I have 2000 cadillac deville and its overheating


P0741 - Torque converter clutch slip speed is exceeding limit; P1258 - High engine metal temperature. Sounds like you have transmission problems - torque converter problems can cause engine overloading, which in turn can cause the overheating. I would start with a complete transmission check before the engine is seriously damage the engine.

2004 chevy express van codes p0894


P0894 Transmission Slipping
P1258 Engine got Hot
P1516 Throttle Actuator Control (TAC)

Chevrolet Tahoe vehicles may experience a performance issue where they will not go over 15MPH. The vehicle may appear to be in "limp-in" mode, giving just enough power to get you to a shop. over-hood-250x300.gifThe codes indicate a problem with the throttle position sensor circuits and throttle actuator performance. Do NOT start replacing parts. Shops report a pattern failure in the electrical harness to these sensors. Chevrolet has issued a revised replacement harness to correct the problem. The original connector was prone to vibration and broken wires that disrupted the signal to the PCM and put the vehicle into reduced power mode.

I have a 1996 cadillac deville with codes PO741 and P1258 current. Tonight it shut down as I was driving, what could be the problem?


P0741....Torque Converter Clutch Circuit Performance or Stuck Off
P1258 Engine Coolant Overtemperature - Protection Mode Active
the first code is a generic code the latter code is a GM code and if this is correct the engine shut down because it was overheating for whatever reason or the sensor is faulty

P1258 CODE


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"
