If you’re a motorcycle owner, you know that diagnosing error codes can be a frustrating experience. One of the most common error codes that you may encounter is P1335, which indicates a crankshaft position sensor ‘B’ circuit malfunction. This error code can cause your motorcycle to run poorly or even stall out completely, making it important to diagnose and repair the issue as soon as possible.
The crankshaft position sensor is a crucial component of your motorcycle’s engine management system. It detects the position and speed of the crankshaft, allowing the engine control module (ECM) to determine the correct timing for fuel injection and ignition. If the sensor malfunctions, it can cause a variety of issues, including poor performance and reduced fuel efficiency. In this article, we’ll take a closer look at P1335 and explore some of the common causes of this error code. By understanding the symptoms and causes of this issue, you’ll be better equipped to diagnose and repair the problem.
Understanding Error Code P1335
If you are experiencing issues with your motorcycle’s engine, it is essential to diagnose and fix the problem as soon as possible. One of the most common error codes you may encounter is P1335, which indicates a crankshaft position sensor ‘B’ circuit malfunction.
The crankshaft position sensor is responsible for monitoring the rotational speed of the engine’s crankshaft. It sends signals to the engine control module (ECM), which uses this information to determine the position of the crankshaft and adjust engine timing accordingly. If the sensor malfunctions, it can cause various problems, including rough idling, stalling, and reduced engine performance.
To diagnose error code P1335, you will need to use an OBD-II scanner. This tool will read the error code and provide you with a description of the problem. It is essential to note that P1335 can also be triggered by issues with the wiring or connectors associated with the crankshaft position sensor. Therefore, it is crucial to inspect these components thoroughly before replacing the sensor.
If you have determined that the crankshaft position sensor is the culprit, you will need to replace it. This process typically involves removing the sensor from its location and installing a new one. It is crucial to follow the manufacturer’s instructions carefully and ensure that the sensor is installed correctly to avoid further issues.
In summary, error code P1335 indicates a problem with the crankshaft position sensor ‘B’ circuit. To diagnose and fix the issue, you will need to use an OBD-II scanner, inspect the wiring and connectors, and replace the sensor if necessary. By taking these steps, you can ensure that your motorcycle’s engine runs smoothly and efficiently.
Symptoms of a Faulty Crankshaft Position Sensor ‘B’
If you are experiencing some issues with your motorcycle, it could be due to a faulty crankshaft position sensor ‘B’. This sensor is responsible for detecting the position of the crankshaft and sending signals to the engine control module (ECM), which then adjusts the fuel injection and ignition timing accordingly. Here are some symptoms of a faulty crankshaft position sensor ‘B’:
-
Engine misfires or stalls: If the sensor is not working properly, it can cause the engine to misfire or stall. This is because the ECM is not receiving accurate information about the position of the crankshaft, and is unable to adjust the fuel injection and ignition timing accordingly.
-
Difficulty starting the engine: A faulty sensor can also cause difficulty starting the engine. This is because the ECM is not receiving the correct signals from the sensor, which can lead to improper fuel injection and ignition timing.
-
Reduced engine performance: If the sensor is not working properly, it can also lead to reduced engine performance. This is because the ECM is not able to adjust the fuel injection and ignition timing based on the position of the crankshaft.
-
Check engine light: A faulty crankshaft position sensor ‘B’ can trigger the check engine light on your motorcycle’s dashboard. If you notice this light coming on, it’s important to have your motorcycle diagnosed as soon as possible.
If you are experiencing any of these symptoms, it’s important to have your motorcycle diagnosed by a qualified technician. They will be able to determine if the issue is due to a faulty crankshaft position sensor ‘B’, and replace it if necessary.
Can the Fix for Camshaft Position Sensor Circuit Faults in Motorcycles Also Apply to Crankshaft Position Sensor Circuit Malfunctions?
When addressing crankshaft position sensor circuit malfunctions in motorcycles, the same approach for fixing camshaft position sensor faults can often be applied. It’s important to check for loose connections, damaged wiring, or sensor damage, and then replace or repair as needed to resolve the issue.
Diagnostic Procedures for P1335
If you encounter the P1335 error code on your motorcycle, it is important to diagnose the issue correctly to ensure proper repairs. Here are some diagnostic procedures you can follow:
-
Check the wiring harness: The first step is to inspect the wiring harness for any damage or loose connections. Make sure that all connections are tight and secure. If you find any damaged wires, replace them.
-
Check the sensor: The next step is to check the crankshaft position sensor. Inspect it for any damage or wear and tear. If you find any issues, replace the sensor.
-
Check the sensor circuit: Use a multimeter to test the sensor circuit. Check for continuity between the sensor and the PCM. If there is no continuity, there may be a problem with the circuit.
-
Check the PCM: If the sensor and circuit are functioning correctly, the issue may be with the PCM. Use a scan tool to check the PCM for any error codes. If there are any error codes related to the crankshaft position sensor, replace the PCM.
By following these diagnostic procedures, you can identify the root cause of the P1335 error code and make the necessary repairs to your motorcycle.
Troubleshooting the Crankshaft Position Sensor ‘B’ Circuit
If you are experiencing error code P1335 on your motorcycle, it is likely due to a malfunction in the crankshaft position sensor ‘B’ circuit. Troubleshooting this issue can be a bit tricky, but with the right tools and knowledge, you can get your motorcycle running smoothly again.
Here are some steps you can take to troubleshoot the crankshaft position sensor ‘B’ circuit:
-
Check the wiring: The first thing you should do is check the wiring for any damage or corrosion. Make sure all connections are secure and free of debris. Look for any broken or frayed wires, and replace them if necessary.
-
Inspect the sensor: Check the sensor itself for any damage or wear. Look for any cracks or corrosion on the sensor, and make sure it is properly installed. If the sensor is damaged or worn, it will need to be replaced.
-
Test the sensor: Use a multimeter to test the sensor for proper voltage and resistance. Refer to your motorcycle’s service manual for specific instructions on how to test the sensor. If the sensor is not functioning properly, it will need to be replaced.
-
Check the reluctor ring: The reluctor ring is a toothed wheel that the sensor reads to determine the position of the crankshaft. Check the reluctor ring for any damage or missing teeth. If the reluctor ring is damaged, it will need to be replaced.
-
Test the circuit: Use a diagnostic tool to test the circuit for any faults or errors. This will help you determine if there are any issues with the circuit that need to be addressed.
