I started my car after getting out of work. It started normally with no issues. but the catch was it died immediately after. RPM went up and down once or twice and it cut off. Tried starting again and same thing happens. Took out my OBD II scanner to see what was up since i didnt see any error messages on my idrive. I got a P1017 error from the reading.

P1017
- Valvetronic eccentric shaft sensor circuit is open or shorted
- Valvetronic eccentric shaft sensor poor electrical connection
- Missing reluctor on valvetronic eccentric shaft sensor
- Faulty valvetronic eccentric shaft sensor

Greatttttt...so i called AAA to tow it to the local independent shop that i know and before truck got to me i tried starting the car for the hell of it again and it fired up but with check engine light. Regardless i wasn't gonna risk driving 25 miles on the highway during rush hour with a car that can potentially cut out at any minute. I tow it to the shop and checked for the codes again it cleared on its own and car fired with zero issues.

Now the question is do i still get it checked out? or do i just assume it was one time hiccup?? Wish i knew about this when i took my car in for service last saturday

You probably have the very common and very easy to fix dirty VANOS solenoids. Look in the DIY section, its a 2/3 hours job accessible for the most modest wrenching skills.

vanos would give you ses light but would still run. most likely eccentric shaft sensor. might be oil in connector





here is a diy and photos from above Thank you MrQuickR1

if this is the culprit parts and labor are 1500-1600 on average

It was the malfunctioning sensor...i just got my car back this afternoon. Thank god i didn't have to pay anywhere CLOSE to that labor rate...regardless it was an expensive fix

[hugus311]

indy should be around 900 considering part alone is 450.
glad it all worked out

So I gather valve cover off to get to the sensor and replace?

Glad that you got it sorted out!!

No problems since i got the car back from the shop...(i do pray for a smooth start before i push the button now )

Was the sensor flooded with oil, or just silently defective ? Any other symptoms before it failed ?

I'm not sure if it was flooded or not with oil....The night before it failed, my car was jerking ever so slightly every time i let off the gas pedal...like it was caught in between shifts..thats about the only abnormal thing i could think of before it failed.

My car has been like this for a year & half I'm wondering why it isn't making the engine come on .they tech did tell me the car can eventually not start I thought he was lying but I see he wasn't .so once you replaced the sensor the car was good no more problems

I have had no problems since i got the sensor replaced. It also got rid of occasional rough idling where the revs were jumping up and down between 500 and 700 rpms when idle

I'm sure you can get it for cheaper online. i just needed it fixed right away which is why i paid premium for parts
