    I have the same code I got it cleared through the scanner. Mine came on when I released E brake and put in gear. Sometimes I get a noise between park and reverse on an incline? I don't know should I be worried or call the mechanic. Husband in Korea for another 7 mos so he can't help.

U1120 is Lost Wheel Distance Message. Not sure what you could have done while doing an oil change but one (1) of three possible items are the issue. CAN C BUS CIRCUIT OPEN Or SHORTED or ANTI-LOCK BRAKE MODULE or PCM. One of the three has an issue.

U codes are undercarriage codes, It can be possible that this code is directly related to a mistake done while the oil was changed. Although a description of the code will help a little more.

Check engine light on


erase code again , then disconnect battery for a few minutes, reconnect, see if code comes back. hopefully this resets computer. you don\'t have a reset button on steering wheel do you ? replace your fuel filter, if you haven\'t lately. maybe that will help.

2006 dodge sprinter came from oil change and engine light is on and cruise control not working. checked oil and is at correct level


Stop by Auto Zone or another parts store that will read the fault codes for free and get the fault code. That will tell you where to look. Most likely it's the O2 Sensor being faulty. It is about the right time to change that.

My check engine light came on and the car started stalling. I checked the oil, and there was absolutely none. I put a container and a half; drove around for 10 minutes. The noises and stalling stopped, but...


Yikes! You say there was no oil, did the 1 and 1/2 quarts bring it up to the full mark? If it did, you still had about 2 and 1/2 quarts in the engine. This was certainly bad for the motor if it was making noises and stalling. If it sounds and runs well now, you may have dodged the bullet, however, the engine took a beating from being run low or dry. You may be able to reset the check engine light by just removing the negative battery cable for about 10 minutes, hook it back up, the light should reset. If it comes back on, have it checked (parts stores will check for free) to see what is going on that causes it to go on.

Check engine light after oil change


If it is the service engine light, go to Auto Zone and they will put a scanner on it for free and diagnose the code. I may have fixed the same problem with my daughter's 2004 Dodge Stratus 2.7L V-6 a few months ago. Is it the "Oil Pressure Light" or the service engine light? My daughter's car had a sporadic low oil pressure light. Checking the actual oil pressure is more work, so I guessed it was the Oil Pressure sending unit and it was. When I took it off it the electrical connection was soaked in oil due to some internal failure. I put a new oil pressure sending unit on and the oil pressure light has not come back on.

If you remove the wire connector and there is no oil on anything, try sparying it with electrical parts cleaner and putting it back together. If the oil light is still on you will need to replace the sending unit.

It is an easy job, but it must be done from the underside of the engine in a tight space. Make sure the enginer is cool because the sending unit is close to the exhaust. There is an aluminum heat shield with three (3) bolts that needs to be removed and is most of the work. You will need to plug the hole with a clean rag or wait for the next oil change to do the job and replace it after you drain the oil.

If the easy steps above do not solve the problem then you may have bigger trouble like a bad oil pump, or worse yet, a really worn out engine that needs a rebuild.

Just last week, I has a SEL scanned at Auto Zone and it turned out to be the Engine Coolant Temperatuere Sensor. I removed the electrical connection and sprayed it with electric parts cleaner and put it back together. No light since then. Good Luck!
