Dodge Code P0335: Troubleshooting and Fixing Tips for a Smooth Running Engine

If your Dodge vehicle is displaying code P0335, it is important to address this issue promptly in order to maintain a smooth running engine. Code P0335 refers to a problem with the crankshaft position sensor (CKP), which plays a crucial role in the engine's performance. This article will provide you with a comprehensive guide on diagnosing and fixing Dodge code P0335, as well as preventive measures to avoid future occurrences. By following the steps outlined in this article, you can ensure that your Dodge engine stays in optimal condition.

What is Dodge Code P0335?

Dodge code P0335 signifies an issue with the crankshaft position sensor (CKP). The CKP sensor is responsible for providing the engine control module (ECM) with information about the position and speed of the crankshaft. This data is crucial for the ECM to accurately control ignition timing and fuel delivery.

There are several potential causes for code P0335, including a faulty CKP sensor, damaged wiring or connectors, or issues with the ECM. When this code is present, it can negatively affect the engine's performance, leading to issues such as misfire, rough idle, or even stalling.

Symptoms of Dodge Code P0335

Recognizing the symptoms associated with code P0335 is crucial for timely diagnosis and repair. Some common symptoms of this code include:

• Misfire or hesitation during acceleration
• Rough idle
• Engine stalling
• Difficulty starting the engine
• Reduced fuel economy

If you experience any of these symptoms, it is important to address the issue promptly to prevent further damage to your engine.

Diagnostic Process for Dodge Code P0335

Diagnosing code P0335 requires a systematic approach. In this section, we will provide you with a step-by-step guide on how to diagnose this code and determine the underlying cause. Before starting the diagnostic process, ensure that you have the necessary tools and equipment, including a scanner, multimeter, and basic mechanic's tools.

Step 1: Inspecting the Crankshaft Position Sensor (CKP)

The CKP sensor is a key component in the diagnosis of code P0335. Start by inspecting the CKP sensor for any visible damage or signs of wear. It is crucial that the sensor is securely fastened and properly aligned. If any issues are found during the inspection, consider replacing the CKP sensor with a high-quality replacement.

Step 2: Testing the CKP Sensor Output

Testing the CKP sensor output can help determine if it is functioning properly. To perform this test, you will need a multimeter. Connect the multimeter to the CKP sensor terminals and measure the voltage or resistance. Compare the readings to the manufacturer's specifications and interpret the results accordingly. If the readings are outside of the specified range, it may indicate a faulty CKP sensor.

Step 3: Inspecting the Wiring Harness and Connectors

Check the wiring harness and connectors related to the CKP sensor for any loose connections or damaged wires. Even a minor issue can cause code P0335. Repair or replace any damaged components as necessary. Ensure that all connections are secure and properly insulated.

Step 4: Verifying the CKP Sensor Signal

Verifying the CKP sensor signal can provide further insight into the issue. Use a scanner or oscilloscope to analyze the sensor signal. Compare the signal patterns to the manufacturer's specifications and troubleshoot accordingly. If the signal patterns deviate from the expected values, it may indicate a CKP sensor or ECM issue.

Step 5: Checking the PCM

While less common, code P0335 can also be caused by issues with the Powertrain Control Module (PCM). Check the PCM for any signs of damage or malfunction. Inspect the connectors and wiring related to the PCM. If any issues are detected, consider seeking professional help to repair or replace the PCM.

How to Fix Dodge Code P0335

Based on the diagnostic results, there are several potential fixes for code P0335. The appropriate solution will depend on the underlying cause of the issue. Follow the instructions below to address the problem and ensure a smoothly running engine.

Fix 1: Replacing the Crankshaft Position Sensor

If the CKP sensor is found to be faulty during the diagnostic process, it is recommended to replace it with a high-quality replacement sensor. Follow these steps for a successful sensor replacement:

1. Disconnect the battery to prevent any electrical surges.
2. Locate the CKP sensor, typically positioned near the crankshaft.
3. Disconnect the sensor wiring harness.
4. Remove any mounting bolts or fasteners securing the sensor.
5. Install the new CKP sensor and secure it in place.
6. Reconnect the sensor wiring harness.
7. Reconnect the battery.

Ensure that the sensor is properly aligned and securely fastened to avoid future issues.

Fix 2: Repairing or Replacing the Wiring Harness

If the issue lies with the wiring harness or connectors, it is crucial to address them promptly. Minor wiring issues can sometimes be repaired by soldering or replacing damaged wires. However, if the damage is extensive, consider replacing the entire wiring harness. Follow these steps to repair minor wiring issues:

1. Disconnect the battery to prevent any electrical surges.
2. Inspect the wiring harness and connectors for any loose connections or damaged wires.
3. If loose connections are found, secure them properly.
4. If damaged wires are found, strip the damaged section and solder or replace with new wires.
5. Reconnect the battery.

If extensive wiring damage is detected, it is recommended to replace the entire wiring harness to ensure a reliable repair.

Fix 3: Addressing PCM Issues

In rare cases, code P0335 may be caused by issues with the PCM. If the previous steps do not resolve the issue, it is advisable to consult a professional technician or seek assistance from a Dodge dealership. PCM reprogramming or replacement may be necessary to fix the problem.

It is important to note that PCM repairs can be complex and require specialized knowledge and equipment. Attempting advanced PCM repairs without proper experience can lead to further issues or damage.

Preventive Measures for Dodge Code P0335

To avoid future occurrences of code P0335, it is important to take preventive measures and regularly maintain your Dodge vehicle. Follow these recommendations to keep your engine in optimal condition:

• Perform regular inspections of the CKP sensor and wiring harness
• Clean the CKP sensor as part of routine maintenance
• Ensure all connections related to the CKP sensor are securely fastened and properly insulated
• Follow the manufacturer's recommended maintenance schedule
• Address any minor issues or symptoms promptly to prevent further damage

By taking these preventive measures, you can minimize the chances of encountering code P0335 and ensure a smoothly running engine.
In conclusion, code P0335 in a Dodge vehicle indicates a problem with the crankshaft position sensor (CKP) and can negatively impact the engine's performance. It is important to promptly address this issue by following the diagnostic process outlined in this article. By inspecting the CKP sensor, testing its output, checking the wiring harness and connectors, verifying the CKP sensor signal, and addressing any PCM issues, you can successfully troubleshoot and fix code P0335.

Remember to choose the appropriate fix based on your diagnostic results and consult a professional technician if needed. Additionally, implementing preventive measures can help prevent future occurrences of code P0335 and ensure a smoothly running engine. Take action and prioritize the health of your Dodge engine for optimal performance and longevity.
