Problem micra K11E (1.4 l)

[CMF_monben]

Hello,
K11 is a 1.4 petrol 08/09/2000 (motor CGA3DE ) . When cold, it starts without a problem . Then after several stop randomly and once heated , it turns empty without restarting (alternator and battery checked OK) . It was not until it cools to that that she can start times one hour or overnight.
I changed fuel filter , spark plugs , air filter , cleaned the flowmeter , bought a ODBII ( no error back of the computer ) Error player.
I finally take it to a specialist who kept injection 11 days without being able to put it down. They changed even when the pressure sensor in the computer that you were able to default. They never had a computer error. So I ended up back and he told me in case it fails verify that it was not the transponder key that was not in default and not recognized by the computer 4 weeks after she ends up falling down with the same symptoms. The I retéléphone him and he told me that he had in the meantime even a micra that failed with the same symptoms and micra finally told them that it could come from the chain distrbution was relaxed. the cost of repairing this fault is 1200 euros.
I thought he ****s my mouth to come help me or not it was really serious. D Based on the information I have is that rather K12 problems that K11 chains .
That 's why now I ask your opinion on this.
Thank you in advance for your answers.

Coolant temp sensor maybe ? (not the chains)

 

[CMF_monben]

hello,

Thanks for your response. if the temperature sensor coolant was down, the ECU would report in default?

 

[CMF_frank2]

if the sensor is faulty, the ecu will run constant coldstart enrichment (like leaving the choke on)
does it idle bad when hot monben ?

 

[CMF_monben]

When the engine is warm, idle is low (550 rev / min) and not very stable.

 

[CMF_frank2]

ebay code readers are,nt 100% accurate really, maybe try a nissan dealer check ?
or you can test the signal from the lambda sensor (it should be bouncing around .45v @ idle and cruise)
if its constantly .9v when hot, then the coolant sensor is probably faulty

 

[CMF_monben]

If I understand correctly, I must first also test the lambda sensor (voltage around 0.45 V at low speed and high speed), and then test again hot (if the voltage is 0.9 V, it is the temperature sensor is faulty).
I take the voltage across the lambda sensor and not across the temperature sensor.
This is how I should do if I understand correctly.

 

[CMF_frank2]

the black wire on your 4 wire type mate, it should read about .45v at idle or steady cruise (signal wire and earth somewhere), and .9v at acceleration in low gears, and 0v on throttle lift, but if its constant .9v then the ecu is coldstart enriching

 

[CMF_monben]

honestly, this is the first serious help for 2 months and I thank you very much.
I could not do that weekend. I'll give you some news.

 

[CMF_monben]

hi,

I disconnected the connector and took the voltage on each terminal connector (ie lambda sensor disconnected): the first was the mass, the second battery power, the third a fixed voltage to 0.7 v which does not move, and fourth fixed voltage of 0275 V. The voltages are not varied at all depending on the speed.
voila, then in the dark it looks hot as the resistance of the water temperature sensor is infinite.
here are the first statements tonight.

 

[CMF_frank2]

if you disconnect the lambda, the ecu wont get the signals tho monben.
have you tried tapping into the wire ? (measure the voltage while still connected)

 

[CMF_monben]

thank for your reponse.
I'll try to take signal like that.

 

[CMF_monben]

Another problem appears. rarely. it happened to me three times. Unlit engine and the ignition on, flashing lights continuously few seconds. I think it has nothing have.

 

[CMF_frank2]

sounds like the faultcode light is flagging a fault now mate, have you tried the code reader again ?

 

[CMF_monben]

That's right, the engine was running with disconnected sensors.

 

[CMF_monben]

hello,

I measured. A terminal is fixed at 0.30 V. the other n not stop oscillating idle between 0.45 and 1.0 v.

 

[CMF_monben]

hello,

Is this normal (lambda sensor disconnected), rolling I do not feel any change in engine behavior.

 

[CMF_frank2]

idle should oscillate between about .2v and .6v at idle (warm engine)
and .9v only at full throttle in 1st and 2nd gears monben

 

[CMF_monben]

hello,

ar cruise, it always oscillates at 0.4 v and 1.0 v and idle it gives the same thing

 

[CMF_frank2]

1v is too high mate, have you checked the 2 wire coolant sensor ?
https://micra.org.uk/cmf/message/63444

 

[CMF_monben]

hello,

there are 3 wire at coolant sensor?

 

[CMF_frank2]

monben WROTE:

"

hello,

I take the voltage?

ohms monben, (resistance)

 

[CMF_monben]

18OO homs cold rather lukewarm

 

[CMF_frank2]

it should be 2500 ohms cold, and 300 ohms hot eh

 

[CMF_monben]

another phenomenon: when I put the lights or put something on the battery take the regime falls and then rises above

 

[CMF_monben]

I can not start the car the children sleep

 

[CMF_monben]

I am now a 2100 oms

 

[CMF_monben]

now 2200 ohms

 

[CMF_frank2]

if thats the 2 wire sensor ? then it sounds ok then eh.
lambda sensor problem maybe ? you could swap the 2 lambda,s (another lambda near the driveshafts)

 

[CMF_monben]

this morning : coolant sensor hot 300 ohms.

 

[CMF_frank2]

the MAF and 2nd lambda are pretty notorious for faults on the coilpack k11,s monben, i would check those first

 

[CMF_monben]

Hello,

I cleaned MAF yesterday with acetone. How to test MAFand guilty also test 2nd lambda sensor.
Thank you again for your response.

 

[CMF_frank2]

the ebay bosch type MAF is about 30 euro,s mate, but they have a bad reputation tho, and just swap your 2 lambda,s and measure it again

 

[CMF_monben]

in used equipment, it's worth?

 

[CMF_frank2]

monben WROTE:

"in used equipment, it's worth?

N16 are apparently the same MAF mate (QG15/18 engine)

 

[CMF_monben]

100 euros for each new lambda, it's hot.

 

[CMF_frank2]

check your 2 lambda,s first, fit the 2nd lambda in place of the 1st lambda

 

[CMF_monben]

I would do it tonight when I get back from work.

 

[CMF_monben]

this is the same sensor with the same connection?

 

[CMF_frank2]

monben WROTE:

"this is the same sensor with the same connection?

i think so
you could measure the MAF output from the diagnostic plug and android eh

 

[CMF_monben]

I must mount the car on blocks to disassemble the second lambda sensor. I will as soon as I have time.

 

[CMF_monben]

i can test MAF with this reader ?
http://www.ecutool.com/LAUNCH-CReco...r-OBDIIEOBD-Remote-Diagnostic-Tools_1731.html
I prefer working with netbook.

 

[CMF_frank2]

i guess so mate

 

[CMF_monben]

and this not expensive

[CMF_monben]

hello,

there are two temperature sensors one above the other? that I tested has two terminals and is below. And just above there is one with a terminal such as that and that has an electrical connection.
http://www.yiparts.com/Part/fr/NFEVFC
Should therefore normally also that the test, right? or it has no effect on engine operation.

 

[CMF_frank2]

the 1 wire one goes to the gauge monben

 

[CMF_monben]

hello,

I found this discussion and this is exactly the symptoms I have. What do you think of this track?

[CMF_monben]

hello,

I have removed the main relay and tried to start to simulate a failure. it does exactly what it makes when it is down: the starter turns the lights on and no default instrument cluster appears.

 

[CMF_frank2]

Try swapping the relays then eh

 

[CMF_monben]

I have two possibility I use the car and what I expect crashes, and immediately I 'swapped relays to confirm this. Or I replace now and I expect there to be down.
