Code P1337 Description
The P1337 diagnostic trouble code indicates that the crankshaft position sensor 2 is not sending a signal to the engine control module (ECM). The crankshaft position sensor is a vital component in modern engine management systems, as it monitors the position and rotational speed of the crankshaft. This information is crucial for the ECM to accurately control fuel injection, ignition timing, and other engine functions. When the sensor fails to send a signal, it can lead to significant drivability issues and potentially cause the engine to stall or misfire.
Common Causes of P1337
- Faulty crankshaft position sensor
- Wiring or connector issues
- Sensor alignment or installation problems
- ECM software or hardware malfunctions
- Engine timing belt or chain issues
Symptoms of P1337
- Engine misfires or stalls
- Decreased fuel efficiency
- Difficulty starting the engine
- Rough idling
- Illumination of the check engine light
How to Fix P1337
- Diagnose the issue by connecting a diagnostic scanner to retrieve the specific fault code.
- Inspect the crankshaft position sensor and its wiring for any visible damage or corrosion.
- Test the sensor using a multimeter to verify if it is sending a signal.
- Replace the faulty sensor if necessary, ensuring proper alignment and connection.
- Clear the fault code from the ECM's memory and test the vehicle to confirm that the issue has been resolved.
Cost to Fix P1337
The cost of repairing a P1337 code can vary depending on the cause of the issue and the labor rates in your area. In general, replacing a crankshaft position sensor can range from $100 to $300, including parts and labor. However, additional diagnostic time may be required to pinpoint the exact cause of the problem, which can affect the overall cost. It's recommended to consult with a trusted mechanic or auto repair shop to get a more accurate estimate based on your specific vehicle and location.
