What Does P1513 Mean?
The PCM has detected that the secondary intake manifold changeover valve circuit (Valve 2) is shorted to battery positive voltage. This affects variable intake systems with multiple control valves.
Common Causes
40%
Wiring harness damage causing short to power source
35%
Failed secondary IMRC solenoid with internal short circuit
15%
Corroded or damaged connector with terminal cross-contact
10%
Moisture intrusion in connector causing voltage leak
Diagnostic Steps
1
Step 1: Disconnect secondary IMRC valve connector and verify if fault is present with valve isolated
2
Step 2: Measure voltage on harness side control wire with key on (should read 0V when disconnected)
3
Step 3: Inspect wiring between PCM and valve for chafing, melting, or contact with power sources
4
Step 4: Check connector for corrosion, moisture, or terminal damage causing short
5
Step 5: Test solenoid resistance in isolation to confirm internal condition
Estimated Repair Cost
$175 - $575
Parts + labor, varies by vehicle and location
The PCM has detected that the secondary intake manifold changeover valve circuit (Valve 2) is shorted to battery positive voltage. This affects variable intake systems with multiple control valves.
The most common cause of P1513 (Intake Manifold Changeover Valve2 circuit Short to B+) is: Wiring harness damage causing short to power source
Typical repair costs for P1513 range from $175 to $575, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is safe to drive. May experience minor performance loss or reduced efficiency in specific RPM ranges.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1513 to identify the root cause.
