What vehicles are most commonly affected by P0375?
P0375 is commonly found in 2005-2010 Ford F-150 models, but it can also affect other vehicles from manufacturers like Chevrolet and Dodge that utilize similar crankshaft position sensors.
How can I prevent P0375 from happening again?
Regular vehicle maintenance, including inspections of the crankshaft position sensor and wiring, can help prevent issues. Keeping the engine clean and ensuring proper installation during repairs also contributes to long-term reliability.
What is P0375?
The Diagnostic Trouble Code (DTC) P0375 indicates a problem with the Crankshaft Position Sensor 'A', which is crucial for monitoring the position and rotational speed of the crankshaft. This information is vital for the Engine Control Module (ECM) to manage fuel injection and ignition timing effectively. When the ECM detects that the signal from the crankshaft position sensor is out of range or performs erratically, it triggers the P0375 code. This can lead to various performance issues, including engine misfires, stalling, or rough idling. For example, in Ford F-150 models from 2005 to 2010, drivers may notice a decrease in acceleration or experience unexpected stalling. The code can also affect fuel efficiency significantly, as the engine may not run optimally without accurate crankshaft position data. Addressing this issue promptly is crucial, as ignoring it could lead to more severe engine problems over time. If you're seeing the P0375 code, it’s essential to diagnose the underlying cause correctly to avoid further complications and ensure your vehicle operates smoothly.

Symptoms
Common symptoms when P0375 is present:
- The Check Engine Light illuminates consistently, signaling a potential issue with the crankshaft position sensor.
- You may experience engine hesitations during acceleration, making it feel sluggish or unresponsive, particularly when merging onto highways.
- Fuel economy may decrease significantly, with drivers reporting a drop of 10-15%, indicating that the engine is not operating efficiently.
- Rough idling occurs, where the engine shakes or vibrates noticeably while at a stop, impacting overall driving comfort.
- Unexplained stalling may happen, especially at low speeds, which poses safety risks while driving.
Possible Causes
Most common causes of P0375 (ordered by frequency):
- The most common cause, accounting for about 60% of P0375 cases, is a faulty crankshaft position sensor that fails to send accurate signals to the ECM.
- Another possible cause is damaged wiring or connectors leading to the crankshaft position sensor, which can interfere with signal transmission.
- Improper alignment of the crankshaft sensor or the reluctor wheel can lead to misreadings, often due to wear over time; regular checks can prevent this.
- Less common but serious causes include a malfunctioning ECM that fails to interpret the sensor signals correctly, requiring specialized diagnostics.
- In rare cases, a foreign object obstructing the sensor or its wiring can lead to inaccurate readings, highlighting the importance of regular vehicle inspections.
