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
I have a 2007 C2S manual with about 132K on the odometer. A low oil pressure light has started to show up at idle after the car is warmed up. It seems as if the light is gradually coming on more frequently. The pressure gage on the dash reads around 0.5 bar when the light comes on. When the car is cold the starting pressure is around five bar and is about 3 bar at 3000rpm. As it warms up the pressure drops to about 2 bar at 3000rpm. I always run 0-40W Mobil 1 and change the oil every 5K miles. With the engine off and turning the key one click the pressure gage rises to about 0.1-0.2 bar.
Can anyone help me diagnose this issue? Would be a sensor or something mechanical?

Hello, I'm new on this forum and stumbled upon a new problem (or old) with my 2.5l 986 Boxster from 1997.
The problem occurs when the engine is started dead cold after sitting a few hours/overnight.
Engine starts immediately but the RPMs start to surge / hunt between 1100 and 700 RPM. This continues for about 10 seconds after which the idle smoothes out to the normal cold idle RPM.
The first pull away requires a tad more throttle then normal to prevent stalling. After this first pull, everything is almost normal and engine performance becomes better and better. When the engine is hot, the idle sits at 780 RPM with a minor fluctuation now and then (seems to be more than normal)
I've been to two shops (official Porsche dealer and local Porsche specialist). Porsche dealer couldn't find anything and the specialist found the camshaft sensor on the left bank to be unplugged - but now comes the strange thing - the cabling is nowhere to be found!!!!!!? Took the car home to check myself but didn't find anything.
No camshaft related codes to be found in the diagnosis and no CEL either.
Attached one pic showing the sensor and it's missing plug
Could someone help me out? - Is it possible for the engine not to throw a CEL when sensor is disconnected? - where is the sensor wire to be found?
Hi Porsche Gurus
I’m trying to troubleshoot a little issue I have that just my drivers door courtesy lights (and drivers sunvisor light but not sure if that’s different issue) don’t work, both the red and white ones and only the one door(rhd car)
now ive checked the common things like all the fuses and the wiring to see if they were damaged or corroded but they seem fine,
The one thing I would like to check but can not find any info on is where or what is the switch or sensor that tells the lights that the door is open to turn the lights on?
If I can find that then that will at least eliminate all manual fixes that I can think of unless any of you have come across this before, if it’s something simple and I look like a fool for not thinking of it then I’m happy to be a fool as long as the lights work:)
any help would be much appreciated
I installed a complete Used FVD Brombacher exhaust this weekend. Headers, Cats, Mufflers, 02 Sensors. When installing the FVD exhaust I noticed that the post catalytic O2 sensors were on opposite sides of the stock headers. (2001 C2 Manual) The leads were not long enough to go to the opposite side connectors. So I plugged them into the sockets closest to them. I was able to drive for about 30 miles until the CEL light came on. I noticed the idle was a little off, would fluctuate between the 760 - 860 range I think . Car drove fine. When I got back home I checked the codes.
P01030 O2 Sensor Curcuit Bank 1
P1130 Oxygen Sensing
P1126 Oxygen Sensing
P0300 Random Misifre Detected
P0306 Misfire Cyl 6
P0304 Mis Cyl 4
P0305 Mis Cyl 5
02 Sensor Output 0.0v Bank 1 Sensor 1
I hope you enjoyed my drawings.
Would this be due to the post cat O2 sensors be plugged into the opposite connectors? Plugs and tubes were replaced about 6K ago, all the coils looked fine. The 02 sensors came on the exhaust. Could this just be a bad O2 sensor? Would it be advisable to get the DME re tuned for the new exhaust?'
