As you’re driving down the highway, do you ever feel like your vehicle is just not performing the way it should?
Perhaps it’s sluggish, or maybe it’s stalling out frequently. If so, you could be dealing with a problem related to your crankshaft position sensor. In this article, we’re going to discuss everything you need to know about the P0337 code, which refers to the crankshaft position sensor A circuit range/performance issue.
What is the P0337 Code?
The P0337 code is a diagnostic trouble code (DTC) that is generated when the vehicle’s powertrain control module (PCM) detects a problem with the circuit that connects to the crankshaft position sensor. The sensor itself is a small electronic device that is installed near the vehicle’s crankshaft and is responsible for monitoring the rotation speed and position of the crankshaft.
When the PCM receives a signal from the crankshaft position sensor that is outside of the expected range, it will trigger the P0337 code. This can be caused by a number of issues, including a faulty sensor, damaged wiring, or a malfunctioning PCM.
Symptoms of the P0337 Code
If your vehicle has a problem with the crankshaft position sensor A circuit, you may experience a number of symptoms. These can include:
- The engine may run rough or stall out frequently
- The vehicle may be difficult to start
- The acceleration may feel sluggish or jerky
- The check engine light may be illuminated on the dashboard
If you are experiencing any of these symptoms, it’s important to have your vehicle inspected by a qualified mechanic as soon as possible.
Diagnosing the P0337 Code
Because the P0337 code can be caused by a number of different issues, diagnosing the problem can be a complicated process. A qualified mechanic will typically begin by using a diagnostic scanner to retrieve any stored DTCs from the vehicle’s PCM.
From there, the mechanic will perform a visual inspection of the crankshaft position sensor and its wiring. They may also use a multimeter to test the resistance of the sensor and the continuity of the wiring. If a problem is identified, the mechanic will be able to replace any damaged parts or repair any broken wiring.
In some cases, the P0337 code may be caused by a malfunctioning PCM. If this is the case, the PCM will need to be replaced or reprogrammed by a qualified mechanic.
Preventing the P0337 Code
One of the best ways to prevent the P0337 code from occurring is to keep your vehicle well-maintained. This includes regular oil changes, tune-ups, and inspections of the crankshaft position sensor and its wiring.
If you do experience the P0337 code, it’s important to have the problem addressed as soon as possible. Ignoring the issue can lead to further damage to your vehicle’s engine and other components.
Conclusion
The P0337 code is a serious issue that can cause a number of problems for your vehicle. If you are experiencing any of the symptoms of this issue, it’s important to have your vehicle inspected by a qualified mechanic as soon as possible. With proper maintenance and timely repairs, you can help prevent the P0337 code and keep your vehicle running smoothly for years to come.
FAQs
- Is it safe to drive with the P0337 code?
While it is technically possible to drive with the P0337 code, it is not recommended. The code can cause a number of serious problems for your vehicle and can lead to damage to your engine and other components.
- How much does it cost to repair the P0337 code?
The cost of repairing the P0337 code can vary widely depending on the specific issue that is causing the problem. In general, you can expect to pay anywhere from $100 to $500 for repairs.
- Can I fix the P0337 code myself?
While some DIY mechanics may be able to fix the P0337 code themselves, it is generally not recommended. This issue can be caused by a number of different issues, and diagnosing and repairing the problem requires specialized equipment and expertise.
- What other issues can cause the P0337 code?
In addition to issues with the crankshaft position sensor A circuit, the P0337 code can also be caused by problems with the crankshaft position sensor B circuit and the camshaft position sensor.
- How do I clear the P0337 code?
To clear the P0337 code, you will need to use a diagnostic scanner to reset the vehicle’s PCM. However, it’s important to note that simply clearing the code will not fix the underlying issue that caused it to occur in the first place.
