Idling sensor and effect on AT

[Toalson]

Not sure what you call them, but there is a idle sensor which if faulty can have an effect on the AT. My car was recently diagnoise with that. And the mech told me, I was fortunately if not have to change another sensor for the AT.

 

However, after the change discovered that idling not ideal cos can rise above the normal previously. And today the gears suddenly jerk when moving off. Got a fright. The most pressing issue is mechanic is missing prolly due to illiness. Was suppose to have him check on the problem after the idle sensor was replaced cos he suspected the wires could be faulty as well. I hope the mech was not pulling a fast one as his business oso not too fantastic recently.

 

I am worried that car cant last the 10yrs..... All things change after last servicing with change in EO to 30wt and renewal of ATF.

 

Any comments on mech's assumption? As may have to go to other mech if current is still missing.

Huh??? What's an idling sensor? Located where? So you changed or did not change the sensor (whatever it is)

 

If you mean the MAF sensor (this controls the amount of fuel to supply based on the airfow),then perhaps. But it should not only affect idling..... loss of power, your CEL light will also come on if its dead.

 

Go get a 2nd opinion at another workshop.

 

If you ask me.... 1st thing check the ATF level lah.... if its too low, also will have jerks.

[Toalson]

Sorie but think its the MAF sensor. ATF level checked and found to be ok.

 

Fortunately manage to contact the mech but his health is not looking good, but he will check for me once he's fit. Thanks.

wad car. how many yrs.

engine stalled when moving off. mine's an auto car.

 

after engine restart, car is v sluggish.

 

one faithful day it totally can;t start, towed to workshop and discover sensor faulty n starter failed due to overcrank.

 

but i forget wad sensor already. jus 2 of the sensor that failed. it failed during its 3yrs 8mths. 120k mileage.

I think you mean the crank sensor. It can affect cranking and car stalling issues if defective.

It could be the IAC valve (Idle Air Control) that is giving problem or the contact to it that is tarnished and not having proper connection for electrical current to conduct.

Thanks, tat is similar to wat mech expalined to me over the phone as well.

[Kb27]

Yeah, it's probably IAC that gummed up.

Just curious, did you change out the stock air filter?

[Vtim]

hope the problem is solved

[Toalson]

Have alaways being using normal paper filter.

[Toalson]

Nope, as mech is not fit for work. He's a freelance and will honour any issue if the sensor was to be faulty, thus decide to stick to him. Guess it there wont be issue if I carry on drive with is idleing issue rite?

[Vtim]

mostly you'll have rough idling issue, sometime may (or may not) stall.

[Toalson]

That's what i think as well. Guess have to cross my fingers that it would ceased while driving. Now hoping that mech is fit as car also need to be prep for inspection.

[Vtim]

what you can do is, whenever you come to a complete stop, put on the handbrake or footbrake then at the sametime tap gently on the accelerator to hold on to the Rev to prevent stalling

[Toalson]

Ok, but so far the rev will just keep moving up and down but not to the extend to stall. Hope not.
