What Does P2282 Mean?
The PCM has detected an unmetered air leak between the throttle body and the intake valves. This vacuum leak creates an imbalance in the air-fuel mixture that cannot be compensated by the fuel trim system.
Common Causes
35%
Deteriorated or cracked intake manifold gaskets
25%
Vacuum hose disconnected, cracked, or deteriorated
20%
Faulty or leaking PCV valve or system components
12%
Cracked or warped intake manifold
8%
Leaking throttle body gasket or mounting surface
Diagnostic Steps
1
Step 1: Visually inspect all vacuum hoses for cracks, disconnections, or deterioration
2
Step 2: Inspect PCV valve and related hoses for proper connection and condition
3
Step 3: Perform smoke test on intake manifold to identify leak location
4
Step 4: Check intake manifold bolts for proper torque specifications
5
Step 5: Inspect throttle body gasket and mounting surface for leaks
Estimated Repair Cost
$100 - $800
Parts + labor, varies by vehicle and location
The PCM has detected an unmetered air leak between the throttle body and the intake valves. This vacuum leak creates an imbalance in the air-fuel mixture that cannot be compensated by the fuel trim system.
The most common cause of P2282 (Air Leak Between Throttle Body and Intake Valves) is: Deteriorated or cracked intake manifold gaskets
Typical repair costs for P2282 range from $100 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Generally safe to drive but may cause rough idle, stalling, hesitation, and poor performance. Engine damage possible if lean condition persists long-term.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2282 to identify the root cause.
