Is it OK to drive with P0128?

Can I drive my vehicle with a P0128 trouble code and illuminated CEL? You may drive your vehicle with a P0128 trouble code. You will not notice any issue except for maybe the temperature gauge never reaching normal levels, and possibly the Check Engine light being illuminated.

The most common cause for P0128 is the engine coolant thermostat is stuck open. When the thermostat does open, the hot coolant should start to flow and quickly warm up the radiator hose. If the radiator hose heats up slowly, the thermostat is stuck open or opening prematurely and needs to be replaced.

Can low coolant cause P0128?

Low engine coolant can alter the engine running temperature enough to signal trouble code P0128. Your intake air temperature sensor, coolant temperature sensor and coolant fan could also signal this trouble code, so these should be inspected after you look over your thermostat and coolant level.

  6. Engine Overheats.
  7. Poor Idling.

What can cause a P0118 code?

The onboard diagnostic (OBD) code P0118 is an Engine Coolant Temperature Circuit – High Input malfunction. When the engine has been running for more than a few minutes and the ECT is reading a less than freezing temperature, the PCM thinks there is a circuit fault and sets the P0118 code.

What is the code P0113?

The P0113 code is one of many codes that are created by your car’s Powertrain Control Module (PCM). If your PCM is returning a P0113 error code, it means that your Intake Air Temperature (IAT) sensor is reading at too high of a voltage. This sensor works as a basic resistor.

Will low coolant throw a code?

The code could be triggered by anything from a low coolant level to a faulty thermostat that you may need to replace, so you must do your homework. Air tends to get trapped in some systems, so make sure you know how to properly refill the cooling system before even beginning the job of replacing the thermostat.

What does the code p0128 mean on a Chevy Silverado?

Please try again later. A P0128 is a code is an indication of a faulty thermostat or ECT (engine coolant temp sensor).

What does it mean when your car thermostat is p0128?

When the thermostat doesn’t bring the engine all of the way up to the proper operating temp, it means that the water going through the heater core isn’t as hot. This leads to less/no heat.
