Details of the p0028 OBD Code
Fault code P0028 indicates an issue with the intake valve control solenoid for bank 2.
OBD code P0028 means Intake Valve Control Solenoid Circuit Range/Performance Bank 2. This code is triggered when the ECM detects that the intake valve control solenoid for bank 2 is operating outside of the expected range or performance parameters.
The intake valve control solenoid is responsible for controlling the intake valve timing, which can affect engine performance and emissions.
The signal or system involved in this fault code is the intake valve control solenoid circuit for bank 2.
Mechanic’s Tech Notes
Code P0028 indicates a problem with the intake valve control solenoid for bank 2.
To diagnose and fix OBDII code P0028, start by checking the wiring harness and connectors related to the intake valve control solenoid for any damage or corrosion.
Use a voltmeter to test the solenoid’s power and ground connections.
Next, use a scan tool to monitor the solenoid’s operation and response over the vehicle’s network.
If necessary, consider reprogramming the engine control module.
Additionally, inspect the oil level and quality, as low oil levels or dirty oil can trigger this fault code.
If the issue persists, the intake valve control solenoid itself may need to be replaced.
