Infiniti Repair Questions? Ask a Mechanic for Answers ASAP
so the vehicle starts without the maff but not with it plugged in? and what all did you replace before the starting issue? also what brand maf was it you used?
okay well the idle after replacing those parts needs to be relearned. either a shop with a decent scan tool or the dealer can do this.
that some times can work but not always. and idle relearn yes needs to be at operating temp. have you done the crank sensor un plugged method?
it very well could if there is too much pulsation it will actually lower the pressure causing it to stall out. why did you have to cut it?
when primed yes it will hold and should be fine. but the pulsations from the injectors is what causes the issues.
that's fine I would try the crank sensor method first. the fuel line may not be causing an issue.
i apologize for not responding work got a bit crazy towards the end of the day i was un able to respond. give me a few and i will look up those codes i never remember them all
all you replaced was th shaft sensr correct?
and the other sensors mentioned correct?
ok im sorry i de notice the throttle body replacement did you recalibrate the throttle body after replacement?
i apologize for the errors in typing i am having issues with my keyboard currently... it is wireless and the batteries are tired...
"i did not notice the throttle body replacement" is how it should of read.
gas normally around 6 months to go bad and var. they can be sensitive sometimes the slight wrong move distrups them oter times they will fall 2 stories and be fine.
what scanner do
ok well when you look at the data if you can watch the graph for the tps sensor aand b with the engine off key on when you slowly press the gas pedal to the floor both graphs should be a slow but steady transition from 0 to 5v or vice versa one is from 5v to 0 and one is 0 to 5v eiher way it should be smooth any noticeable hiccup then the tps should be replaced.
okay well you need to be able to read the sensor voltage on a scanner to determine the sensor data. percentage is not accurate enough. I have seen bad throttle bodys that were ne but not many. I would also check with the dealer to make sure that there are no updates for your ecm that are needed. I am not at work today so I can not look up the updates... I work at infiniti
