P0080 trouble code definition

P0080 is in reference to the bank 1 exhaust valve control solenoid. The vehicle may have a bank 1 and bank 2 control solenoid. This code may be seen in association with P0078 and P0079.

What the P0080 code means

P0080 is a common OBD2 code that is indicating an issue with the bank 1 exhaust valve control solenoid. The ECM has tried to control the variable valve timing and found out of range value in the exhaust valve control solenoid. Specifically this is telling us that high voltage was found in the circuit.

What causes the P0080 code?

A few basic issues can be the cause of P0080, they are as follows:

  • Open or short in wiring harness for control solenoid

  • ECM failure

  • Loose connector or poor electrical connection

  • Failed exhaust valve control solenoid

What are the symptoms of the P0080 code?

There are a few typical symptoms that are associated with the P0080 code:

  • The first one that will be noticed is the ECM will illuminate the Check Engine Light on the dashboard.

  • The ECM will put the car into a failsafe mode and the variable valve timing system will be disabled.

  • When the variable valve timing is disabled poor vehicle acceleration and worse than normal fuel economy may be noticed.

These symptoms will be in effect until the code is resolved.

How does a mechanic diagnose the P0080 code?

  • The first operation performed will be hooking up a scan tool to the OBD2 port and verify any codes, there may be more than one code present.

  • With every code there will be associated freeze frame data, this information tells us vehicle and engine speed, coolant temp, engine temperature, and other information.

  • The code will then be cleared and the vehicle will be taken on a road test duplicating the operating conditions from the freeze frame data.

  • If the Check Engine Light illuminates on the dashboard then a visual inspection will be performed, looking for any damage to the solenoid circuit connectors, wiring, and solenoid itself.

  • After a visual inspection is performed the technician will observe the live data stream on an advanced scan tool, looking at the exhaust valve control solenoid performance under various conditions.

  • If the solenoid passes the test then testing the ECM will be required. Each manufacturer has its own specific testing procedure that must be followed.

Common mistakes when diagnosing the P0080 code

  • P0080 is generally a simple code to diagnose. The most common cause is the solenoid itself failing, but each step must be performed without any skipped to accurately repair this code.

  • This code can be a intermittant code and will only exhibit symptoms randomly, if this occurs the solenoid must not be replaced until it is verified to be faulty.

How serious is the P0080 code?

  • Most people will only noticed the Check Engine Light on the dashboard for felt symptoms.

  • This code will trigger a failsafe in the vehicle and disable the variable valve timing, when this occurs caution must be observed when driving as it affects vehicle acceleration and vehicle fuel economy.

  • As soon as possible this code should be repaired to ensure safe driving. P0080 should not stop the vehicle from driving to a safe location once the code is set.

What repairs can fix the P0080 code?

  • ECM replacement

  • Repair or replacement of wiring harness

  • Exhaust valve control solenoid bank 1 replacement

  • Fix connection issues or connectors

Additional comments for consideration regarding the P0080 code

Most modern cars are equipped with variable valve timing. Variable valve timing or its variants aids in fuel economy and helps vehicle power and acceleration. It is an important system on modern engines.

Some vehicles may have more than one bank of cylinders. Vehicles equipped with V6 engines and V8 engines are examples with a bank 1 and bank 2. Bank one can usually be identified as the left side of the engine from the driver's seat. It can also be found by finding cylinder one and will be located near the exhaust manifold.

A professional level scan tool that allows users to view live data and things such as voltage, ohms, and changes over time in the form of a graph is necessary to properly diagnose P0080. These scan tools allow us to see the data and is especially useful for intermittent sensor issues.
