There are 2 pedal position signals in the sensor. These can range from a faulty spark plug lead, shorted kill switch or flywheel key damage. Regardless of how you approach it, you should get this fixed right away. However, every once in a while it is possible that the thermostat will not fix this code. These can range from a faulty spark plug lead, shorted kill switch or flywheel key damage.
Spark plugs typically need to be replaced every season or 25 hours of use. Continue driving and see if the check engine light turns off. If this is the case, the connectors will typically deteriorate and cause a poor connection. All you need to do is take the old one off and screw on the new one. If the radiator hose heats up slowly, the thermostat is stuck open or opening prematurely and needs to be replaced. Overheating your engine will result in engine failure Code P0128 Common Diagnosis Mistakes Many just replace the thermostat without checking all possible causes.
If your coolant condition is poor, flush the coolant system and replace the coolant. This fault wont cause the stumblering problem. Spark plugs typically need to be replaced every season or 25 hours of use. If either fault is recorded again on the next engine startup, code P0128 is triggered. You should also check that the spark plug gap is set properly. The solution is here : Dodge Dart P0128 Possible Solution : Disconnected, dirty or fouled spark plugs are common causes for engines that won't start. Also it might be the temp sensor is bad? YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle.
This could also mean there might be a engine coolant temp sensor issue erratic temp feedback signal values. Pull over, retighten it, and take a look at the cap to see if it has any cracks in it. If the scan tool reading does not match the thermometer reading closely, then there is an issue with the sensor side of the car. A simple way to diagnose this is to feel the radiator hose and monitor how hot the temperature of the coolant is when it starts flowing through the radiator hose, however, you should be extremely careful when doing this as you could be burned. Done smoke text checked vent valve or charchole canister and all hoses and wires. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.
If the connector is okay, then generally the sensor is at fault. You have to be careful because it is hot enough that you could be burned. The hose should be barely warm until the thermostat opens. So, what this all means is that if the P1404 is a false code meaning that the valve pintle is not stuck open, then new 'Valve Closed Signal' can be re-learned by the computer using the old valve. Additionally, once the 160º F threshold is achieved, the recorded engine temperature must not fall below 160º F during operation.
P0128 code definition Coolant Thermostat Coolant Temperature Below Thermostat Regulating Temperature What the P0128 code means The P0128 code means that the engine coolant is not getting warm enough, fast enough. The fix goes like this: 1. If your spark plugs look good, problems with your ignition system can also preventing a spark. Thanks Kimberly K Anderson March 22, 2019 I have a 2004 dodge dakota with a po128 code and a small evap leak code. The determines if a signal is incorrect by calculating where it should be, inferred from the other signals. I had this happen with my '01 Grand Am. Posted on May 27, 2010 You are not the only one: www.
You can back check to ensure the correct part was installed. Then i was checking my email and there was my diagnose and fix in detail. Plug in scanner, go to data list and read coolant temperature sensor, start vehicle. So you should chech it on our car models. If the hose gets hot all of sudden like it should, then the next thing to check is the reading you are getting from the coolant temperature sensor.
The pedal position signal is converted to pedal travel degrees rotary angle by the. You need to compare this reading to one obtained by an. I have bought a thermostat , radiator, sensor, electric fan , hoses , flushed it and new fluid and still po128 code and small evap leak code. P0128 is not a very serious code. Now don't ask yourself; What should you do with P0128 code? Anyone had this issue and how was the issue resolved. If you know where the sensor is, you only have to unclip the old sensor and replace it with a new one.
If a concern is present with one of the circuits the other input is used. Then when I would turn the lights on the licens plate lights would turn off and the other running light would come on and the other would cut off. The predicted engine coolant temperature is compared to the Engine Coolant Temperature Sensor reading. Now don't ask yourself; What should you do with P0128 code? The ohm reading will change with the temperature. Refer to the following Top 150 Challenger Tips'n Tricks for more technical information.
The vehicle was warmed up about 5-10 minutes before highway driving. The 2 pedal position signals make sure the receives a correct input even if 1 signal has a concern. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. To do this accurately, you need a scan tool, but a reading is also possible to obtain if your car a has a temperature gauge. Watch what the water temp actually does. Now I have joined this group of people as I got mine fixed using this trick also.
