P2013 – Intake Manifold Runner Control Circuit High (Bank 2)

Code Urgency and Severity

The P2013 code indicates an issue with the intake manifold runner control (IMRC) system on bank 2 of the engine. While it's usually safe to drive with this code, it's best to diagnose and repair it promptly to prevent engine damage and performance issues.

In our workshop, we've noticed that the P2013 code tends to pop up more frequently on European cars compared to American or Asian makes. Just last week, we had a BMW 5-series and an Audi A6 come in with this code, both experiencing reduced engine performance and rough idling. After diagnosing the issue, we found that the intake manifold runner control actuators were stuck on both vehicles, likely due to carbon buildup. We've also seen this code on a handful of Volkswagen and Mercedes models over the past few months. While it's not exclusive to European brands, it seems to be more prevalent on these vehicles, possibly due to their complex intake manifold designs and strict emissions control systems. In comparison, we rarely see P2013 on Japanese or American vehicles that come through our shop.

If you notice severe symptoms like major power loss, rough idling, or stalling, stop driving immediately and have the vehicle towed to a mechanic for inspection.

  1. Bank 2 IMRC actuator
  2. Bank 2 IMRC position sensor
  3. Powertrain Control Module (PCM)
  4. Related vacuum lines and wiring

The IMRC system optimizes airflow by adjusting intake manifold runner length at different RPMs. The actuator controls the runner flaps, while the position sensor gives feedback to the PCM.

Typical Causes

Common causes of a P2013 code include:

  1. Defective bank 2 IMRC actuator solenoid
  2. Damaged or stuck bank 2 intake manifold runner flaps
  3. Faulty bank 2 IMRC position sensor
  4. Vacuum leaks or blockages
  5. Wiring problems (opens, shorts)
  6. IMRC flap or intake manifold carbon buildup
  7. Bad PCM (rare)

Diagnostic Process

To diagnose a P2013 code:

  1. Scan for codes and record freeze frame data.
  2. Visually check IMRC wiring and connectors.
  3. Inspect for IMRC vacuum line leaks/restrictions.
  4. Test IMRC actuator and sensor resistance/continuity.
  5. Monitor live IMRC data while testing the actuator.
  6. Check for binding, sticking, or dirty intake manifold runner flaps.
  7. If everything else checks out, suspect a faulty PCM.

Repair Options and Costs

Fixes for a P2013 code depend on the diagnosed root cause:

  1. IMRC actuator solenoid (bank 2) replacement: $150-$300
  2. Intake manifold runner flap cleaning/replacement: $200-$600
  3. IMRC position sensor replacement: $100-$200
  4. Vacuum leak repair or line replacement: $20-$100
  5. Wiring issue repairs: $50-$200
  6. Intake manifold carbon cleaning: $150-$400
  7. PCM replacement (uncommon): $500-$1,500

Prevention Tips

To help prevent a P2013 code from occurring:

  1. Do scheduled maintenance like air filter and spark plug changes.
  2. Promptly fix any vacuum leaks to protect the IMRC system.
  3. Use quality fuel and additives to reduce carbon buildup.
  4. Address related codes quickly to prevent compounding problems.

Associated Codes

By properly understanding and repairing a P2013 code when it appears, engineers and mechanics can restore optimal engine performance. Consult the manufacturer's specific diagnostic and repair information for the most accurate troubleshooting and fix procedures.

Frequently Asked Questions About P2013 Code

What does the P2013 OBD-II code mean?

The P2013 code indicates that the Powertrain Control Module (PCM) has detected a problem with the Intake Manifold Runner Control (IMRC) circuit on bank 2 of the engine. Specifically, it means the voltage in the circuit is reading higher than expected.

What are the common symptoms of a P2013 code?

Common symptoms include:

Is it safe to drive with a P2013 code?

While it’s generally safe to drive short distances with a P2013 code, it’s best to diagnose and repair the issue promptly to prevent potential engine damage and restore performance. If you experience severe symptoms like significant power loss or stalling, do not continue driving.

What are the typical causes of a P2013 code?

Typical causes include:

How do you diagnose a P2013 code?

Diagnosis involves these key steps:

  1. Scan for codes and record freeze frame data
  2. Visually inspect IMRC wiring and connectors
  3. Check for vacuum leaks or blockages
  4. Test IMRC actuator and sensor resistance/continuity
  5. Monitor live IMRC data while testing the actuator
  6. Inspect runner flaps for binding, sticking, or carbon
  7. If no other causes found, suspect a faulty PCM

What parts are involved with a P2013 code?

The main components involved are:

How much does it cost to fix a P2013 code?

Repair costs depend on the root cause. Estimates for common fixes include:

Can a P2013 code clear itself?

While a P2013 code may clear itself if the condition was temporary or intermittent, it will likely reappear if the underlying problem is not fixed. The code needs to be properly diagnosed and the root cause repaired to prevent it from recurring.

How do you clear a P2013 code?

An OBD-II scanner is the safest way to clear the code from the PCM’s memory after repairs are complete. Disconnecting the battery may also clear the code, but this method is not recommended as it can reset other systems and erase valuable diagnostic data.

Can low oil cause a P2013 code?

No, low engine oil level will not directly cause a P2013 code, as this code is related to the intake manifold runner control system. However, low oil can cause engine performance issues and trigger other codes.

Can a vacuum leak cause a P2013 code?

Yes, vacuum leaks in the IMRC system can cause incorrect runner flap positioning and trigger a P2013 code. Technicians should always inspect the vacuum lines and connections when diagnosing this code.

Can a bad O2 sensor cause a P2013 code?

No, a failing oxygen sensor will not directly trigger a P2013 code, as O2 sensors are not part of the IMRC system. However, O2 sensor issues can cause drivability problems similar to a P2013 code.

Can a bad MAF sensor cause a P2013 code?

No, a malfunctioning mass airflow (MAF) sensor does not directly cause a P2013 code. The MAF sensor measures air entering the engine, while the P2013 code relates to the intake manifold runner control after the MAF. However, a faulty MAF can mimic P2013 symptoms.

Can a bad catalytic converter cause a P2013 code?

No, a failing catalytic converter will not trigger a P2013 code, as the catalytic converter is located in the exhaust system, while the P2013 code deals with the intake system. However, catalytic converter problems can cause similar performance issues.

Can a bad ECM cause a P2013 code?

Yes, although rare, a faulty PCM (ECM) can cause a P2013 code if it incorrectly detects a problem with the IMRC circuit. The PCM controls the IMRC system, so it should be suspected if no other causes are found.

Can a P2013 code cause misfire?

While a P2013 code itself does not cause misfires, the underlying issue (such as vacuum leaks or carbon buildup) can lead to rough running and misfires. Misfires are more often caused by ignition or fuel delivery problems.

Can carbon buildup cause a P2013 code?

Yes, carbon deposits on the intake manifold runner flaps or ports can cause them to stick or bind, triggering a P2013 code. Cleaning the intake manifold and flaps is often necessary when diagnosing this code.

What is the difference between P2013 and P2014?

Both codes relate to the IMRC system, but P2013 indicates a problem with bank 2, while P2014 points to an issue with bank 1. Bank 2 is the side of the engine that does not contain cylinder #1.

Can you drive long distances with a P2013 code?

It’s not advisable to take long trips with an active P2013 code, as the underlying issue can worsen and lead to reduced performance, increased emissions, and potential engine damage. It’s best to resolve the problem before embarking on a long drive.

How often does a P2013 code occur?

The frequency of a P2013 code varies by vehicle make and model. It is more common on vehicles equipped with variable intake manifold runner control systems, such as certain Audi, Volkswagen, Ford, GM, and Hyundai engines. However, any vehicle with an IMRC system can potentially experience a P2013 code. Regular maintenance, including replacing air filters, cleaning intake components, and addressing vacuum leaks, can help prevent this code from occurring.
