P2094: B Camshaft Position Actuator Control Circuit Low Bank 2
The P2094 code indicates that the engine control module (ECM) has detected a low voltage condition in the control circuit of the B camshaft position actuator on Bank 2. This actuator adjusts camshaft timing for optimal performance and emissions. A low circuit signal suggests a short to ground, open circuit, or faulty actuator, potentially causing poor engine performance and increased emissions.
01. Most Common Causes
- Faulty camshaft position actuator solenoid
- Open or shorted wiring in the actuator control circuit
- Poor electrical connection at the actuator or ECM
- Failed ECM (rare)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Rough idle or engine misfire
- Reduced engine power and fuel economy
- Failed emissions test
03. Step-by-Step Diagnosis
Step 1: Use a scan tool to verify the code and check for related codes.
Step 2: Visually inspect the wiring and connector for damage, corrosion, or loose pins.
Step 3: Test the actuator solenoid resistance with a multimeter (compare to specs).
Step 4: Check for voltage and ground at the actuator connector with the engine running.
Step 5: If wiring and actuator are good, test the ECM output circuit.

05. 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, reduced fuel economy, and potential damage to the catalytic converter.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for diagnosis and repair, depending on whether the issue is a simple wiring fix or requires replacing the actuator solenoid.
