Cam Position sensor


D1Style

Recommended Posts

Have you guys had issues with this sensor before? Anyone know what causes them to fail??

I've had 2 stuff out on me in 2 years on my V7 Sti. Just happened again today. Same symptoms as the last 2 times. Car sounds like its running on 3 cylinders, back fires, no power.

The last second hand sensor i bought lasted me a year before it crapped out today.

Will find another second hand one for cheap to use in the meantime while i order a brand new one from overseas. Seems to be about $120 cheaper then buying here!!

What was up with yours?

Had the cel that would show up constantly, even after putting in a new sensor (and replacing the crank sensor with a spare I had). The mechanic mentioned most likely due to wear and age of the socket expanding from vibrations over time.

Yeah the 02s are notorious for the cam sensor issue. I put a 1mm washer between the cam and the socket and that seemed to solve the issues. Even after paying $200 for winger to check the timing belt.

Can you post a pic of what you did please bro??

forgive the incorrect bolt (photo purposes on an old sensor :))

Using the 1mm washer fixed the random cels. While thinking about it according to the workshop manual "The correct gap is between 0.15mm to 0.98mm (0.0059 to 0.0386 in.)" So I have just put it out of range by a whole 1mm.

Not to be a buzzkill but I'm skeptical as to how moving it away from the cam pully would help a faulty sensor. Normally the failure mode is an open or intermittent soldered joint inside the molded plastic, or crap on the sensor face. I wonder if the process of refitting the sensor is adding a few more weeks to its life. (I used to have someone crank the engine while I wiggled the sensor just to get a dead sensor to work long enough to start)

Different models seem to display different symptoms. Earlier Subys simply won't start with a bad cam sensor and it seems the newage+ are more sensitive and bring up CEL's while driving which may disable the variable valve timing system. My brothers V7 STI drove poorly with intermittent CELS until he replaced an iffy cam sensor.

I will attack a sensor in the weekend and take some pics

      Afternoon team,
      im new to the group first time posting. Im hoping some body can help me get my launch control all dialled in on my link g4x. Ive had the computer and car all tuned from chris at prestige awesome knowlegable guy super happy with the results but now im wanting to get my launch/anti lag all dialled in. Ive been reading multiple different forums etc all with different conflicking information which has made me nervious with what do i listen to this or that if you get what i mean. Now ive started to make myself familiar with my PClink software etc the past few weeks and im eager to learn how to do minor setups or tweaks etc so im not relieing on my tuner so much and obviously saving myself abit hurt in the back pocket. 
      Now back to the question at hand.... Im wondering if theres and one who could please share there knowledge and wisdom with setting all my values, timing, fuel etc when i have launch control armed and engaged, or even a launch tune file they can possibly send me to load onto my tune. Ive figured out the setup of my digital inputs turning launch control on etc and its obvisously on its pre set factory settings. It engages but doesnt sound the greatest or as angry as it should i feel. Hence reaching out to you good buggers. 
       
      Cheers in advance for any info and help yous maybe able to give me.
       
      Cheers Shaun
