What Does P1514 Mean?
The PCM has detected that the secondary intake manifold changeover valve circuit (Valve 2) is shorted to ground. This prevents proper voltage supply and control of the valve actuator.
Common Causes
45%
Wiring harness chafing or rubbing against chassis ground
30%
Failed IMRC solenoid 2 with internal short to ground
15%
Connector contamination or corrosion causing ground path
10%
Pinched wire during previous service or repair work
Diagnostic Steps
1
Step 1: Disconnect secondary IMRC valve and measure resistance to ground on control wire (should be infinite/open circuit)
2
Step 2: Inspect wiring harness routing for contact with sharp edges, chassis, or engine components
3
Step 3: Check connector for moisture, corrosion, or debris causing ground path
4
Step 4: Test solenoid resistance and check for continuity between solenoid case and control terminal
5
Step 5: Perform insulation resistance test on harness if visual inspection reveals no obvious damage
Estimated Repair Cost
$150 - $550
Parts + labor, varies by vehicle and location
The PCM has detected that the secondary intake manifold changeover valve circuit (Valve 2) is shorted to ground. This prevents proper voltage supply and control of the valve actuator.
The most common cause of P1514 (Intake Manifold Changeover Valve2 circuit Short to ground) is: Wiring harness chafing or rubbing against chassis ground
Typical repair costs for P1514 range from $150 to $550, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to operate. May notice slight reduction in power delivery or fuel economy at specific engine speeds.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1514 to identify the root cause.
