I originally checked the oil level, went ahead and drained the oil anyway and check the filter for any type of debris… All was good refilled the oil with a 5W 40, if my memory serves me, and I have replaced the oil sending unit, the crankshaft sensor, and now I’m trying to locate the camshaft sensor on Bank one and having difficulty with that…
Leading evidence: 'Check filter' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check filter' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

Check wiring to the sensor — heat damage is common

If it’s a .2 changing the cam sensors is an easier job, with the .1 you need to drop the engine, so if you have swapped out one sensor without dropping the engine then it’s defo a .1
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

My 2001 Porsche 911 996C2. Cabriolet is sending me a code called 0011… I’m having trouble finding the cam timing sensor on Bank one… Any help is appreciated
Porsche fault code P0011 indicates the bank 1 intake camshaft is over-advanced, meaning it is positioned further ahead than the ECM commanded, often due to oil pressure issues, faulty VVT solenoids, or timing chain stretch. Key, often low-cost, causes include dirty engine oil, thick oil, or a stuck solenoid (OCV).
I originally checked the oil level, went ahead and drained the oil anyway and check the filter for any type of debris… All was good refilled the oil with a 5W 40, if my memory serves me, and I have replaced the oil sending unit, the crankshaft sensor, and now I’m trying to locate the camshaft sensor on Bank one and having difficulty with that…

Camshaft Position Sensor – Bank 1 (996.2)
On the 996.2 (3.6L M96 engine):
There are two camshaft position sensors (one per bank)
Bank 1 = cylinders 1–3 (right-hand side of the car when sitting in it, UK = driver’s side)
Location (Bank 1 sensor)
Mounted on the rear of the cylinder head
Right-hand bank (Bank 1)
Positioned towards the gearbox end of the engine
It sits just above/behind the exhaust cam area, near the chain housing
How to actually find it
Access is the annoying part:
Remove the rear engine cover inside the cabin (behind the seats)
You may also need to:
Remove the airbox/intake ducting
Move wiring looms slightly out of the way
Look down the right-hand cylinder head (Bank 1) toward the back:
You’ll see a small sensor with a single bolt (usually 5mm Allen or Torx)
Has a 3-pin electrical connector
It’s not easily visible from underneath — top access is usually easier on a 996.
Common confusion points
People often mix up:
Camshaft sensor vs VarioCam solenoid (they’re close but different parts)
The cam sensor is:
Smaller
Electrical only (no oil line like the VarioCam actuator)
Since you’ve already replaced:
Oil sending unit
Crankshaft sensor
Oil & filter
What exact symptom are you chasing?
Because on these engines:
A failing cam sensor usually gives:
Hard starting
Misfires
Fault codes (P0340/P0341 etc.)
But if your issue was oil level / pressure related, the cam sensor may not be the root cause.
Before pulling it:
Scan for codes if you haven’t already
Check wiring to the sensor — heat damage is common
Some 996.1s have dual camshaft sensors. If you have post cat o2 sensors or e-gas then you get two sensors. If you've got a cable throttle you've most likely got one (the wiring diagram is a little unclear...)
This is a source reference. Confirm exact model applicability in the original material.
