P2095 — B Camshaft Position Actuator Control Circuit High Bank 2

Manufacturer-specificPowertrain (engine & transmission)

Code P2095 indicates that the powertrain control module (PCM) has detected a high voltage condition in the control circuit for the 'B' camshaft position actuator on engine bank 2. This actuator is typically an oil control solenoid that adjusts camshaft timing, and a high circuit reading often points to an open circuit, short to voltage, or a failed solenoid.

Symptoms

What causes it — most likely first

1. Faulty 'B' camshaft position actuator solenoid (bank 2)

The solenoid itself may have an internal open circuit or high resistance, preventing proper operation and triggering the high circuit code.

2. Wiring or connector issues in the actuator control circuit

Damaged, corroded, or shorted wiring between the PCM and the actuator can cause a high voltage reading. This includes a short to voltage or an open circuit.

3. Poor electrical connection at the actuator solenoid

Loose, corroded, or pushed-out terminals at the solenoid connector can create high resistance or an open circuit, mimicking a high voltage condition.

4. Low or dirty engine oil

Insufficient oil level or degraded oil can affect the operation of the camshaft actuator, potentially causing the PCM to detect an abnormal circuit condition.

5. Faulty powertrain control module (PCM)

Rarely, an internal PCM failure can cause a false high circuit reading. This should only be considered after all other causes are thoroughly ruled out.

How it's diagnosed

  1. Check the engine oil level and condition. Low or dirty oil can cause actuator issues; top off or change oil if necessary.
  2. Visually inspect the 'B' camshaft actuator solenoid, connector, and wiring on bank 2 for obvious damage, corrosion, or loose connections.
  3. Disconnect the solenoid and measure its resistance with a multimeter. Compare to manufacturer specifications; an open circuit or out-of-range reading indicates a faulty solenoid.
  4. With the key on and engine off, check for voltage at the solenoid connector's power supply pin. Then, check the control circuit for shorts to voltage, ground, or open circuits using a wiring diagram.
  5. If all wiring and the solenoid test good, use a scan tool to command the actuator on and off while monitoring the control circuit voltage. A lack of change may indicate a PCM driver fault, but this is rare.

Frequently asked

What does 'B' camshaft position actuator refer to?

On engines with variable valve timing, 'B' typically designates the exhaust camshaft actuator solenoid. Bank 2 is the side of the engine opposite cylinder number one.

Can low oil cause a P2095 code?

Yes, low oil level or dirty oil can affect the hydraulic operation of the camshaft actuator, potentially leading to circuit-related codes. Always check oil condition first.

Is it safe to drive with a P2095 code?

While the vehicle may be drivable, it is not recommended to drive for extended periods. The code indicates a problem with camshaft timing control, which can lead to reduced performance, increased emissions, and possible engine damage.

Do I need to replace the PCM for a P2095 code?

Almost never. The PCM is very rarely the cause of this code. Replacing it without thorough diagnosis of the actuator, wiring, and oil condition is a common misdiagnosis and a waste of money.
