brands like Volkswagen, BMW, and Mercedes - Benz. Any vehicle that uses a crankshaft position sensor in its engine management system is potentially susceptible to this code.

5. Severity of the P0335 Code

The P0335 code is of high severity. A malfunctioning crankshaft position sensor can lead to significant engine performance issues. The engine may misfire, have difficulty starting, or even stall while running. In severe cases, the engine may not start at all. Continued driving with this code can cause further damage to the engine, such as increased wear on engine components due to improper ignition and fuel injection timing.

6. Can I Still Drive with The P0335 Code?

It is not advisable to drive with the P0335 code. As mentioned, the engine may experience erratic behavior, including stalling, which can be extremely dangerous, especially when driving at high speeds or in traffic. Additionally, driving with a faulty crankshaft position sensor can cause long - term damage to the engine, resulting in more expensive repairs.

7. How to Solve the Problem of the P0335 Code Yourself?

• Visual Inspection: First, visually inspect the crankshaft position sensor and its wiring. Look for any signs of damage, such as frayed wires, loose connectors, or oil leakage around the sensor. Tighten any loose connections and clean the sensor if it appears dirty.
  
  
• Sensor Replacement: If the sensor shows signs of wear or damage, you can replace it. Make sure to use a high - quality replacement sensor that is compatible with your vehicle's make and model. Follow the vehicle's repair manual for proper removal and installation procedures.
  
  
• Wiring Repair: If the wiring is damaged, you may need to repair or replace the affected sections. Use appropriate electrical tape or wire connectors to fix frayed wires.

8. How to Diagnose the P0335 Code?

• Scan Tool: Use an OBD - II scan tool to read the P0335 code and any associated trouble codes. The scan tool can also provide live data, allowing you to monitor the sensor's signal output.
  
  
• Multimeter Testing: Use a digital multimeter to test the sensor's resistance and voltage output. Compare the readings with the specifications in the vehicle's repair manual. Abnormal readings indicate a faulty sensor.
  
  
• Mechanical Inspection: Inspect the engine's mechanical components, such as the crankshaft, flywheel, and timing belt, for any signs of damage or misalignment.

In this blog, we’ll cover the causes, symptoms, and fixes for P0335, and explain how the iCarsoft CR MAX Vehicle Diagnostic Tool from www.icarsoft-us.com can help you diagnose and resolve this issue.

9. How Much Does it Cost to Repair the P0335 Code?

The cost to repair the P0335 code depends on the cause of the problem. If it's just a faulty sensor, the cost of a replacement sensor can range from  200, plus the cost of labor, which is typically around 1 - 2 hours of work. At an average labor rate of  150 per hour, the total cost could be between  500. If the issue is due to engine mechanical problems, such as a damaged crankshaft or timing belt, the cost can be significantly higher, potentially ranging from  2000.

10. How to Clear the P0335 Code?

• Using a Scan Tool: Connect an OBD - II scan tool to the vehicle's OBD - II port, usually located under the dashboard. Use the tool to access the vehicle's computer system and select the option to clear trouble codes.
  
  
• Battery Disconnection: Disconnect the vehicle's battery for a few minutes. This will reset the vehicle's computer system and clear the stored codes. However, this method may also clear other settings in the vehicle, such as radio presets and some vehicle - specific configurations.
  

11. How to Preventing Error Code P0335?

• Regular Maintenance: Follow the vehicle manufacturer's recommended maintenance schedule. This includes regular oil changes, which can help prevent oil leakage that could contaminate the sensor.
  
• Protect Wiring: Keep the wiring harnesses away from heat sources and sharp edges. Regularly inspect the wiring for any signs of wear or damage.
  
  
• Use Quality Parts: When replacing components, use high - quality parts that meet or exceed the original equipment manufacturer's standards.
