Answer 1

Reset the light and drive it. Give the computer a chance to detect problems.

A bad O2 sensor can cause an engine to run too lean which would be worst when it's cold.

Answer 2

Nissan Camshaft Position Sensor

Answer 3

Hi, I have a similiar problem right now too! I have a 2004 Nissan Sentra with 76,000 kms on it. In July, I started the car early in the morning when it was very cool outside (maybe just a couple of degree's) It was cold enough that there was frost on the windshield. I did not let the car warm up and just went...bam...the Service Engine Light came on. I had a local service shop test to see what the error message was and it returned a code that it was the Right Cam Shaft Sensor. I had them clear it and I called the Nissan Dealership and they said not to worry about it unless it fires that message again. \r\n

In September when the weather started getting colder, I noticed that when my car is cold it starts to sputter. I step on the gas and it feels like the car starts pulling back. However as soon as its warm...the problem goes away. One morning it was cold, I got in and went and the Service Engine light came on. I took it to the dealership and they replaced the Right Sensor. A month later the same error message came on and again they replaced the Sensor. I have had it back for 3 days and the error message came on...each time when its cold outside and the engine is not warm while starting to drive.



In total they have replaced the Sensor 3 times and cleaned the "grounding bolts" on the car thinking this may be apart of the problem.



Today I recieved a call from the Nissan Dealership and they said the problem is with the Timing Chain. They said the Timing Chain has stretched. I asked how this would have happened and I was informed that it is often due to not having regular oil changes. I informed them that every oil change reciept is in my glove box and that Oil Changes have always been done regularly on the vehicle. The service guy said that, oil changes are often the problem however it may have just stretched. (How??? still didnt get an answer for that)



Question? Does this sound accurate? They first thought it was the whole computer and now the Timing Chain. They want me to pay 2200 dollars to fix it. They have been consulting with thier Tech Support people who advised them, it was not the shop Foreman.
