The check engine symbol appeared on the dash board, and a repair shop read the code as PO128. Is it something to do with the temperature sender? Where is the temp. sender? Is there more than one? The car is a 2007 SE 2.0 PZEV manual trans. How is the sender(s) tested?
I used the procedure that uses the odometer to read coolant temp. while the engine runs. The temp. never went over 72C-162F at 70 mph in 55F weather. At 55mph the temp. is 70C-158F. Is the thermostat stuck open? This is a Calif. PZEV Duratec 2.0. Which, w/ or w/out the wire, thermostat does this engine have?
Tried using the VIN CODE on the NAPA and Ford parts web sites, and the Ford dealer to pinpoint the thermostat with or without the sensor. No joy. But now I know what they both look like and will try again with the mirror and flashlight. Thanks for all your help
If it helps,you're not the first that had to look at the part to tell which was used.
