I have a 2002 chevy tahoe 4X4 with a 5.3L that has set a P1258 code engine over temp, it has also set a P0117 ect low input code, and a P1637 L terminal circuit, P1638 F terminal circuit codes.


If these codes are being only set during start I would expect a failure of the battery. If the voltage goes much below 9 VDC the computers (EMS) can become erratic and codes and limp home modes are a common result of defective and discharged batteries!



Careful having the battery tested. Any arcing etc at the battery can be the kiss of death for the engine computer. Better to remove terminal to check. Or test the crank voltage with multi-meter.

What is a code p1258 on chevy equinox


DTC P1258 - Engine Coolant Over-Temperature Protection



The powertrain control module (PCM) has the ability to disable 4 injectors during an engine over-temperature (overheating) conditoin. Engine is considered over-temperature whenever the engine coolant temperature reaches 268 F. This protection mode allows the PCM to alternate between groups of cylinders, thereby reducing coolant temperature. This is accomplished by disabling the fuel injectors. This DTC is set to show that an overheating condition was or is observed by the PCM and that the protection mode has been engaged.



You will need to inspect the cooling system to see what is causing your overheating issue. If the engine is not actually overheating, this code may be set due to a faulty engine coolant temperature (ECT) sensor.



Hope this helps, also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Low oil light came on 2005 equinox checked oil it was low there is a ticking sound. I put 2 quarts in started back up, light is still on also still ticking.


The lifters have to be primed with oil. This may take a while. Let the engine run, after a while the oil pressue light will go out, and the clicking will stop. If you have lost oil pressure the engine will shut off as a safe guard so it is alright to let the engine run while clicking as long as you have oil in the case.

2003 chev silverado truck 5.3 the code im getting is p1258 that means engine over heated and the truck did that so can any one help me


You need to figure out why it overheated. Check the coolant level in the radiator/overflow tank. Thermostat may have stuck closed, the water pump may have failed. If the coolant level is low then add coolant and check it often. If the coolant is up to the right level then I would probably change the water pump and thermostat.

Since the engine has to get pretty hot to set this code, You may have comprimised the head gaskets. Look at the dipstick for any signs of water ( milky oil) and take the cap off where you add oil and look/feel for moisture. If you do see any signs of coolant then you will need to remove the heads. I am not that familiar with the engine, but Chevy uses plastic gaskets for the intake on some engines and they have been known to fail.
