P1885 code questions
When I run the live data it's showing all 4 cams in spec? not sure what im not seeing here.
2015 e350
also how do I clear the intake blocked ice code? ive tried and it keeps coming back
thank you very much




I would swap the Intake Camshaft Position Sensor between banks 1 and 2. Rescan, if the message switches banks, you know the sensor is toasted.
When you are disconnecting the position sensors -> CHECK for oil in the connectors.

sorry forgot I did replace the sensor already

It looks very much like a soft-crash... could be "oil-in-harness" or perhaps old undersized relays (30g found under 8.5VDC)
You can tell the ECU is crazy calling a CURRENT fault on the camshaft position you are showing to be perfect.
- Were the old CPS failed before replacement ?
- What the current engine mileage ?
- Any rattling involved (cam wheel) ?
Right now you could:
- reboot the chassis (batts out 10mn)
- clear faults
- rescan
- drive 25mph roads
- rescan
- compare results
I would keep out of highspeed roadways for safety against limp-modes or until you get this all sorted out.

not sure how I can read more modules?
I got the code before and replaced it but it didnt change, I didnt notice any excessive oil on the connection.
how do I reboot the chassis?
battery out for ten min? correct ? ok ill have him do that.
I really dont understand the ice faults... ive tried to clear them several times... pretty sure there is no ice there..
No rattling , but there is a leak in the AOS or whatever its called near the rear of the engine.
I think 109kish
it does take longer to start from cranking, maybe 1 full second or so.
other than that its been a great running car, no real issues before this. bought it I think in 2019?




49/11/33...
your chassis runs with 49 computers out of which 11 of them report 33 faults. Super bad ones can also be missing silent units.
We want to see the complete set or at least all 11 faulty units.
Reboot chassis by disconnecting BOTH batteries for 10mn (without shorting the leads!).

- reboot the chassis (batts out 10mn)
- clear faults
- rescan
- drive 25mph roads

Once properly charged, or best NEW, delete and rescan. Those should NOT be back.
Too many communication errors- wonder if there is poor contact on the CAN connectors, or some central module, Gateway?
With those voltage levels, the computers cannot work reliably

I did buy a new battery will charge and replace and see what happens after that
note, I just checked I replaced it 4/22 so its not very old at all... it still could be bad I supposed... I did disconnect both batteries

I am surprised the STORED codes will not clear...
There a chance your ECU received "oil-in-harness" - Have a look at ECU connectors while your battery is disconnected.

You can also try deleting while disconnected, reconnect, rescan

The question is what produced all that chaos...
-- Jump-started flat battery (user error!)
-- Genuine ECU issue (CPS... Oil-In-Harness...)
-- Combination of jump starting with pre-existing issues

Some of these cars eat batteries because of unstable CAN-B modules... thenk a CTEK float charger is a great workaround + bi-monthly reboots to sanitize sleepless CGW.
We want to understand what helped this chassis become unreliable.

I left everything disconnected overnight and will retry in the morning.
which sensor is for the ice fault?

Now, there is definitely a communication problem. Did you disconnect the ECU and check the connector are extra clean, i.e. no oil?
