Your car’s check engine light can turn on for countless reasons. We recommend using an OBD-II scanner to find the potential causes of the problem. If your scanner shows a P0365 code, you’ll need to follow vehicle-specific diagnostic procedures to properly address it.
P0365 is a generic powertrain trouble code for “Camshaft Position Sensor ‘B’ Circuit Bank 1.” Many modern vehicles from BMW, Toyota, Subaru, Honda, Hyundai, Dodge, Kia, Mitsubishi, Lexus, and other automakers can have problems that trigger the P0365 code.
The camshaft position sensor monitors the rotational position of the camshaft and sends that data signal to the powertrain control module (PCM) to operate the fuel injectors and, in some cases, the ignition coils and variable valve timing system.
A P0365 code may be set if the PCM detects an irregular signal from the camshaft position sensor. You shouldn’t assume that a stored P0365 code can be fixed by replacing the camshaft position sensor itself. There might be other problems involving (but not limited to) the sensor, wiring, or the PCM.
Chevy defines the P0365 as a problem with the “Exhaust Camshaft Position Sensor Circuit.”
On engines with separate intake and exhaust camshafts also equipped with variable valve timing, these cam sensors provide the ECM/PCM feedback for VVT operation and to determine injector and ignition system synchronization.
Exhaust cam sensor information is used to determine the optimum ignition and injection points of the engine as well as keeping track of the crank/cam index relationship.
If the exhaust camshaft input doesn’t match the profile store for crank and exhaust camshaft sync, code P0365 is stored. A technician will use a scope trace taken from the vehicle and compare it to a known good scope trace for diagnosis.
Several problems may cause the PCM to store a P0365 code, so make sure to check all the parts in your circuit to ensure a proper diagnosis. Here are some of the possible causes of the P0365 code:
In the event that your OBD-II scanner reads more than one diagnostic trouble code (DTC), you might observe some symptoms not listed here. However, if your PCM only stores a P0365 code, your vehicle might exhibit one or more of the following symptoms:
The P0365 code might share similar symptoms, causes, and affected areas with other diagnostic trouble codes, which can make it difficult to diagnose. The following video can help guide you through the general diagnostic process:
There’s no magic bullet to solve a P0365 code. You must pinpoint the underlying causes of this DTC to figure out the right fix. If you don’t have much automotive repair experience, it might be best to have your vehicle serviced by a certified mechanic. They can perform the necessary repairs to get your vehicle back on the road.
Some repair procedures might not be applicable for your vehicle’s make and model. What might work to resolve a P0365 code in a BMW might not work for a Toyota. If you want to learn more about the P0365 code, there are online OBD-II resources that contain detailed information and repair instructions for your vehicle. We recommend consulting a repair manual or repair database. These manuals contain illustrations and diagrams to help you better understand the problem.
It’s not a good idea to leave DTC P0365 unaddressed. Your vehicle’s engine may become difficult to start or frequently misfire. While there is more than one possible reason for this code to be set, the most common is a malfunctioning camshaft position sensor.
If the sensor is indeed responsible, it’s time to get a replacement. Fortunately, finding a replacement camshaft position sensor is easy with the help of CarParts.com.
