Details of the p0027 OBD Code
Fault code P0027 relates to an issue with the exhaust valve control solenoid circuit in bank 1.
OBD code P0027 means that the ECM has detected a malfunction in the Exhaust Valve Control Solenoid Circuit for Bank 1. This code is triggered when the ECM detects an incorrect voltage signal from the exhaust valve control solenoid for bank 1. The exhaust valve control solenoid is responsible for controlling the flow of oil to the variable valve timing system, which helps optimize engine performance and fuel efficiency.
When the ECM detects an issue with the exhaust valve control solenoid circuit, it illuminates the Check Engine Light and stores the P0027 fault code.
Mechanic’s Tech Notes
Code P0027 indicates a malfunction in the exhaust valve control solenoid circuit for bank 1.
OBDII code P0027 indicates an issue with the Exhaust Valve Control Solenoid Circuit Range/Performance Bank 1. To diagnose, use a voltmeter to check the solenoid’s power and ground circuits for proper voltage and continuity.
Scan tools can help monitor the solenoid’s operation and response to commands.
Visually inspect the wiring harness and connectors for any damage, corrosion, or loose connections.
Ensure connector pins are intact and not bent.
If no visible issues are found, consider testing the solenoid itself for proper operation.
Clear the code after any repairs and monitor for recurrence.
