P0335 DTC Code: Explained in Detail


In the world of automobiles, diagnostic trouble codes (DTCs) play a vital role in identifying and troubleshooting various issues. One such code is P0335, which we will discuss in this article. So, if you’ve come across this code and want to learn more about it, you’ve landed in the right place!

Understanding P0335 DTC Code

What is a DTC Code?

Before delving into P0335 specifically, let’s quickly understand what a DTC code is. DTC stands for “Diagnostic Trouble Code.” These codes are generated by a vehicle’s onboard diagnostic system to indicate specific issues or malfunctions within the vehicle’s components or systems. These codes are standardized across different vehicle manufacturers, making it easier for mechanics and technicians to accurately diagnose and fix problems.

P0335 DTC Code Definition

The P0335 DTC code refers to a specific issue related to the vehicle’s crankshaft position sensor (CKP). This code is OBD-II (On-Board Diagnostics, Second Generation) specific, meaning it is applicable to vehicles manufactured after 1996. The CKP sensor is responsible for providing the Engine Control Module (ECM) with information about the crankshaft position and rotational speed. When the ECM detects a malfunction with this sensor, it triggers the P0335 code.

Symptoms of P0335 DTC Code

Identifying the symptoms associated with the P0335 DTC code is crucial to detect the issue and initiate timely repairs. Here are a few common symptoms that may indicate the presence of this code:

  1. Engine Misfires: A malfunctioning CKP sensor can lead to engine misfires, causing a noticeable decrease in engine performance and rough idling.

  2. Stalling or No-Start Condition: The P0335 code can sometimes result in the engine stalling or not starting at all. This can be highly inconvenient and frustrating for the driver.

  3. Illuminated Check Engine Light: When the ECM detects a problem with the CKP sensor, it triggers the check engine light on the instrument cluster. This serves as an early warning sign to get your vehicle inspected.

Causes of P0335 DTC Code

Now that you are aware of the symptoms, let’s dive into the potential causes of the P0335 DTC code. It’s important to note that these causes may vary depending on the vehicle make, model, and year. However, some common culprits include:

  • A Faulty Crankshaft Position Sensor: A defective or damaged CKP sensor can trigger the P0335 code. This can happen due to wear and tear or electrical issues.

  • Wiring or Connector Problems: Damaged wiring harnesses, loose connections, or corroded connectors can disrupt the communication between the CKP sensor and the ECM, leading to the code.

  • Sensor Alignment Issues: If the CKP sensor is not positioned correctly or is misaligned with the crankshaft, it can affect its functionality and trigger the P0335 code.

Diagnosing and Resolving P0335 DTC Code

Diagnosing the exact cause of the P0335 code is essential for effective repairs. Here are the steps a mechanic or technician may follow to address this issue:

  1. Visual Inspection: The first step involves a thorough visual inspection of the wiring, connectors, and sensor itself. Any signs of damage, fraying, or corrosion should be noted.

  2. Using Scan Tools: Diagnostic scan tools are employed to retrieve the specific code and gather additional information from the ECM. Live data and freeze frame data can help pinpoint the issue.

  3. Testing the CKP Sensor: Specialized tools are used to test the CKP sensor’s resistance, voltage, and waveform. If the sensor fails the tests, it will need to be replaced.

  4. Inspecting and Repairing Wiring: Technicians will check the wiring harness, connectors, and terminals associated with the CKP sensor. Repairing or replacing damaged components may be necessary.

  5. Clearing the Code: Once the repairs are done, the mechanic will clear the DTC code using their scan tool. This ensures the ECM is aware of the resolved issue.

Frequently Asked Questions (FAQs)

Here are some frequently asked questions about the P0335 DTC code, along with their answers:

Q1: Can I drive my vehicle with the P0335 DTC code?

A: It is generally not recommended to drive your vehicle with the P0335 code present. Continuing to operate the vehicle may cause severe engine performance issues and potential damage.

Q2: How much does it cost to fix the P0335 DTC code?

A: The cost of addressing the P0335 code can vary depending on factors like the vehicle’s make, model, and location of repair. Additionally, the specific cause of the code and the necessary repairs will also impact the overall cost.

Q3: Can I fix the P0335 DTC code on my own?

A: While some basic troubleshooting steps like inspecting for loose connections or damaged wiring can be done by vehicle owners, diagnosing and repairing the root cause of the P0335 code often requires professional expertise and specialized tools.


In conclusion, the P0335 DTC code relates to issues with the vehicle’s crankshaft position sensor (CKP). Recognizing the symptoms and understanding the potential causes can help you take the necessary steps to have your vehicle diagnosed and repaired promptly. Remember to consult an experienced mechanic or technician to ensure an accurate diagnosis and resolution of the P0335 code. Safeguard your vehicle’s performance by addressing such issues promptly!
