Crankshaft Position Sensor: P0336 Crankshaft Position Sensor Location
A crankshaft position sensor is a vital component in the electronic engine management system of a vehicle. Its primary function is to monitor the crankshaft’s rotational position and speed, providing crucial information to the engine control unit (ECU) for various engine management tasks.
The crankshaft position sensor is typically located in close proximity to the crankshaft, either on the front or rear of the engine block. In inline engines, the sensor is usually mounted near the flywheel or timing belt pulley. In V-type engines, the sensor is often located on the side of the engine block, near the crankshaft pulley or camshaft.
Location and Functionality
The location of the crankshaft position sensor affects its functionality in several ways:
- Accuracy:The closer the sensor is to the crankshaft, the more accurate its readings will be. This is because the sensor can detect the crankshaft’s position and speed with greater precision when it is in close proximity.
- Durability:Sensors located away from the crankshaft may be exposed to harsh conditions, such as heat and vibration. This can affect their durability and lifespan.
- Accessibility:Sensors located in easily accessible areas are easier to inspect, maintain, and replace if necessary.
Identifying the Crankshaft Position Sensor
Locating the crankshaft position sensor in an engine bay is crucial for troubleshooting and replacement. Several methods can assist in identifying the sensor’s position.
One common approach is to refer to the vehicle’s service manual or consult online resources that provide specific information for the particular engine type. These resources often include diagrams or illustrations indicating the sensor’s location.
Visual Inspection
Visually inspecting the engine bay can also aid in locating the crankshaft position sensor. The sensor is typically a small, cylindrical device with a connector attached to one end. It is often mounted on or near the engine block, close to the crankshaft.
Diagnostic Tools
Diagnostic tools, such as an OBD-II scanner or a multimeter, can also be used to identify the crankshaft position sensor. By connecting the scanner to the vehicle’s diagnostic port, it is possible to retrieve trouble codes related to the sensor.
A multimeter can be used to test the sensor’s electrical continuity and resistance.
Common Sensor Locations
| Engine Type | Common Location |
|---|---|
| Inline Engines | At the rear of the engine block, near the flywheel |
| V-Type Engines | Between the cylinder banks, near the crankshaft |

Sensor Specifications and Compatibility
Crankshaft position sensors (CPS) have specific technical specifications that determine their functionality and compatibility with different engine models. Understanding these specifications is crucial for proper sensor selection and replacement.
The following table summarizes the key specifications of CPSs:
| Specification | Description |
|---|---|
| Voltage Range | The range of voltage that the sensor can operate within, typically between 5 and 12 volts. |
| Frequency | The number of pulses generated by the sensor per second, which corresponds to the engine speed. |
| Pulse Width | The duration of each pulse generated by the sensor, which can vary depending on the engine’s operating conditions. |
It is essential to ensure that the replacement CPS is compatible with the specific engine model. Incompatible sensors may not provide accurate signals or may even damage the engine. Factors to consider when selecting a replacement sensor include:
- Engine model and year
- Sensor type (e.g., inductive, Hall effect)
