7.3 crank position sensor symptoms
What happens when the crank position sensor goes bad?
A failing crankshaft position sensor in a 7.3 Powerstroke engine can cause several noticeable 7.3 powerstroke crank sensor symptoms:
- Rough Idle: The engine may idle roughly or shake more than usual.
- Hard Start: You might experience difficulty starting the engine, especially when it’s cold.
- Engine Stalling: The engine could stall unexpectedly, particularly at low speeds or while idling.
- Check Engine Light: The check engine light may come on, and diagnostic trouble codes related to the crankshaft position sensor could be stored in the ECM.
- Poor Acceleration: There might be hesitation or a lack of power when you try to accelerate.
- Increased Fuel Consumption: The engine might consume more fuel than usual, leading to poor fuel economy.
- Long Crank Time: The engine may take longer to start, requiring more cranking time.
What are the symptoms of a bad crank sensor on a diesel engine?
A failing crank position sensor in a diesel engine can cause several noticeable 7.3 cps sensor symptoms, including:
- Difficulty Starting: The engine may crank but struggle to start, or it might not start at all.
- Intermittent Stalling: The engine could stall unexpectedly, especially at low speeds or while idling.
- Check Engine Light: The check engine light may illuminate, indicating a problem with the sensor.
- Poor Acceleration: You might notice hesitation or a lack of power when you try to accelerate.
- Reduced Fuel Efficiency: The engine might consume more fuel than usual, leading to poor fuel economy.
- Engine Vibrations: The engine could run roughly or vibrate more than normal.
- Misfires: You might experience misfires in one or more cylinders, causing rough running.
These symptoms occur because the crankshaft position sensor provides critical information about the engine’s position and rotational speed, which is essential for proper fuel injection and ignition timing.
How to tell if a camshaft position sensor is bad on a Ford?
A bad camshaft position sensor on a Ford can exhibit several symptoms that affect the engine’s performance. ford 7.3 crank position sensor symptoms:
- Check Engine Light: The check engine light may illuminate, indicating a problem with the sensor.
- Engine Misfires: You might notice misfires in one or more cylinders, causing rough running.
- Poor Engine Performance: The engine may hesitate or lack power when you try to accelerate.
- Difficulty Starting: The engine might crank but struggle to start, or it might not start at all.
- Rough Idle: The engine may idle roughly or shake more than usual.
- Transmission Issues: You could experience shifting problems or the vehicle might go into limp mode.
- Increased Fuel Consumption: The engine might consume more fuel than usual, leading to poor fuel economy.
What is the recall on the 7.3 cam sensor?
The recall on the 7.3L Powerstroke engine, identified as Recall 07S57, involves the Camshaft Position (CMP) Sensor. The recall was issued due to potential circuit degradation in the sensor, which could cause the engine to stall unexpectedly. This stalling could lead to a loss of control and potentially result in a crash.
Details of the Recall:
- Affected Vehicles: Certain 1997-2003 Ford F-Super Duty, Excursion, and E-Series vehicles equipped with 7.3L diesel engines.
- Service Action: Dealers are required to inspect the CMP sensor and replace it with an improved version if necessary. This service is performed at no charge to the vehicle owner.
- Notification: Owners of affected vehicles were notified in phases, starting in December 2007.
