What Does P2676 Mean?
The air cleaner inlet control circuit voltage is lower than expected. This indicates a short to ground or resistance issue in the control circuit preventing proper actuator operation.
Common Causes
40%
Short to ground in control circuit wiring
25%
Failed air inlet control actuator with internal short
20%
Corroded or water-damaged connector causing short
10%
Chafed wiring harness rubbing against chassis or engine
5%
Failed ECM driver circuit pulling voltage low
Diagnostic Steps
1
Step 1: Disconnect air inlet control actuator and measure resistance; compare to specifications
2
Step 2: Check for voltage at actuator connector with key on; should read battery voltage
3
Step 3: Inspect wiring harness for chafing, pinching, or damage along entire route
4
Step 4: Perform resistance test from control circuit to ground with actuator disconnected
5
Step 5: If wiring tests good, replace actuator; if short remains, test ECM driver circuit
Estimated Repair Cost
$150 - $500
Parts + labor, varies by vehicle and location
The air cleaner inlet control circuit voltage is lower than expected. This indicates a short to ground or resistance issue in the control circuit preventing proper actuator operation.
The most common cause of P2676 (Air Cleaner Inlet Control Circuit Low) is: Short to ground in control circuit wiring
Typical repair costs for P2676 range from $150 to $500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
No safety risk. Vehicle can be driven normally with possible minor reduction in cold-weather driveability.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2676 to identify the root cause.
