If you’re a Dodge Caravan owner, then you may have come across the P0128 code. This code indicates that there is a problem with the thermostat or cooling system in your vehicle. In this blog post, we’ll take a look at what the P0128 Dodge Caravan code means and how you can fix it.
What is the P0128 Dodge Caravan Code?
The P0128 Dodge Caravan code is a diagnostic trouble code (DTC) that indicates the engine coolant temperature sensor (ECT) is not reading within normal operating range. The ECT sensor measures the temperature of the coolant and relays this information to the engine control unit (ECU). The ECU uses this information to adjust the air/fuel mixture and ignition timing to keep the engine running at its optimal temperature. If the ECT sensor is not working properly, it can cause the engine to run too hot or too cold, which can lead to poor fuel economy and drivability problems.
What Causes Code P0128 Dodge Caravan?
There are many possible causes for the P0128 code on a Dodge Caravan. The most common cause is a coolant temperature sensor that is not working properly. Other possible causes include a thermostat that is stuck open, a radiator that is not cooling properly, or a water pump that is not working correctly. If the coolant temperature sensor is the problem, it will need to be replaced. If the thermostat is the problem, it will need to be replaced or repaired. If the radiator is the problem, it will need to be flushed and refilled with new coolant. If the water pump is the problem, it will need to be replaced.
