Error Code P0080: What It Means & What To Do?

<<See All OBD Codes

The P0080 code can be defined as Exhaust Valve Control Solenoid Circuit High Bank 1. The vehicle can have bank 1 or some sometimes bank 2 control solenoids. P0078 and P0079 codes are also related to this trouble code.

The P0080 is a common OBD code which indicates that there is some issue with the bank 1 exhaust valve control solenoid. The engine control module tries to control the variable valve timing and may find out of range value in the exhaust valve control solenoid. This can be an indication that high voltage was present in the circuit.

What causes this problem with the Exhaust Valve Control Solenoid Circuit High (Bank 1)?

• The wiring harness for control solenoid may be opened or shorted
• There can be some failure in the engine control module
• The connector might be loose or may face bad electrical connection
• Failure in the exhaust valve control solenoid

1. Valve Control Solenoid - OBD Error Code P0080 can simply be due to faulty Valve Control Solenoid. Replace old and damage components now!
2. Engine Control Module - OBD Code P0080 can flash if the engine control module is damaged. You must replace it with a brand new one online with us.
3. Variable Valve Timing - Did your mechanic just found out that there is some fault in the Variable Valve Timing? Buy top notch Variable Valve Timing from us at economical prices.

There are some symptoms that are related to the P0080 trouble code. Have a look at them below:

Common Symptoms

• The first and the foremost thing which you will start noticing is the illumination of the check engine light on the dashboard
• The car will be put into the failsafe mode with the engine control module and the variable valve timing system may get disabled
• When the variable valve timing is disabled, then you may experience bad vehicle acceleration and worse than normal fuel economy may be noticed
• These symptoms will be in effect until the code is resolved.

• The engine control module should be replaced
• The wiring harness should be repaired or replaced
• Exhaust valve control solenoid bank 1 should be replaced
• The connection issues or connectors should be replaced

There is no need to get strained if your OBD Code is still flashing up as we are always here at your service. Have a look at our superior variety of PCM, body control module, ecu programming and many more. Now all your problems would vanish within no time.

The DTC refers to a circuit problem and that’s why you must use a DVOM to diagnose the problem. Your full attention should be towards the circuit between the ECM and the VVT solenoid valve, as well as the solenoid valve itself

• The first and the foremost thing which you should do is to hook up a scan tool to the OBD2 port and verify any codes, there may be more than one code present.
• There will be associated freeze frame data with every code; this information would tell you the vehicle and engine speed, coolant temp, engine temperature, and other information.
• Then you should clear up the code and later take the vehicle on the road test duplicating the operating conditions from the freeze frame data.
• If the Check Engine Light is still illuminating on the dashboard then a visual inspection should be carefully performed, looking for any damage to the solenoid circuit connectors, wiring, and solenoid itself.
• Once the visual inspection has been performed then the technician will observe the live data stream on an advanced scan tool, looking at the exhaust valve control solenoid performance under various different conditions.
• If the solenoid passes the test then after that you must test the engine control module. Each manufacturer has its own specific testing procedure which should be properly followed.

Common Mistakes When Diagnosing the P0080 Code

The P0080 is a trouble code which is very easy to diagnose. The most common cause behind the appearance of this code is solenoid failing. But you must keep this thing in mind that you do not skip any step for getting this error code repaired.
