Code P2013 indicates that the engine control module has detected a voltage reading on the Bank 2 intake manifold runner control circuit that exceeds the calibrated threshold. This typically signifies an open circuit, a short to voltage, or a faulty actuator solenoid on the side of the engine opposite cylinder number one. The code sets when the expected low-side driver voltage is not present during operation or testing.
The electromagnetic winding inside the runner control solenoid may be open, shorted, or internally damaged, preventing proper current draw and causing the circuit voltage to remain high.
The wire harness connecting the PCM to the Bank 2 runner control solenoid may have an open circuit, or the signal wire may be shorted to voltage or adjacent power feeds due to chafing, pinching, or rodent damage.
Moisture intrusion or oxidation within the solenoid's electrical connector can increase resistance or create an open circuit, leading to a high voltage reading at the PCM monitor.
Carbon buildup or physical damage causing the intake manifold runner valves to seize can overload or damage the actuator, potentially altering circuit resistance and triggering the fault.
In uncommon cases, the low-side driver inside the engine control module may fail to ground the circuit properly, though this should only be considered after verifying wiring and actuator integrity.
Short trips are generally possible, but performance may suffer and the engine could stall; prolonged operation risks catalyst damage if the air-fuel ratio is affected, so repair should be scheduled promptly.
No, that is usually incorrect. The fault almost always lies with the solenoid, wiring, or connector; PCM failure is rare and should only be considered after exhaustive testing proves the circuit and component are sound.
Bank 2 is the cylinder bank opposite Bank 1; on most V-configured engines, Bank 1 contains cylinder number one, making Bank 2 the opposite head. Consult a service manual for your specific engine layout if uncertain.
If the fault was intermittent (such as moisture in a connector), the code may clear after several successful driving cycles, but persistent mechanical or electrical failures will require repair before the light stays off.
