Is it safe to drive with the P0128 code? The code will illuminate the check engine light, but you can still drive your car. It will not cause any hindrance or sudden shutting down of the vehicle. The only problem you’ll notice is the temperature gauge not reaching the optimal levels.

What causes a P0128 code?

What Are Some Causes of a P0128 Code? Error code P0128 indicates that your engine coolant temperature is below the thermostat regulating temperature. This means that your Engine Control Module (ECM) or Powertrain Control Module (PCM) has recognized that your engine is running cooler than it’s supposed to.

Can low coolant cause P0128 code?

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.

What are the symptoms of a stuck thermostat?

Thermostat failure symptoms that you should know

• High temperature readings. The main symptoms of a failing thermostat are related to engine overheating.
• Erratic changes in temperature.
• Leaking coolant.
• Increased fuel consumption.
• Unusual noises.

Will a stuck thermostat throw a code?

A stuck open thermostat can cause the engine to take too long to warm up, not reach proper operating temperature at all, possibly run rich, and MAYBE set that fault code. The engine electronics are programmed to see the engine operating in a specific temperature range.

How do I know if my thermostat is stuck open?

Remove the radiator cap and idle the engine. If the coolant flows right away, your thermostat is stuck open. If it is not flowing, wait until your engine warms up. The coolant should warm to the right temperature and begin to flow after 10 to 20 minutes.
