I have the car listed above CVT idsi. Blinking d light.P1888 dtc appeared. Reverse is okay but drive is failing. I already changed CVT speed sensor. Checked wiring and harness seems fine and with continuity. What could be the problem? Please help me. Thank you in advance.

Let's check the fluid condition to see if the transmission is burnt which is common in these cars. Lets try to do a fluid service. here is a guide to help you step by step with instructions in the diagrams below to show you how on your car:

It seems like my CVT fluid is fine, the color is okay and no burnt smell. One more thing I noticed is that everytime I try to test drive the vehicle in cold condition the drive mode works but after approximately 1 0minutes when the vehicle turns to optimal temperature the problem occurs again.

Hi Jay Ar Sulo,

It sounds like transmission issues and should proceed to diagnosis.
Here are a chart below to proceed. For the that code.
Also if you have a tester to check transmission temperature that would help as well.
Let us know what happens and please upload pictures or videos of the problem.
Cheers, Nick

Hello sir. I noticed on the diagram you send to me is for Honda Civic, my car is Honda Jazz. Do you think they have just the same diagram?
