What Does P2094 Mean?
The ECM has detected a lower than expected voltage or resistance in the exhaust camshaft position actuator control circuit for Bank 2. This points to a short to ground, open circuit, or failed exhaust VVT solenoid.
Common Causes
35%
Faulty exhaust camshaft position actuator solenoid (VVT solenoid)
30%
Damaged wiring or connector at exhaust VVT solenoid
20%
Corrosion in electrical connector terminals
10%
Low oil level or wrong oil viscosity affecting solenoid
5%
ECM internal fault
Diagnostic Steps
1
Step 1: Check engine oil level and condition; ensure proper grade oil is used per manufacturer specs
2
Step 2: Inspect exhaust VVT solenoid connector on Bank 2 for damage, corrosion, or oil contamination
3
Step 3: Disconnect solenoid and measure resistance (typically 6-12 ohms); check for open or short
4
Step 4: Test wiring from ECM to solenoid for continuity, shorts to ground, and voltage supply
5
Step 5: If components and wiring test within specs, perform ECM output driver test or consider ECM replacement
Estimated Repair Cost
$150 - $450
Parts + labor, varies by vehicle and location
The ECM has detected a lower than expected voltage or resistance in the exhaust camshaft position actuator control circuit for Bank 2. This points to a short to ground, open circuit, or failed exhaust VVT solenoid.
The most common cause of P2094 (B Camshaft Position Actuator Control Circuit Low Bank 2) is: Faulty exhaust camshaft position actuator solenoid (VVT solenoid)
Typical repair costs for P2094 range from $150 to $450, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle can be driven cautiously but will experience reduced performance and fuel economy. Prolonged operation may lead to engine damage or increased emissions.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2094 to identify the root cause.
