If you see this code, your thermostat is probably starting to fail! Also, make sure you verify the readings of your Intake Air Temperature sensor are right, not too hot or too cold in relation to both air temperature and under-hood air temperature. A proper mechanic should do this. I learned my lesson there, next one I removed before disconnecting the electrical I found a trick while re-installing it, too, and that was to lay a moving quilt across the engine, the I layed across the engine from the passenger side, and wallah! The retainer should point towards you. Don't blow it down with air. If the thermostat sticks the the engine will overheat causing damage. If the Coolant Temperature readings reach the right range, then the fault is most likely in your Thermostat.
The next step is to see if the engine temperature sensor is working correctly. Using a pair of channel lock pliers pinch the end of the hose clamps on both ends of the upper radiator hose. The resistance across the sensor terminals should change with the temperature according to the chart that you can find in the. So I started the Engine and checked these two sensors. Not 100% certain on this one On the 3.
If your are for a different car, select that vehicle series before searching for the diagnostic codes because not all used by one manufacture are used by the other makes. I usually put some Di-electric grease on the connections too. In other words, there is a problem with the engine operating temperature not being reached within a certain amount of time. Car manufacturers require coolant for several reasons. Just some comparison shots: The Mopar seemed to be of better quality than the aftermarket for the most part. My write up may be different from the kits currently out there, so alwasy double check the manufacturers installation instructions when installing anything.
You will also notice the engine temperature needle dropping when driving at higher speeds along with a check engine light in the console. Twist the upper radiator hose back down and slide the end over the thermostat housing. The air flow coming into the engine is accumulated and used to determine if the vehicle has been driven within the conditions that would allow the engine coolant to heat up normally to the thermostat regulating temperature. Disconnect the harness by pressing the clip and slowly wiggling it off. Drive a car for 10 minutes and check the engine temperature again, it should be close to 180-220°F or 82-105°C. Once the engine reaches its operating temperature, the thermostat opens.
No that is not normal at all. However, there are other ways to fix this code as well. We allow links, pictures, video, or audio file to help diagnose your problem. You can wipe it off, just use a lint free rag and be careful. All posts without this information may be subject to being removed.
However, if not repaired and the vehicle is used over a long period of time, there is a small chance that water contamination of the oil could cause deterioration and engine damage. The good rule of thumb here is to get the Air Temperature at 100° F below the Coolant Temperature readings after warmup. This is due to a leak in the seal or the thermostat open stuck. If the readings from the Coolant Temp fall out of required range, then the Thermostat is the culprit. What repairs can fix the P0128 code? I took it to Auto Zone the told me the code that came up was P0128. Use a flat tip screwdriver to loosen the two 2 hose clamps holding the intake tube to the throttle body and air box.
P0128 code courtesy of the Torque App. If your are for a different car, select that vehicle series before searching for the diagnostic codes because not all used by one manufacture are used by the other makes. In most cases, distilled water is enough to cool the motor even in the hottest summer months. This isnt a place to post your youtube channel 5 Mark Solved. I've had it come up at least 3 times since I've done the coolant temp sensor replacement. If you have any doubt as to repairs on your vehicle, please contact your technician.
This is a zero tolerance policy. Take a look at your throttle body. If this is the case, the connectors will typically deteriorate and cause a poor connection. It might have something to do with age or high mileage, but one of the primary reasons is accumulated rust and debris in the thermostat. If you have a scan tool with live data, check the engine temperature when the engine is cold, it should be close to outside temperature.
