U1001 Nissan - Fuga 2007

Question

i own a nissan fuga 2007 model and suddenly the engine stoped and wont start when i checked if found codes u1000, u1001 and p0507. How do i fix these errors?

Answer 1

We dont have Nissan Fuga here in the US, but you can try these

P0507 is throttle body related. I would try to clean it and do an idle air relearn.

Possible causes:

- Dirty throttle body
- Electric throttle control actuator misadjusted or damaged
- Faulty Electric throttle control actuator
- Intake air leak
- Poor electrical connection to the Intake Air Control (IAC) valve

 

U1000 and U1001 are codes for a bad ground. 

Many of the Nissan cars that has the U1000 the first thing to do is lossen all the ground connecters clean them with sand paper on the connector and body and retighen the bolts back 

There will be a few by the engine bay and will look like this lossen all the ground connecters clean them with sand paper on the connector and body and retighen the bolts back 

There will also be some under the steering wheel or glove box, I dont have picture of the model or I would post the locations.

You can also add a grounding kit to help the factory grounds since the factory grounds are thin and can lose connecting since you can rust and or have corrosion.
