Diagnosing issues in your vehicle can be difficult because problems in different systems can cause similar symptoms. One way to help determine the part that’s causing problems is to use a scan tool to retrieve the logged on-board diagnostic (OBD) code. The P0366 code is one of the trouble codes that the OBD system can log.

What Does the P0366 Code Mean?

Diagnostic trouble code (DTC) P0366 stands for “Camshaft Position Sensor B Circuit Range/Performance Bank 1.”

The camshaft position sensor monitors the rotational position of the camshaft. It sends a data signal to the powertrain control module (PCM), which controls outputs, such as the fuel injectors, ignition coils, and variable valve timing system.

The P0366 code is logged once the PCM detects an issue in the signal from the sensor. The OBD system can also log this code if it doesn’t receive any signal from the camshaft position sensor.

Note: The definition of code P0366 might be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.

How to Diagnose the P0366 Code

Although the code P0366 is a generic powertrain code and may indicate similar triggers and symptoms, the steps for its diagnosis might vary from one vehicle to another.

If you’re not familiar with the process of diagnosing trouble codes on your own, it’s best to leave the job to a certified mechanic. But if you think you have the right tools and know-how to do it, then you can diagnose the issue on your own.
