What Does P2313 Mean?
The PCM detected an abnormally high voltage in the primary control circuit of ignition coil E. This typically indicates an open circuit, poor ground connection, or loss of control signal.
Common Causes
35%
Open circuit in ignition coil E primary wiring or connector
30%
Failed ignition coil E with open primary winding
20%
Corroded or disconnected coil E connector pins
10%
Broken or damaged ground circuit for coil E
5%
PCM internal driver circuit failure (open transistor)
Diagnostic Steps
1
Step 1: Inspect coil E connector for loose, backed-out, or corroded terminals
2
Step 2: Measure primary resistance of coil E; infinite resistance indicates open winding
3
Step 3: Check voltage at coil E primary power supply (should be battery voltage with key on)
4
Step 4: Test continuity of control wire from PCM to coil E with connector disconnected
5
Step 5: Verify ground circuit integrity at coil mounting point and PCM connector
Estimated Repair Cost
$120 - $450
Parts + labor, varies by vehicle and location
The PCM detected an abnormally high voltage in the primary control circuit of ignition coil E. This typically indicates an open circuit, poor ground connection, or loss of control signal.
The most common cause of P2313 (Ignition Coil "E" Primary Control Circuit High) is: Open circuit in ignition coil E primary wiring or connector
Typical repair costs for P2313 range from $120 to $450, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Cylinder E will not fire, causing significant power loss, rough running, and potential catalytic converter damage. Do not drive extended distances.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2313 to identify the root cause.
