2010 Carrera S 6M Cab 150k miles
TLDR: Dealer tells me the code is 2402 and Durametric returns 0024 with a description that matches the dealer.
I am getting screwey values when I look up actual values.
I try to clear codes and they don't seem to clear.
Has anyone else seen this?
I got CEL after about 1000 miles after replacing the catalytic converters myself. I pulled the codes with my Durametric and got:
0024 - DMTL Diagnosis module for tank leakage; pump drive rUpper limit exceeded
0010 - Intake camshaft driver
I took it to Porsche because I wrongly figured this was related to my cats. They pulled the codes and said the car was throwing 2402 and that the 0010 was in the system but had been there for a long time and was not relevant.
Now I had cleared that 0010 about a half dozen times so I thought it was fresh. It did not register at the time, but that means my reset did not work.
They said that it would cost $1,100 to replace the DM-TL and filter. It was very likely the right thing to do because they tried to actuate it and it would not spin.
As I have dropped about $14k on my Porsche habit in the last 30 months and my wife has had about enough of this, I paid the diagnostic fee and replace the parts myself (saving about $700).
Now my Durametric is still pulling the same codes plus a new one:
0014 which it says is No signal/communication
That code, like the 0024, is not in my copy of the Porsche 997 essential companion.
So when went to look at live values relevant to the DM-TL the Durametric was putting in some weird results. Percents or bars when the units should have been seconds.
Background: DM-TL is a complicated pump/sensor that determines that there are no leaks in the gas fume recycling system. It pulls low amps if there is a leak, so a high value means there is a problem with the pump or maybe a short.
Okay guys, I have been getting the CEL with this code for a while... reset, drive a few times, no light... then returns on way home from Autocross... So I order a post-cat O2 sensor and when I go to put it on, I notice that the Cat for bank 1 (Driver side) is on the other side because the exhaust crosses behind the engine... I assumed that since it monitored the exhaust from bank one that it just plugged in on the other side of the engine bay. I thought I was right because I drove it a few times with no light but on my way to Autocross last weekend, it came on again. Before I start undoing stuff, do I have it backwards or does the car look at it as Bank1 if the sensor is plugged in on the Bank 1 side. As anyone who has done this knows, it is a pain in the butt to get these in and out of a 996 GT3 so prior to subjecting myself to the discomfort, I figured I would solicit advice. Thanks!!!
Recently I had been noticing issues with my cooling system the coolant temp guage would go past the 0 on 180 and I wouldn’t hear fans or anything. (Already tested fans and resistors and relays). The temperature Will continue to creep up if I sit still, with no signs of fans, AC OFF.
I replaced the coolant temp sensor. Problem fixed!! Then same issue again it seems after a week of driving.
Now i currently have ordered another temp sensor just Incase I maybe did something to cause the other new one too fail, I’ll be changing it again today.
However I was doing the climate control hack to check my actual temperatures today while doing a short troubleshooting drive. And I noticed my oil temperature said 0, which is physically impossible 🙄
Is it possible the oil temp guage is throwing off the coolant sensor? Is it even possible for the oil temp sensor too go bad but not the oil level sensor? (They are a 2 in 1 sensor)
THANK YOU IN ADVANCE
2000 Boxster Tiptronic with 113k mi. I recently removed the transmission to deal with another issue, but while doing so some of the brittle SAI hoses cracked and/or became disassembled. I have replaced the cracked lines (i.e. not all of the lines) and reconnected according to the following picture, with the exception that I have a Tiptronic and there is a hose that runs to a changeover valve on the transmission:
I get the typical SAI codes, P0410 (80) and P1411 (208), about every 150mi driven. Otherwise the car drives great...SAI pump is running and holding air as usual.
Presumably, I have something connected incorrectly, possibly with respect to connection to the transmission changeover valve. The one thing I notice different than before removing the transmission is that the car seems to be running cooler than before. I suspect this could be caused by the changeover valve for the transmission as I think it controls the flow of coolant to the ATF cooler (not sure about this and hoping for clarification). The other thing that I don't really suspect, is that the new hoses used do not have the small bulbed end to help with that snap-fit into the intake sleeves.
I have not found a good image showing the SAI hose routing for a 986 Tiptronic, so if anyone knows of one I would be very grateful. I have the Bentley manual which also does not show a Tiptronic-specific diagram for SAI routing.
Any other ideas or does this sound like simply incorrect hose connections?
Many thanks for your input!
