P2095: B Camshaft Position Actuator Control Circuit High Bank 2
The P2095 code indicates that the powertrain control module (PCM) has detected a high voltage condition in the control circuit of the camshaft position actuator for the 'B' camshaft (typically the exhaust camshaft) on engine bank 2. This actuator uses oil pressure to adjust cam timing for optimal performance and emissions. A high voltage signal suggests a short to power, faulty actuator solenoid, or wiring issues, which can prevent proper camshaft timing adjustment.
1. Most Common Causes
- Faulty VVT solenoid on bank B with altered internal resistance
- Short to battery positive (B+) in the solenoid control circuit wiring
- Loose connection or corrosion at the VVT solenoid connector
- Excessive resistance in the VVT solenoid winding
- Internal failure of the engine control module (ECM/PCM)
- Poor ground reference in the solenoid circuit
2. Symptoms You Will Notice
- Check Engine Light illuminated
- Rough idle or engine misfire
- Decreased fuel economy
- Poor acceleration or hesitation
- Failed emissions test
3. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect the actuator wiring and connector for damage, corrosion, or loose pins.
Step 3: Use a multimeter to check for voltage at the actuator connector with key on; should be battery voltage on the power wire.
Step 4: Test the actuator solenoid resistance; compare to manufacturer specs (typically 6-12 ohms).
Step 5: If wiring and solenoid are good, check for a short to power in the control circuit from PCM to actuator.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as it can cause poor engine performance, increased emissions, and potential damage to the camshaft timing components.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for parts (actuator solenoid) and labor, depending on vehicle make and shop rates.
