Code P0128 on 2006 Honda Civic EX?

The P0128 code on a 2006 Honda Civic EX indicates a problem with the engine coolant temperature sensor. This sensor is responsible for measuring the temperature of the engine coolant and sending this information to the engine control unit (ECU). The ECU uses this information to adjust the engine's fuel injection and ignition timing.

A P0128 code can be caused by a number of problems, including:

* A faulty engine coolant temperature sensor

* A problem with the wiring to the engine coolant temperature sensor

* A problem with the ECU

To diagnose the cause of the P0128 code, a mechanic will need to:

1. Check the engine coolant temperature sensor for proper operation.

2. Check the wiring to the engine coolant temperature sensor for damage.

3. Check the ECU for proper operation.

Once the cause of the P0128 code has been identified, the mechanic can then repair the problem and clear the code.

Here are some additional tips for dealing with a P0128 code:

* If you see a P0128 code on your car's diagnostic display, it is important to have it diagnosed and repaired as soon as possible. Driving with a faulty engine coolant temperature sensor can cause damage to your engine.

* If you are experiencing any other problems with your car, such as engine overheating, poor fuel economy, or decreased power, it is possible that the P0128 code is the cause. Having the code diagnosed and repaired can help to resolve these other problems as well.
