The Check engine light came on last night and I scanned the ECU and it came up with
========================
P0128
Raw code: 0128
ECU: Engine control unit
Status: Confirmed
OBDII: Coolant thermostat - coolant temperature below thermostat regulating temperature=================


How much does it cost to replace this part on average?

Thanks in advance

 

Well to answer the cost, I just had it replaced by my Indy shop

$800
$600 Labor
$230 Parts

That sound about right?

 

SIGH I got a quote from another shop for $587
