Sign In Test for both power and ground at the fan. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Sign In yes im sure its a us vehicle. I found this solution at another forum on this issue. Other wise the re-learn process does not take place. There are two rubber hoses maybe 3 inches each that link formed plastic line to the solenoid. Sign In Those codes are listed for that vehicle in Motor3k If you look in the radiator fan description and operation section it does have the option of dual fans.
The solution is here : Dodge Grand+Caravan P0480 Possible Solution : Disconnected, dirty or fouled spark plugs are common causes for engines that won't start. But in many cases, it means at minimum that you'll be visiting the car dealer to locate the malfunction and get the light turned off. Now Follow Step 9 Now Follow Step 10 8 Check the connections at the relay. Both headlamps may also have small levels on each of them. These can range from a faulty spark plug lead, shorted kill switch or flywheel key damage. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.
These can range from a faulty spark plug lead, shorted kill switch or flywheel key damage. Battery voltage greater than 10 volts. They made the hose molded into a tight U shape and replacing this with a longer hose will fix the issue. Now I have joined this group of people as I got mine fixed using this trick also. If you run into the P0480 code and find that the fan will only run on the highest speed, start by checking for a blown cooling fan fuse 1 in the underhood fuse block. A code scanner is a very handy tool to have and I recommend everybody who is just slightly hands on type of a person to get one.
Sign In With a test light that reads both power and ground and test the 2 wires going into the motor while unplugged to see that one has power yellow and one has ground black. There have been some issues with the programming within the control computer that causes the fan to not work right which will cause this code. Sign In well thanks guys for all the info and help, im sure ill be back on here with more issues at a later time. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional. 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. Do you see any problem? Over time, when the instrument wears, a slightly different signal is sent to the computer and when it differs enough from the 'Valve Closed Signal', that the computer had learned, the trouble code P1404 is set and the 'Service Engine Soon' light comes on. You stated that you were getting power to the fans and I seriously doubt that to be true so check it again and check for ground also.
It won't look as pretty but it will save the headache of ordering the factory replacement and doing it over every few years. Disconnect electrical connectors, and replace the bulbs. P0420 Dodge Description The Engine Control Module monitors the switching frequency ratio of heated oxygen sensors 1 front O2 sensor and heated oxygen sensors 2 rear O2 sensor. Both relays have the same part number. Sign In Use the diagram to determine what's missing on the other one. Here is a description of the problem and possible causes. Should there any problem within the circuit that will cause the fan to fail, the engine will heat up, causing it to overheat.
This avoids people flashing their lights at you. This code is similar to P0481 and P0482 codes. Sign In well i got two fans, two codes. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. Sign In Yep, that's what I'm saying.
I have doubts about your testing because that code is for a fan control circuit. This can happen whether the vehicle is sitting still or driving at slow speed. Now don't ask yourself; What should you do with P0480 code? So you should chech it on our car models. I just checked 2 different data sources Alldata and Mitchell and found the same diagrams in both so something is different about this vehicle that I'm not aware of. Posted on Jul 29, 2010 actually there are 4 sensors. Tech notes As the code description implies the P0420 code means that the vehicle's control module has detected that the three-way catalytic converter is not working properly is not as efficient as the factory is expecting. How to Fix Repairs for this error code are pretty simple and straightforward, and of course can be derived from a thorough diagnosis.
The last thing you want is to replace are components that are working perfectly. If you know where the sensor is, you only have to unclip the old sensor and replace it with a new one. This is accomplished with a professional level scan tool. Being that the vehicle is a 2016 you need to take it to the dealer and have them reprogram the computer which should take care of this. Sign In Well, all 2004 with 2. Then they test the fan control relay using a relay tested, or switch the relay using a good relay to test.
