Was bedeutet der Fehlercode?

The bypass valve solenoid is driven by the engine control module (ECM) and is used to regulate engine temperature more efficiently. When the solenoid is activated and the signal reads too low, the code is set. The fault may come from a signal wire shorted to ground, a damaged solenoid, a damaged connector or the engine control module.

Mögliche Ursachen

Signal wire shorted to ground
Damaged solenoid
Damaged connector
Damaged engine control module (ECM)

Was Sie tun können

1Check the connector at the solenoid for damage and loose contacts
2Use a multimeter to check that the signal wire to the solenoid has no contact with ground
3Check the wire for chafing that could touch the body earth
4With a diagnostic tool, activate the solenoid to test it
5If nothing is found, have a workshop decide whether the solenoid or the engine control module is damaged
