One of the most common issues with Ford cars is the fault code P0335, which is an indicator for the crankshaft position sensor circuit malfunction. This code is triggered when the crankshaft position (CKP) sensor signal is missing for more than a certain number of camshaft revolutions. This can be caused by a wide array of issues, such as a CKP circuit open, CKP circuit short to ground, CKP circuit short to voltage, SIGRTN circuit open, or VREF circuit open. Additionally, the CKP sensor itself might be damaged. If the fault code P0335 is triggered, the vehicle may experience a loss of power and a system warning message may appear on the instrument cluster. To fix the issue, it is necessary to investigate the causes and provide the proper solutions.
Causes and Solutions for Ford Code P0335
| Cause | Solution |
|---|---|
| CKP circuit open | Check the wiring and repair any open circuits |
| CKP circuit short to ground | Use a multimeter to identify the ground issue and repair it |
| CKP circuit short to voltage | Investigate the wiring and identify the short circuit |
| SIGRTN circuit open | Locate the open circuit and repair it |
CKP Circuit Open
The CKP circuit open is one of the most common causes of Ford Code P0335. The CKP circuit is responsible for providing power to the CKP sensor, and if there is an open connection in the wiring, the sensor will not be able to provide an accurate reading. To fix this issue, it is necessary to check the wiring and look for any open circuits. Once the open circuit has been identified, it needs to be repaired to restore the sensor’s operation.
CKP Circuit Short to Ground
Another common cause of Ford Code P0335 is a CKP circuit short to ground. This occurs when the CKP sensor is connected to a ground connection instead of a power source, which can cause the sensor to malfunction. To fix this issue, it is necessary to use a multimeter to identify the ground issue and repair it.
CKP Circuit Short to Voltage
Another cause of Ford Code P0335 is a CKP circuit short to voltage. This can happen when the wiring is connected to the wrong power source, which can cause the sensor to malfunction. To fix this issue, it is necessary to investigate the wiring and identify the short circuit. Once the short circuit has been identified, it needs to be repaired to restore the sensor’s operation.
SIGRTN Circuit Open
The SIGRTN circuit open is another common cause of Ford Code P0335. The SIGRTN circuit is responsible for providing power to the CKP sensor, and if there is an open connection in the wiring, the sensor will not be able to provide an accurate reading. To fix this issue, it is necessary to locate the open circuit and repair it.
Conclusion
Ford Code P0335 is an indicator of a malfunction with the crankshaft position sensor, which can have a variety of causes. The most common causes of this code are a CKP circuit open, CKP circuit short to ground, CKP circuit short to voltage, and SIGRTN circuit open. To fix these issues, it is necessary to investigate the wiring and provide the proper solutions. The repair of the Ford Code P0335 is essential to ensure the proper operation of the vehicle and avoid any potential problems.
