Resetting the P0128 Code: Step-by-Step Guide
If your car is displaying a P0128 code, don’t worry – you don’t have to take it to the mechanic right away. With our comprehensive guide, you can quickly and easily reset the P0128 code on your own. Our step-by-step instructions and detailed explanations will help you get your car running smoothly again in no time.
| Step | Instructions |
|---|---|
| 1 | Check your car’s coolant temperature sensor. |
| 2 | Check the coolant level and top up if necessary. |
| 3 | Check the wiring and connections of the coolant temperature sensor. |
| 4 | Check the coolant temperature sensor for signs of wear or damage. |
| 5 | Replace the coolant temperature sensor if necessary. |
| 6 | Reset the ECU (Engine Control Unit) to clear the P0128 code. |
Checking the Coolant Temperature Sensor
The first step in diagnosing and resetting a P0128 code is to check the coolant temperature sensor. This is an important component that helps the computer regulate engine temperature. To check it, you’ll need to disconnect the sensor and use an ohmmeter to measure its resistance. If the resistance is within the manufacturer’s specifications, you’ll need to move on to the next step.
Inspecting the Radiator
If the coolant temperature sensor is working correctly, the next step is to inspect the radiator. Make sure the radiator is filled with coolant and check for any signs of leakage. If the radiator is in good condition, you can move on to the next step.
Inspecting the Thermostat
The thermostat is the next component to inspect when resetting a P0128 code. This device helps regulate the engine temperature by controlling the flow of coolant. If the thermostat is stuck closed, it can cause engine overheating and trigger a P0128 code. To inspect it, you’ll need to remove the thermostat and inspect it for any signs of damage. If it’s in good condition, replace it and move on to the next step.
Checking the Relay and Fuse
The last step in resetting a P0128 code is to check the relay and fuse. The relay helps control the flow of electricity to the fan, while the fuse helps protect the system from excessive current. If either of these components is bad, it can cause the fan to malfunction and trigger a P0128 code. To inspect them, use a multimeter to check for any signs of corrosion or damage. If everything looks good, replace the relay and fuse and your problem should be fixed.
By following the steps outlined in this guide, you can quickly and easily reset your P0128 code and get back on the road. With our clear instructions and detailed explanations, you’ll have no trouble diagnosing and resetting this code. With this knowledge, you’ll know exactly how to reset p0128 code and can save yourself time and money.
Key Takeaways on How to Reset P0128 Code
