What Does P3482 Mean?
The PCM has detected that cylinder 11's deactivation or intake valve control system is not performing within expected parameters. The valve timing or deactivation mechanism response is delayed, sluggish, or inconsistent compared to commanded values.
Common Causes
30%
Low or contaminated engine oil affecting hydraulic valve control actuators
25%
Faulty intake valve control solenoid or cylinder deactivation solenoid
20%
Clogged oil passages or screens in valve control mechanism
15%
Worn or damaged intake valve control mechanism or lifter assembly
10%
Wiring harness resistance or intermittent connection issues
Diagnostic Steps
1
Step 1: Check engine oil level, condition, and viscosity; change if needed with manufacturer-specified oil
2
Step 2: Monitor live data showing commanded vs actual valve timing/deactivation status for cylinder 11
3
Step 3: Perform intake valve control solenoid actuation test using scan tool bi-directional controls
4
Step 4: Inspect oil control valve screens for debris or restriction
5
Step 5: Test electrical circuit integrity including voltage drop testing on power and ground circuits
Estimated Repair Cost
$250 - $1,400
Parts + labor, varies by vehicle and location
The PCM has detected that cylinder 11's deactivation or intake valve control system is not performing within expected parameters. The valve timing or deactivation mechanism response is delayed, sluggish, or inconsistent compared to commanded values.
The most common cause of P3482 (Cylinder 11 Deactivation/Intake Valve Control Circuit Performance) is: Low or contaminated engine oil affecting hydraulic valve control actuators
Typical repair costs for P3482 range from $250 to $1,400, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle remains safe to operate but may experience reduced performance, rough idle, and decreased fuel economy. Prolonged operation could lead to engine damage.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P3482 to identify the root cause.
