P1306 error code

[Pappu1]

this code is on the v7-v10 OBD2 cars (and the related legacy and foresters that fall in that category)

it is specific to AVCS equipped cars only

its not a common code but its pretty much a PIA and involves a lot of tracking around the loom/oil control solenoid

basically start on the pins of the OCV and trace continuity from there to ecu

also, open oil banjo bolt and see if the little filter has dislodged and stuck (best to remove while u there)

wiring:

avcs solenoid - plug e37/38

goes to b21 plug by battery

then to ecu -

b84 plug

pin e17/16 e6/12 (the left and right pair)

also manually power the solenoid and see if it moves as a dead solenoid will give same issue

while logging the issue:

you will notice the avcs advanced will be mostly static and only moved few degrees from accelerating from idle to near redline back to idle (normally moved from low to max and back when doing that)

also the learning will be stuck to IAM=8

and lastly the OCV current will be static (being a break in the circuit)

--

ok another thing that can happen to the AVCS OCV is that one side filter can fall off from the oil banjo and get stuck on the solenoid and fix it to a particular angle

this can be seen in the logging as a stuck avcs angle

also if one side is stuck at say 25edeg and the other is normal say 0deg at idle, the car will sound like lumpy cams

this does not really give of a code as the ecu sees the solenoid sink current etc

mods: sticky this please

Minaj had the same problem with this code. turned out to be a broken wire.

His one was the cam sensor wire code but yea strange how only 1 wire in loom broke

Wirng ones are pia to sort especially if it\'s shorting randomly

Tends to happen when about 7 different garages monkey with your engine bay and then you go full boost rape it down the motorway
