P1513 — Intake Manifold Runner Control Stuck Open (Bank 1)

Severity: low Safe to drive

What P1513 means

Many engines have intake manifold runner flaps that change the length or size of the intake passages depending on engine speed and load. The engine control unit commands the actuator and uses a position sensor to confirm the flaps moved. P1513 means the bank 1 runners stay open when they should have changed position. The exact definition varies by manufacturer, so confirm it for your brand.

Symptoms

  • Check engine light on
  • Reduced power at high RPM
  • Rough or unstable idle
  • Worse fuel economy
  • Possible rattle or whistle near the intake manifold

Possible causes

  1. Broken or disconnected actuator linkage
  2. Failed electric motor or vacuum actuator
  3. Broken flap return spring
  4. Carbon buildup or seized flaps
  5. Wiring or connector damage, corrosion or shorts
  6. Faulty runner position sensor
  7. Vacuum leak or no vacuum supply (on vacuum-operated systems)

How to diagnose

  1. Scan all codes and freeze frame data and look for related intake faults
  2. Inspect the actuator connector and harness for damage, corrosion or chafing
  3. Check vacuum hoses and the control solenoid if the system is vacuum-operated
  4. Use a scan tool active test to command the actuator and watch whether the linkage moves
  5. Remove the actuator and move the flaps by hand to look for binding, carbon or a broken spring
  6. Test power, ground and position sensor signal with a multimeter using the wiring diagram
  7. Clear the code after repair and confirm it does not return

Common fixes

  • Replace the linkage, lever or plastic actuator parts
  • Replace the electric or vacuum actuator
  • Clean carbon from the flaps and runners
  • Repair the wiring or connector
  • Replace the intake manifold assembly if the flaps are not sold separately

Questions and answers

What does P1513 mean?

Generally the engine computer sees the bank 1 intake manifold runner flaps stuck open. Some brands define it differently, so verify it for your vehicle.

Can I drive with P1513?

Usually yes, but you may lose power at high RPM and some fuel economy. Have it diagnosed soon.

How do I fix P1513?

Inspect the wiring, actuator and linkage, then check that the flaps move freely. Replacing the actuator, linkage or manifold is the most common repair.

This is general information about the code. The meaning can differ between makes and models: a scan tool and the repair manual for your car will show the exact cause.
