If your Jeep Wrangler is displaying a p0128 code, it means that the engine is not reaching the correct operating temperature. This can be caused by a variety of issues, but the most common cause is a coolant leak. Once you have located the leak and repaired it, you will need to reset the code. The following guide will show you how to reset the p0128 code on your Jeep Wrangler.
Most Jeeps come with P0128, which is usually caused by an open coolant thermostat. When this happens, hot coolant should begin to flow, and the radiator hose should be quickly warmed up. This problem code can also be found on the intake air temperature sensor, coolant temperature sensor, and coolant fan. If the P0128 code is not met, the engine coolant is not getting warm sufficiently fast. A faulty thermostat, low coolant levels, or other issues can all be the source of the code. A coolant temperature sensor is used in a cooling system to measure the coolant/antifreeze mix temperature. It is estimated that the cost of replacing a Jeep Wrangler Thermostat will range between $68 and $86.
Will P0128 Code Clear Itself?
The P0128 permanent code will remain in the system until it has completed so many cycles that it has not detected the low coolant temperature.
If the engine is not starting, a faulty coolant temperature sensor could be to blame. Failure to regulate the engine or an overheated thermostat are two other possible causes of the problem if the engine does not overheat. You’ll need to bring your car in for service in either case. If this code indicates that the engine is not overheating, it is possible that the thermostat needs to be replaced. The engine overheating is most likely caused by the coolant pump or thermostat.
Can You Drive With A P0128 Code?
Is it safe to drive with P0128? Despite the code’s illumination, your vehicle will still drive even after you plug it in. As a result, the vehicle will not be hampered or stopped abruptly. If the temperature gauge does not reach the desired level, it is the only thing that will cause trouble.
P0128 indicates that your coolant thermostat is operating below the temperature set by your fix sensor. A P0128 code can be triggered by a faulty wiring or an engine that is not responding quickly enough. There is no coolant, and the temperature remains constant even though there is no coolant. The temperature can quickly rise in an overheated vehicle if there is no radiator fan. The first step in troubleshooting P0128 is to examine the engine’s thermostat. Temperatures should range between 160 and 200F in general. If there is no sudden heat up on the radiator hose’s exterior, it may be possible to argue in this case.
Before scanning your vehicle, you should double-check whether P0128 is already present or not. It is best to first check the coolant system in order to resolve any issues. The coolant in question contains a lot of rust, so the rust must be removed as soon as possible. If you notice a change in voltage, keep an eye on the voltage reading. If the thermostat has become stuck open, there is a problem. Examine the coolant system in order to ensure it is operational. If you overheat the engine, it will degrade over time. How long can you drive a car with a P0128? It is not recommended to drive for more than 1000 miles.
What Does The Code P0128 Mean On A Jeep Wrangler?
P0128 can be caused by a stuck coolant thermostat, which is one of the most common causes. Feel the radiator hose to determine how hot the coolant is when it begins flowing through it, and then monitor the temperature of the coolant as it enters the radiator hose.
If you have a Jeep P0128 code, you must first diagnose the problem. Engine temperatures can be calculated and analyzed using the live data functionality of the FIXD sensor and app. RepairPal-certified shops have a minimum 12-month warranty on all repairs lasting 12,000 miles or more. It is possible that some repairs will be required to fix or diagnose the underlying issue of Jeep P0128. A repair’s cost will be determined by the cost of the necessary parts and labor. If you want to make your own diagnosis and repair, follow these steps. The most common cause of P0128 is an open coolant thermostat in an engine. It is a simple way to diagnose this by gently touching the radiator hose and measuring how hot it feels when the coolant starts flowing through it. A loose fitting connector or a low and dirty coolant are common causes.
Reset Check Engine Light Jeep Wrangler
If your Jeep Wrangler’s check engine light is on, you can try resetting it by disconnecting the battery for 30 seconds. If the light comes back on after reconnecting the battery, then you’ll need to take your Wrangler to a mechanic to have it diagnosed and repaired.
A Check Engine Light (CEL) is a warning mechanism that kicks in when a system error is detected. When the CEL comes up, it is most likely unrelated to the engine. Furthermore, it can be indicative of a problem with the transmission, emissions control mechanism, or ignition system. It is most common for experts to use an OBDII scanner during this procedure. If the smell in the engine bay is strong, it is a strong indication that the gas is needed. In some cases, you can simply keep driving until the light goes out on its own. Even so, I would still recommend clearing the codes.
