P1299 Overtemperature protection active
Has anyone had experience with this code? Nephew's 2001 Grand Marquis overheated due to coolant inlet pipe breaking on the rear of the intake manifold. This code came up, which is understandable. He said they drove the car about 2 miles from home w temp light on and parked the car. He said it didn't shut off on its own or lock up. I replaced the manifold w a used manifold from a 2001 Crown Victoria, everything is reconnected properly, replaced thermostat, TSU, has good fuel flow, battery reads correct V, added fresh coolant, but the car won't start. After several attempts to start, the starter solenoid energizes, but the motor turned over on only one try and has not turned over any more. I thought the motor may have seized, but it wouldn't have attempted to start (turn over) if that was the case. I disconnected the battery for 5 minutes, reconnected and erased stored codes w my ODB II scanner and tried to restart again w same results. Then I put the car in neutral, and attempted to turn the motor over manually, using a socket and ratchet on the flywheel nut. Wouldn't budge in either direction. My next step is to drop the oil pan and take a look at the bottom end. The only thing I could find in research is that the PCM may be damaged, but I would think if that were the case, that the motor would at least turn over and not just clunk from the starter - am I right?
I hope someone can give me a cyber hand with this, and i hope the motor isn't seized. |

Carefully take out each plug on whole motor. If it turns over by hand. You have a blown head gasket or a cracked head.
