P2013Intake Manifold Runner Control Circuit High (Bank 2)

Q: What does code P2013 mean?

Intake Manifold Runner Control Circuit High (Bank 2). P2013 is a generic powertrain code indicating that the engine control module has detected a high voltage condition on the intake manifold runner control circuit for bank 2. The intake manifold runner control system uses a motor or solenoid to adjust airflow through the intake runners, and a high voltage reading typically means the circuit is open, shorted to power, or the actuator has failed.

Symptoms you may notice

Illumination of the check engine light, often with no other noticeable symptoms
Rough idle or stumbling, especially when the engine is cold
Reduced engine performance or hesitation during acceleration
Poor fuel economy due to incorrect airflow tuning
In some cases, a noticeable loss of power at higher RPMs

Common causes, most likely first

Faulty intake manifold runner control actuator or solenoid on bank 2
Open or damaged wiring in the intake manifold runner control circuit
Corroded or loose electrical connector at the actuator or ECM
Short to voltage in the control circuit
Failed engine control module (rare but possible)
Carbon buildup or mechanical binding in the intake manifold runner mechanism

How to diagnose and fix it

Use a scan tool to verify the code and check for any related codes in the intake manifold runner control system
Visually inspect the actuator, wiring, and connectors for damage, corrosion, or loose pins
Measure resistance of the actuator and compare to manufacturer specifications
Check for voltage on the control circuit with the key on and engine off to detect a short to power
Test the circuit for continuity and shorts to ground using a multimeter
If the actuator is faulty, replace it and clear the code
If wiring is damaged, repair or replace the affected section and retest

What the high voltage reading really means

A high voltage code often results from an open circuit rather than a short, so check for broken wires or disconnected plugs first.
The intake manifold runner control system may be vacuum-operated on some engines, so a stuck actuator can cause a high voltage signal without an electrical fault.
Carbon buildup on the intake runner flaps can cause mechanical binding that mimics an electrical failure, so inspect the mechanical components as well.
This code is sometimes set by a failing ECM driver, but that is rare and should only be suspected after all other possibilities are ruled out.
Incorrect readings can occur if the battery voltage is low or unstable, so ensure the charging system is healthy before diagnosing.

Can I keep driving with P2013?

You can usually continue driving with this code, but expect reduced engine performance and fuel economy. Avoid aggressive acceleration or heavy loads until the fault is repaired, as prolonged driving may cause further damage to the intake system or catalytic converter.
