    Turn key on, push and hold override/chk button. Located next to the starter button. Count the flashes. 2 digit #. So 4 blinks, 1 second delay and 4 more blinks = code # 44

    What do you have pin to pin. Any battery or starter work lately?

    I tested the continuity between the temp control valve and the ecm and there good. Does any know where the wires from the wires go from the low water sensor to I can't find where it terminates

    Low coolant sensor terminates on the Vehicle Interface Harness connector on the right hand lower side of the ECM. Pictures I sent earlier displays that. Other picture lists which spot: Cavity H-3, Wire # 115. Wire #s are printed on wires. They often fade to the point you cannot see.
     
    Rideandrepair Thanks this.
