Thanks! Actually we went through that process before posting. The solenoid for the front trunk release is actuating and opening the latch. We closed latch manually with the hood open and as soon as we hit lock or unlock on the key fob the solenoid actuates and latch unlocks. Could it be the alarm control unit? Thanks.
Hey, have an 01 Boxster with a hood latch that releases when the car is unlocked with the key fob and when you use key in door. It also releases randomly when driving. It has been adjusted and the latch assembly appears to be fine. So what could cause the system to randomly send a signal to unlatch the hood? Anyone have this issue before? Thanks!!!
That's one problem I'm having. I can't trigger the variocam solenoid while running the cam angle deviation graph with Durametric software I can only do them as separate functions. I called Durametric and they said it was my laptop not using a dual core processor. So this afternoon I dragged out a new computer with dual core processor and guess what.... still didn't work! I can hear the idle change when I do activate bank 1 and bank 1 but I can't see what is happening. At this point I'm stuck because Durametric won't be available until Monday again. Do you think this could be a DME needing re-flash? Although that seems odd since it's a '99 with 109,000 miles on it. One would think if that was the problem it would have shown itself long before now. So I'm still stuck.
Okay so just to confirm: 1) My screen shows 25 degrees, so it's off, by a lot it seems. 2) Likely nothing is bent, ie, cams. The reluctor wheel that the cam sensor uses to sense timing appears to line up correctly, we are checking this with motor in car. Is that wheel what you are referring to as VarioCam flange? 3) My cam deviation value on bank 1 is 25 degrees and does not waiver so it is probably not the IMS 4) IMS is cause for strange cam timing issues, but my timing deviation value does not move SO, what else might have caused it to get out of time? Here's my concern, I pull the engine, find the timing off, reset timing... but don't correct what caused it so it will likely happen again.... right? Before I pull out this motor I want to be absolutely sure I've exhausted all other options. Thanks so much for your help!
Thanks for your stream of conscious thoughts! I am finally getting back to this one. My laptop died but it's back up and running. As to 3) I just decided to change it to make sure it was not the problem and as I suspected it didn't not change anything. As to 1) how or why does the chain skip? What would cause that if the engine has not been taken apart? As to 2) how would a cam bend if the engine hadn't been pulled apart? Have you seen this happen? As to 4) How can I tell if DME is the problem and needs to be reflashed? Short of taking it to the dealership is there a way to check it? I have the durametric software. Finally, is there a way to set timing without removing the engine? Thanks! y
Yet I don't have codes for cam position sensors or crank position sensors so I'm assuming they are good. Hmmmmmmmmmmm
Okay actuated both variocam solenoids. Car reacted to activation for both. Still showing 25 degrees. The intake cam has a notch at one end but not both ends like the exhaust cam does. This is a 5-chain car if that makes a difference. The only thing I can think of is that the intake cam is out of time due to a worn chain pad???? What is strange is that with the engine off the active screen reads 25 degrees as well and when you turn engine on it doesn't change. Almost as if it isn't reading it correctly at all. Where does it pull data from? y
Okay, a couple of adds. First, I can only see Camshaft 1 position deviation in my list of 'available actual values'. I checked again this morning, still 25 degrees and it never moves. Second, I don't see a way to trigger the VarioCam, when I clicked on drive link "adjust camshaft" the whole thing froze up. SO, we pulled cam end plugs. Exhaust cam is perfectly lined up. Intake cam doesn't have marks going all the way across it, but the cams are tied together so it doesn't make sense that one of the cams would be off and not both. Also, when I checked codes again this morning I did have misfires on 1,2, and 3. Any more input?
I can't view your screen shot.... the link takes me to a login page. But I will check solenoids in the morning. Thanks I really appreciate you help.
Hmmmmmmmmmm Here's a screen shot.... so do you think it somehow jumped time? Loose chain or something like that?
Okay current codes: P1340 and P1125 oxygen sensing adaptation. At idle the Camshaft position 1 deviation is 25/crk it never changes either at idle or 2000 rpms. It feels like a misfire at 2000 rpm but no misfire codes are popping up. This rough idle issue has been happening since end of April. I suspect if it was IMS failure it wouldn't have made it this far. Any other ideas?
Yes that is what my OBD reported. Using Durametric software. Another shop originally diagnosed the car as having a bad dual-mass clutch disc... after replacing spark plugs with no improvement in symptom. So the guy had the clutch done... which of course it didn't need. Rough idle started up all by itself. Chain wear.... hmmmm. How to assess that....
Hey! Anyone ever get a P1340 on their 996? The car has a rough idle but otherwise runs fine. I cleared all the codes and then did a test drive. Rough idle at lights. The light did not come back on but it had P1340 and P1125 in the system. Anyone with any thoughts? Thanks. y
Okay, if you have any thoughts: if we jam voltage on the motors to move the top half-way it will operate in the down position but will not go up at all. We removed switch and bench tested, it's good. Leaning towards control unit.
