P200A Code: Intake Manifold Runner Performance (Bank 1)

Code P200A is one of many trouble codes that may be logged and retrieved from the OBD system. Here is some basic information that may help you understand what getting this code may mean for your vehicle.

What Does the P200A Code Mean?

Diagnostic trouble code (DTC) P200A stands for “Intake Manifold Runner Performance (Bank 1).” This code is logged when the powertrain control module (PCM) has detected a problem with the intake manifold runner control (IMRC) system. This code is also logged when the intake manifold runner does not operate as it should.

Pro Tip: A “performance” code means the command was given for the runner controls to change but other inputs indicated they didn’t.

The IMRC system is designed to regulate engine air intake. Airflow is restricted at lower engine RPM levels to reduce exhaust emissions. At higher engine RPM levels, the IMRC flaps create swirling effects to optimize fuel atomization and maximize engine performance. The PCM uses input data from numerous engine sensors to determine the desired degree to which IMRC system components should be requested. If the PCM detects that the IMRC system can’t be controlled effectively, code P200A will be stored.

Depending on the severity of the problem, related error codes may also be stored with this DTC. Code P200A is very similar to P200B.

Note: The definition of code P200A may be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.

What are the Common Causes of the P200A Code?

P200A is a generic code, so it can have several triggers. Here are the most common:

• Damaged IMRC, flaps, linkage or bushings
• Faulty IMRC vacuum supply
• Open or shorted IMRC circuits or connectors
• Bad IMRC sensor
• PCM failure
• Faulty IMRC actuator

What are the Common Symptoms of the P200A Code?

You may notice the following symptoms if you drive a vehicle that has set a P200A trouble code:

• Malfunction indicator lamp may be illuminated
• Poor fuel efficiency
• Poor engine performance
• Hesitation when accelerating
• Stumbling at idle
