What Does P2093 Mean?
The ECM has detected a higher than expected voltage in the intake camshaft position actuator control circuit for Bank 2. This typically indicates a short to power or an internal solenoid failure causing excessive current draw.
Common Causes
40%
Faulty intake camshaft position actuator solenoid (VVT solenoid)
25%
Wiring harness short to power (12V)
20%
Corroded or oil-contaminated electrical connector
10%
Failed ECM driver circuit (rare)
5%
Chafed wiring rubbing against hot or sharp components
Diagnostic Steps
1
Step 1: Visually inspect wiring harness for damage, especially near hot exhaust components or moving parts
2
Step 2: Disconnect VVT solenoid and check for oil contamination in connector; clean and dry if necessary
3
Step 3: With solenoid disconnected, check for voltage at harness side; should be 0V with key on (not powered constantly)
4
Step 4: Measure VVT solenoid resistance; replace if shorted (near 0 ohms) or out of specification
5
Step 5: Check for proper ECM ground connections and verify no chafed wires creating short to power
Estimated Repair Cost
$150 - $500
Parts + labor, varies by vehicle and location
The ECM has detected a higher than expected voltage in the intake camshaft position actuator control circuit for Bank 2. This typically indicates a short to power or an internal solenoid failure causing excessive current draw.
The most common cause of P2093 (A Camshaft Position Actuator Control Circuit High Bank 2) is: Faulty intake camshaft position actuator solenoid (VVT solenoid)
Typical repair costs for P2093 range from $150 to $500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to drive short distances but engine performance will be degraded. May cause catalytic converter damage if driven extensively due to improper combustion timing.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2093 to identify the root cause.
