I went to advanced auto w/ the ses on. they pulled 1126, and it said "manufacturers air and fuel metering" or something along those lines. I searched the org, and the code says-- P1126 - Throttle Control Motor Relay Circuit Open and also this--P1126 - (2000-2001) Thermostat Function. I am not a great car guy, so I dont know if anything is related out of these three. I am looking for a solution to this prob, so anyone w/ any advice please help, it would be greatly appreciated. thanks

 

DTC1126

Engine coolant temperature has not risen enough to open the thermostat
even though the engine has run long enough.
This is due to a leak in the seal or the thermostat stuck open.
Malfunction is detected when the engine coolant temperature does
not reach to specified temperature even though the engine has run
long enough.

Does your temp gauge read in the normal range while crusing?
