I got 17 and 19 when my crank sensor was dying. I think they took it out of code lists before they took it out of the PCMs.

Thanks for the tip.

So the crank sensor was at fault ?

How hard was it to change ?

What was involved, pulley removal, etc. ?

Thanks,
Dutch

You need a balancer puller with 70 to 90 mm long M6x1 bolts (3). The sensor is behind the pulley. Before you remove the sensor, VERY CAREFULLY measure the exact position that the sensor is in relation to the crank shaft. The new sensor, even if it comes with a new bracket, will require adjustment to sit in the right spot.

Keep in mind, I'm not garaunteeing the crank sensor is your problem. But it sounds very likely to me.

Thats what I have been suspecting as well, either that or the ICM.

You don't happen to remember what a rough price was on the Crank sensor do you ?

Anyone know the price of a new coil pack just in case ?

Thanks again for the help,
Dutch

Your coils can't be the problem.

Price the ICM and the crank sensor through www.rockauto.com

You'll be hard pressed to beat their prices. Lean towards ac delco parts if they have them. Consider a new harmonic balancer now too. You'll have to remove it to change the sensor, and if it'* original, it'* past due for replacement and will likely fail within the year.

Sorry I meant to say ICM.

How do the Harmonic Balancers wear out ?
I thought by the pictures I've seen its just teeth that pass through the "Fins" on the crank sensor, but nothing actually makes contact or wears.
Is that correct ?

Will or anyone have a pic of a new one vs. worn ?

The reason I'm asking is cause I'm tight for cash right now. I have to replace a bunch of parts on the wifes car as well (figures they both break down at the same time).
My price for the Balancer from the Dealer is $240, List is $340. I'm going to check price at a local AC Delco dealer that I use sometimes.

Thanks again,
Dutch

The HB would be ~100 from gmpartsdirect. You're correct, the crank sensor and HB don't touch. It'* the rubber in the HB that cracks with old age and allows the outer hub several degrees of rotational freedom from the center and causes the loud clanging. It shouldn't affect the crank sensor.

$100 thats a little better.

Is that the price for just the balancer or is that including the pulley as well ?
I was told that the pulley and balancer come together as one, is this right ?

Thanks,
Dutch

The balancer and pulley are one in the same. It'* a pulley with internal weighting to help keep engine vibration down.
