Simulated PCM Solenoid Activation

To further diagnose solenoid, ensure PCM and related circuits are capable of operating solenoid. When test procedure requires simulated PCM solenoid activation, check function of appropriate solenoid. Solenoid should function as follows.

• BANK/INJ  Solenoid should activate during cranking and while engine is running.
• CANP  With engine temperature more than 140°F (60°C), solenoid should activate during vehicle cruise or acceleration.
• EGRC  With engine temperature more than 140°F (60°C), solenoid should activate at normal driving (cruising).
• EGRV  With engine temperature more than 140°F (60°C), solenoid should activate during idle, deceleration or at wide open throttle.
• EVR  With engine temperature more than 158°F (70°C), solenoid should activate when engine speed is less than 1500 RPM.
• FPRC  On 2.0L A/T, coolant temperature more than 190°F (90°C) and intake air temperature more than 68°F (20°C). On all models, solenoid should activate with engine speed less than 1500 RPM and remain activated for 2 minutes after engine is started.
• HSIA  Solenoid should activate when engine speed is less than 5000 RPM.
• IAC  Solenoid should activate during engine cranking and running.
• VRIS  Solenoid should activate with engine at low speed.
