Trouble Code: P1258 (4.6L V8 VIN 9 Auto)
Engine Metal Over-Temperature Protection
Number of Trips to Set Code: 1
OBD II Monitor Type: CCM Details
Indicators: MIL Details
Trouble Code Conditions:
DTC P0117, P0118 and P0125 not set, Engine started; and the PCM detected the ECT sensor indicated more than 270ºF for 10 seconds. The PCM uses the ECT sensor to detect if the engine is running too hot (when the ECT sensor is over 268ºF). If the engine is overheated, DTC P1258 will set. The PCM will disable 2 groups of four cylinders by turning off the fuel injectors. By switching between the two groups of cylinders, the PCM is able to reduce the temperature of the coolant and lower the temperature.

Possible Causes:
  • Engine cooling system problem (test the cooling fan operation)
  • Engine coolant level is low or the mixture is not correct
  • ECT sensor is out-of-calibration or "skewed"

This is a hydraulic powered lift gate, and it is normal for these to be slow. If excessively slow it needs to be diagnosed by someone familiar with the normal operation of the lift platform. Ask a mechanic with hydraulic control experience to look at it. DO NOT ATTEMPT TO REPAIR YOURSELF!

It all depends on the connections. Ask Delphi for details on how to install it in your model/make/year vehicle.

Bad thermostat. If it happens in city driving it might be the sensor that controls the radiator fan. Either way a simple fix.

Either the teeth are one on key or maybe the tumbler has turned.
