How does the VTEC system control the rocker arm?
The VTEC system controls the rocker arm control solenoid through the powertrain control module (PCM). The PCM uses the rocker arm oil pressure switch to monitor and verify the oil pressure so the variable timing mechanism can be properly activated.
The VTEC system controls the rocker arm control solenoid through the powertrain control module (PCM). The PCM uses the rocker arm oil pressure switch to monitor and verify the oil pressure so the variable timing mechanism can be properly activated.
What does the rocker arm control solenoid do?
In vehicles equipped with VTEC, the rocker arm control solenoid supplies hydraulic pressure to the variable timing and lift mechanism. This allows the VTEC system to adjust valve timing and lift as needed.
When is a rocker arm actuator stuck on?
If the PCM detects a level of resistance from the rocker arm actuator circuit indicating that it is stuck in the on (valve open) position, a code P2647 will be stored and a malfunction indicator lamp may be illuminated. What are the common causes of code P2647? What are the symptoms of code P2647? How do you troubleshoot code P2647?
What is the OBD code for the rocker arm?
If the PCM does not receive the correct voltage signal back from the rocker arm oil pressure switch, it may set code P2646. The “A” in this OBD code’s definition indicates the intake camshaft.
In vehicles equipped with VTEC, the rocker arm control solenoid supplies hydraulic pressure to the variable timing and lift mechanism. This allows the VTEC system to adjust valve timing and lift as needed.
