Problem micra K11E (1.4 l)

[CMF_monben]

hi,

I lost one of the screws fixation of the Mass Air Flow Sensor. Where can I find an equivalent screw?

hi,

I made a diagnosis of lambda sensors with nissan Datascan II. Here is the link:

and MAF :

i think 22 is high for a long term fueltrim, and 8 to 9v on both lambda,s ??

 

[CMF_monben]

Theoretically, the data points of the two lambda sensors. Is the statement of the second sensor is right?

Sensor readings of air temperature is it normal too?

For now, I have tested the relay of the ECSS, it has not shown weakness and the car is not fallen down.

 

[CMF_monben]

it is in the LTFT B1 standards, right?
it should be at 2000 rev / min from -25% to 25%.
this value is constant whatever the rev / min.

 

[CMF_monben]

MAF readings are weird.
Measures on the link in the previous post about the maf up to 22 V is obtained (normal maximun is 4v).

 

[CMF_frank2]

yeh, its not making a lot of sense eh monben, the maf reading might be in gram,s ? and the fueltrim +22 % ?, but the o2 sensor readings/values look corrupted to me

 

[CMF_monben]

That's incredible. That makes two weeks I use the car to try to make her fall down. Today, I let my wife. it takes to go for a full tank and it does not restarts. I rage because I go back tonight from work and I could not test it SINCE will reboot.
It seems that it fails when it is very short drive as is my wife. fortunately it does not have the children.

 

[CMF_frank2]

sounds like its flooding if it wont restart after a short run monben, i have a volt meter wired to the lambda for continuous feedback and diagnosis http://www.ebay.co.uk/itm/390685872370?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

hi,

thanks for your response, the link has problem "The page you requested was not found."

 

[CMF_frank2]

its just an ebay seller mate ebuy4nz

 

[CMF_monben]

you suspected what lambda sensor: the first or second.

 

[CMF_frank2]

monben WROTE:

"you suspected what lambda sensor: the first or second.

your datascan 11 did,nt make any sense to me mate, try a different software maybe ?

 

[CMF_monben]

Here are the exact path of the car this morning. 1 course 800 meters 8:40: home to school with one minute stop at school. Then second course 800 meters 9.00: school to home with 20 minutes of downtime at home. Finally trisieme golf 2 km 9.20: home to petrol station and breakdown.
I think my course for two weeks are not the same.
I have a road 50 kilometers to go to work and between noon and two o'clock, I go back four kilometers. that's why it does not crash.

They say the lambda sensor:
"Lambda regulation does not occur until the engine has reached its operating temperature."

 

[CMF_frank2]

the lambda,s are electrically heated monben, and are should be at operating temperature within 1 minute

The problem came well the relay. I swapped the fan relay with that of ECM and started ca. Thank you so much for everything.
I will look after the problem of low idle hot and probably the lambda sensors are for something.
