Summary
  • The powertrain control module (PCM) will log a P0080 trouble code when it detects an abnormal signal from the exhaust control solenoid in bank 1.
  • Aside from a damaged exhaust valve control solenoid, low engine oil levels, and wiring issues can trigger this trouble code.
  • If this code is present, your vehicle might exhibit symptoms like poor engine performance and decreased fuel economy.

An OBD-II code is designed to inform you about potential issues in your vehicle. But to successfully resolve it, you must first know what the logged code entails. If you’re having trouble figuring out what code P0080 means, you’ve come to the right place.

What Does the P0080 Code Mean?

Diagnostic trouble code (DTC) P0080 stands for “Exhaust Valve Control Solenoid Circuit High Bank 1.” It is set when the powertrain control module (PCM) perceives a potential problem with the signal from the exhaust control solenoid.

To be more specific, this code may be logged when the PCM detects that the signal and voltage from the exhaust control solenoid in Bank 1 is above specification. Bank 1 refers to the side of the engine where cylinder #1 is located, while the exhaust valve control solenoid can be found on the exhaust manifold side of the cylinder head.

Code P0080 may register if your PCM detects a potential problem with the signal from the exhaust control solenoid.

On vehicles equipped with variable valve timing (VVT), the PCM can adjust the camshaft position, altering the timing of the exhaust and/or intake valves. The PCM controls the camshaft position by regulating oil flow (via a solenoid) to the actuator(s) mounted on the end of the camshaft(s).

The control solenoid that regulates oil flow is activated by a pulse width modulated signal (PWM) from the PCM. If the PCM determines there is an issue with the signal from the exhaust control solenoid in bank 1, it will log error code P0080.

Depending on the severity, other trouble codes may also be logged. Code P0080 is similar to P0078, P0079, and P0027.

Read our brief explanation about what the control solenoid does before proceeding with any DIY repair for P0080.

Note: The definition of code P0080 may be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.

Extremely low engine oil level can cause code P0080.

What are the Possible Causes of the P0080 Code?

P0080 is a generic code, so it can have several causes. Here are the most common:

  • Faulty exhaust valve control solenoid
  • Extremely low engine oil level
  • Circuit issue, such as damaged wires or poor connections
  • Failing PCM or software in need of an update

What are the Common Symptoms of the P0080 Code?

You may notice the following symptoms if you drive a vehicle with a stored P0080 trouble code:

How to Diagnose the P0080 Code

To avoid the possibility of engine damage, code P0080 should be resolved immediately. Because it has many possible triggers, diagnosing this code can be tricky.

Always follow the diagnostic procedure specified by your vehicle’s manufacturer because the process may vary per model. The steps for diagnosing a code P0080 on a Mitsubishi, for instance, may be different from testing for a code P0080 on a Toyota.

Refer to a repair manual for the appropriate diagnostic strategy. If you’re not familiar with auto repair, it would be best to leave the job to a mechanic.

How to Fix the P0080 Code

P0080 may share similar triggers and symptoms with other trouble codes. However, this does not mean it also shares the same fixes. All vehicles are different, so you should always refer to the factory repair information specific to your car before trying DIY repairs.

Code P0080 is a complicated code, so you should always refer to a repair manual or repair database before attempting any fixes. If you aren’t confident in your automotive repair skills, it may be best to enlist the help of a professional.
