What is the code for the crank sensor on a Dodge?
As a seasoned auto service provider, I often encounter questions about various components of vehicles, particularly when it comes to diagnostics and repairs. One common inquiry is about the crank sensor code for Dodge vehicles. This article will delve into what the crank sensor is, its importance, and how to interpret the codes associated with it.
What is a Crank Sensor?
The crankshaft position sensor (often referred to as the crank sensor) is a critical component in modern vehicles, including Dodge models. It monitors the position and rotational speed of the crankshaft, providing essential data to the engine control unit (ECU) for optimal engine performance.
Importance of the Crank Sensor
The crank sensor plays a vital role in engine management. Here are a few reasons why it is important:
- Engine Timing: It helps in determining the precise timing for fuel injection and ignition.
- Performance: A malfunctioning crank sensor can lead to poor engine performance, stalling, or failure to start.
- Diagnostics: It provides diagnostic trouble codes (DTCs) that can help identify issues within the engine.
Common Crank Sensor Codes for Dodge Vehicles
- P0335: Crankshaft Position Sensor A Circuit Malfunction
- P0336: Crankshaft Position Sensor A Circuit Range/Performance Problem
- P0337: Crankshaft Position Sensor A Circuit Low Input
- P0338: Crankshaft Position Sensor A Circuit High Input
How to Address Crank Sensor Codes
If you encounter any of these codes, here are steps you can take:
- Check Connections: Inspect the wiring and connectors for any signs of damage or corrosion.
- Test the Sensor: Use a multimeter to test the sensor's resistance and output voltage.
- Replace if Necessary: If the sensor is faulty, replacing it is often the best solution.
- Clear Codes: After repairs, clear the codes using an OBD-II scanner and test drive the vehicle to ensure the issue is resolved.
Conclusion
Understanding the crank sensor and its associated codes is crucial for maintaining the performance of your Dodge vehicle. Regular diagnostics and timely repairs can prevent more significant issues down the line. If you're experiencing problems or have questions about your vehicle's crank sensor, don't hesitate to reach out for professional assistance.

What is the code P0344 on a Dodge Ram?
What Does the P0344 Code Mean? Diagnostic trouble code (DTC) P0344 stands for “Camshaft Position Sensor “A” Circuit Intermittent (Bank 1 or Single Sensor).” It triggers when the PCM detects a loss of signal from the Bank 1 camshaft position sensor. Bank 1 refers to the bank of the engine that contains cylinder #1.
How do I reset a crank sensor?
Shift your car to part throttle and accelerate to 55mph. Drive around and maintain a speed of 55mph for 10 minutes to let your engine reach its operating temperature. Drive around at 55mph for 5 more minutes. Decelerate and drive at a speed of 45mph for 25 seconds but do not use the brakes.
What is the code for the crank sensor circuit?
What Does the Code P0335 Mean? This is a fairly common question among vehicle owners who own a car with an OBD-II equipped vehicle. Essentially, this code refers to an issue in the crankshaft location or its relays.
What are the symptoms of a failing crank sensor?
And wanting to turn off in the stop. Position when the crankshaft. Position sensor fails the engine control module will command the fuel. And Spark at the incorrect. Time resulting in misfires.
What is the code P1DD2 on a Dodge Ram 1500?
DTC P1DD2 - Torque Request Signal From TCM Denied will be present, set by the TCM and the vehicle will be in limp home mode (Sales Codes DF5 and DF7 - Automatic Transmission Vehicles Only).
What code will a bad crankshaft sensor throw?
What Does the P0335 Code Mean? The OBD-II code P0335 is a generic diagnostic trouble code that stands for “Crankshaft Position “A” Circuit Malfunction.” The code is set when your car's primary computer—also known as the powertrain control module (PCM)—is unable to detect a signal from the crankshaft position sensor.
How to fix fault code P0335?
Check and repair timing components: Worn or loose timing belts or chains may need to be adjusted or replaced to ensure proper crankshaft positioning. Clear the code: After repairs, the error code should be cleared with an OBD-II scanner, and a test drive should be conducted to confirm the fix.
