Well... I arrived at a red light and my car just shut off!

The lights were still on...and the radio too.

I just started the car up again by turning the ignition.

what could this be?

do I need a new battery?

thanks

 

Oh my god my car is having the same problem i just put a new battery in it and its still doing it. out of the blue it stalls when im coming to a stop or even sometimes i let it idle can someone please offer insight as to what this may be?

 

I had that and it was due to a bad crankshaft position sensor.

what is the ball park price for the crankshaft position sensor and where is it located on the car if thats not a dumb question?

 

could be engine coolant temp sensor also.

 

Could be a million things. Check for codes.

 

he is right and i can assure u its not the batery if all ur acessories are still working

ckp( crank pos sensor) is a posible cause but not 100% so dont get that done merley because someone else did and it fixed the problem because You may have a different problem then sumone with the same symptom

 

I know it could be a million causes but is there a common problem that 4th gen max's have i've heard the Crank Position Sensor a few times?

 

it very well could be the ckp seeing as alot of times this problem happens it is but dont just throw parts at it hoping to fix it cuz sumone else fixed it this way.. youll usualy be disapointed in the end

 

Werd. I was stumped as well, and refused to try random things that others posted. I went to the Factory service Manual and went 1-by-1 by the checklist included. (Took a week for me to diagnose and the ckp was a "low possibility item" according to the manual.)

Here's where you need to start:

Those are the basic things to check out. Check each one and get back to us.

thanks guys


Im going to check my codes this week

Im going to change all my sensors at once (oxygen and ks as well)

 

I had the same exact problem when I first got my Max and theres no need to waste time checking codes.

I can bet 99.9% that its the battery terminal. Check where the screws are around it and try to jiggle it a little for loosness. Also look for corrosion.

If its loose and the screws seem loose, you found your problem. You can either buy a new terminal or get bigger screws and drill bigger holes into the terminal to get a snug fit whitch will get the car to stop shutting off.

 

don't forget about the mass air flow sensor. that could cause this as well. if the sensor is not bad, the wires that lead into the plug could be coming loose (especially if you have an aftermarket intake). just my $.02

 

dont forget that you could have run out of gas. even if it says "F" the fuel guage could be bad.
