P2095 B Camshaft Position Actuator Control Circuit High Bank 2
OBD-II Trouble Code Technical Description
B Camshaft Position Actuator Control Circuit High Bank 2
What does that mean?
This is a generic powertrain diagnostic trouble code (DTC) and applies to many OBD-II vehicles (1996-newer). That may include but is not limited to vehicles from Subaru, Cadillac, Dodge, Mazda, Audi, Mercedes, etc. Although generic, the exact repair steps may vary depending on year, make, model and powertrain configuration.
OBD-II diagnostic code P2095 is associated with the B camshaft position actuator control circuit on bank 2. When the Engine Control Unit (ECU) detects improper signals within the B camshaft position actuator control circuit code, P2095 will be set and the check engine light will be illuminated. Some vehicles may require multiple failure cycles before the check engine light is illuminated.
The purpose of the camshaft position actuator control circuit is to monitor variations of between the camshaft/s and the crankshaft and send a corresponding signal to the ECU. This process is accomplished with camshaft and crankshaft position sensors which convert varying degrees between the camshaft/s and the crankshaft into a voltage signal that is used by the ECU to adjust the timing and optimize the performance of the engine.
This code is defined as B Camshaft Position Actuator Control Circuit High Bank 2 and indicates a detected too high of electrical condition within the B camshaft position actuator control circuit on bank 2 as mentioned earlier.
Note: The "A" camshaft is either the intake, left, or front camshaft. Conversely, the "B" camshaft is either the exhaust, right, or rear camshaft. Left/Right and Front/Rear are determined as though you are sitting in the driver's seat. Bank 1 is the side of the engine that contains the #1 cylinder, whereas bank 2 is the opposite bank. If the engine is an inline or straight design, there is only one bank.
A typical camshaft position sensor:
What is the severity of this DTC?
The severity of this code can vary tremendously from just an illuminated check engine light on a vehicle that starts and runs to an automobile that will idle rough or not start at all. The code can be serious depending on what symptoms are present. If the code is caused by a failed timing chain or belt the result can be internal engine damage.
What are some of the symptoms of the code?
Symptoms of a P2095 trouble code may include:
Rough engine idle Decreased oil pressure Engine may misfire Poor engine performance Increased fuel consumption Change oil or service soon light is illuminated Check engine light illuminatedWhat are some of the common causes of the code?
Causes for this P2095 code may include:
Worn timing belt or chain Defective camshaft variable timing solenoid Defective variable valve timing actuator Engine oil level is too low Blown fuse or fuse-able link (if applicable) Misalignment of timing components Corroded or damaged connector Faulty or damaged wiring Faulty ECUWhat are some P2095 troubleshooting steps?
The first step in the troubleshooting process for any malfunction is to research the Technical Service Bulletins (TSB's) for the specific vehicle by year, model and engine combination. In some circumstances this can save a lot of time in the long run by pointing you in the right direction.
The second step is to check the oil level and the condition of the oil. The proper oil pressure plays a key role in the function of this circuit. Then locate all of the components within this circuit and perform a thorough visual inspection to check the associated wiring for obvious defects such as scraping, rubbing, bare wires, or burn spots. Next is to check the connectors for security, corrosion and damaged pins. This process must inc
