P1258 is an OBD-II Code that refers to Engine Coolant Overtemperature Protection Mode Active. To know more about this error code, keep reading.\u00a0<\/em><\/p>\n

What is a P1258 error code?<\/span>\u00a0<\/span><\/h2>\n

The powertrain control module (PCM) uses the engine coolant temperature (ECT) sensor to monitor the engine for an over-temperature condition. This condition occurs when the coolant temperature is above 128 C (262 F). When an over-temperature condition is present, DTC P1258 will set. <\/span>\u00a0<\/span><\/p>\n

The PCM will disable two groups of 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. ECM (Engine Control Module) gets a P1258 code when the PCM (Powertrain Control Module) tells it that the engine is too hot. <\/span>\u00a0<\/span><\/p>\n

When this happens, the ECM will turn off the primary ignition system to keep more damage from happening. When the engine coolant gets too hot, the P1258 code is set because the protection mode is on.\u00a0<\/span>\u00a0<\/span><\/p>\n

Engine overheating <\/span>\u00a0<\/span><\/h2>\n

It’s never a good thing when an engine gets too hot. If you catch the problem quickly, you can avoid having to deal with a major engine repair. If you know what’s in the next guide, you’ll be able to make the right choice when one of the following symptoms shows up.<\/span>\u00a0<\/span><\/p>\n

What causes engine overheating?<\/span>\u00a0<\/span><\/h3>\n

There are a lot of things that can cause an engine to get too hot. One of the most common reasons is that the cooling system doesn’t have enough coolant. If this level is low, the heat inside the engine will stay, and as the temperature goes up, steam will be made. <\/span>\u00a0<\/span><\/p>\n

Most of the time, low coolant is caused by a leak in the system or the engine. A mechanical problem, like a thermostat that won’t open, will stop coolant from getting into the radiator. This will also cause the car to overheat. A broken head gasket or a cooling fan that won’t turn on are two other mechanical problems that can happen.<\/span>\u00a0<\/span><\/p>\n

\u00a0If you run an engine while it is too hot, the pistons will expand and get stuck in the cylinder bore, and the engine block and cylinder heads will crack. If you think the engine is overheating, don’t try to check the coolant level or open the cooling system because it is under pressure and hot coolant can burn you if you aren’t careful. Before checking for a problem, you should always let the engine cool down.<\/span>\u00a0<\/span><\/p>\n
