How to Fix the P0335 Code in a Dodge Charger
Encountering a P0335 code in your Dodge Charger can be worrying, but with the right information and tools, you can diagnose and potentially fix the issue yourself. The P0335 code indicates a problem with the Crankshaft Position Sensor "A" Circuit Malfunction. This sensor is crucial as it monitors the position and rotational speed of the crankshaft, which is vital for engine management.
Understanding the P0335 Code
Before diving into troubleshooting, it's essential to understand what the P0335 code means and how it affects your Dodge Charger:
- Crankshaft Position Sensor: This sensor's primary function is to determine the position or rotational speed of the crankshaft. The engine control unit (ECU) uses this data to control fuel injection and ignition timing.
- Symptoms of a P0335 Code: Common signs include engine stalling, rough running, reduced fuel efficiency, and in some cases, the engine failing to start.
Step-by-Step Troubleshooting Guide
Here’s a detailed guide to help you address the P0335 code in your Dodge Charger:
Step 1: Inspect the Crankshaft Position Sensor
- Locate the Sensor: Refer to your owner’s manual to find the crankshaft position sensor’s location in your Dodge Charger.
- Visual Inspection: Check for any visible signs of damage or wear to the sensor and its wiring. Look for cracks, loose connections, or corroded terminals.
Step 2: Check the Wiring and Connectors
- Wiring Inspection: Follow the wiring from the crankshaft position sensor back to the ECU. Look for any signs of fraying, corrosion, or damage.
- Connector Check: Ensure that all connectors are tight and free from corrosion. Clean the connectors with electrical contact cleaner if necessary.
Step 3: Test the Crankshaft Position Sensor
- Multimeter Test: Set your multimeter to the ohms setting and check the resistance of the sensor. Compare your findings with the specifications in your service manual.
- Signal Test: If the resistance checks out, measure the signal output by back-probing the sensor connector with the multimeter set to the voltage setting, while cranking the engine.
Step 4: Replace the Sensor if Necessary
- Purchase the Correct Part: If the sensor is faulty, purchase a replacement specifically designed for your Dodge Charger model.
- Installation: Replace the old sensor with the new one, ensuring it is securely connected and positioned.
Step 5: Clear the Code and Test Drive
- Code Reset: Use an OBD-II scanner to clear the P0335 code from your Dodge Charger’s ECU.
- Test Drive: Take your car for a test drive to ensure that the issue is resolved and the check engine light does not reappear.
