Code 1005

COMPONENT DESCRIPTION
The EGRC-solenoid valve responds to signals from the ECM. When the ECM sends an ON (ground) signal, the coil in the solenoid valve is energized. The vacuum signal passes through the solenoid valve. The signal then reaches the EGR valve. When the ECM sends an OFF signal, a plunger will then move to cut the vacuum signal from the intake manifold collector to the EGR valve.

CONSULT Reference Value in Data Monitor Mode
Specification data are reference values.

ECM Terminals and Reference Value
