Thanks for all the answers, but I forgot to provide all the info. These are not just services that are coming soon. It makes a ticking sound and is slightly slower and faster when traveling at speeds of about 40 miles per hour or more. Thirst after oil change I have oil, I have been told that it looks like oil did not pass in January, it has 176,000 miles. I have a printout of error code P1138. Any other suggestions?

I found this while searching for your code. Copy and paste the following.

It has the code 1138 because the light is on. The code identifies the whirlpool control valve. My mechanic has information about dealer codes. He told me that the vortex control valve is activated when the cooling level for each cylinder is too low and the temperature is ideal for proper use. He told me to make sure the fridge was working. It started my engine fire again and it didn't start. Nissan made sure it knew what a whirlpool control valve was, what it did, and how it was used. I pointed several times to the right of the valve and it was powered by a cooling system. It's an easy-to-use, replaceable valve.

Its code is 1138 because John's light is on. The code identifies the Vortex control valve. My mechanic has information about dealer codes. He told me that the vertex control valve closes when the cooling level for each cylinder is too low and the temperature is right for proper use. He told me that the refrigerator was fine. My machine turned on again and it didn't turn on. Nissan made sure it knew exactly what the Vortex control valve was, what it did, and how it was used. I pointed several times to the right of the valve and it was powered by a cooling system. It is a convertible and easy to use valve.

I also have a Sentra 04 and the indicator light comes on, lasts for about a week and then goes out for spawn about a week later. My car code is 1138. I took it to the Nissan dealership for service. I was told that the vertex control valve was faulty and had to be replaced with an intake manifold to replace it, as it was connected multiple times. The good news is that it includes an emission warranty or a power train warranty, which is longer than the normal 3 year / 36K warranty. The Vortex control valve is part of the emission control, but since this intake is installed multiple times, I'm not sure what warranty it covers. If you call Nissan's US headquarters, they will tell you if the warranty is valid after 66,000 miles, and I'm sure they can tell you what the warranty is, if any. For example, always insured because repairs are not cheap.

This code is not available for 2004 Nissan vehicles. This code is P1130 for vertex control valve.

All we do at our dealership is check your ECM and verify the part number and see if it is listed. In that case, we will re-program your ECM and delete all your DTCs and drag.
