P0027 P0027 Exhaust Valve Control Solenoid Circuit Range/Performance
What P0027 means for you
Both sources align on a medium severity.
Symptoms
- The primary indication of a P0027 code is the illumination of the check engine light.
- This issue may lead to higher fuel consumption due to the malfunctioning variable valve lift system.
- Drivers might experience reduced acceleration and overall engine power at certain speeds.
- More severe symptoms can include engine misfires and an uneven idle.
- Overall engine performance may be noticeably diminished.
Common causes
- A frequent cause of the P0027 code is a short circuit or an open circuit in the wiring between the exhaust solenoid and the engine control module (ECM).
- Another potential issue is a failing powertrain control module (PCM), which oversees engine operations.
- Insufficient engine oil levels or contaminated oil can also trigger this code.
- Additionally, a faulty connector can result in a loss of ground contact.
- The Exhaust Valve Control Solenoid regulates the exhaust valve's position using oil pressure and electrical signals, and is crucial for vehicles equipped with variable valve timing (VVT).
- If the PCM detects a problem with the signal from the Exhaust Control Solenoid, it will trigger the P0027 code.

The P0027 code indicates that the exhaust valve control solenoid for bank 1 is either responding too slowly or not at all. This solenoid is part of the variable valve lift system, which optimizes engine performance by adjusting the exhaust valve's operation based on engine demands. If the solenoid fails to manage the valve correctly, it can lead to performance issues and increased emissions.
Frequently asked questions
It is not advisable to drive with a P0027 code, as it can lead to rough engine performance and potential damage.
Repair costs for a P0027 code can vary, but typically range from $100 to $300, depending on the underlying issue.
Symptoms of a P0027 code include a check engine light, decreased engine performance, and increased fuel consumption.
Common causes of a P0027 code include wiring issues, a malfunctioning PCM, low or dirty engine oil, and faulty connectors.
