EGR-TCV

- This valve is used on some engines in the vacuum line to the EGR valve.
- The valve is closed below 61° F to block the vacuum to the EGR valve permitting better cold engine operation.
- The valve is open above 76° F permitting normal EGR operation.
- If vacuum is present at the EGR valve when engine coolant temperature is below 61° F, or there is no vacuum present when temperature is above 76° F, replace the valve.

NOTE: Refer to the number stamped on the base of the switch or valve for calibrated switching or activation temperatures.
