Code: P1386 Camshaft Overadvanced (B2)

[fpr000]

this is starting to sh*t me off, ive taking the valve cover off and checked OCV's and valves etc and all looks fine, the chain is tensioned and no marks at all, and guides are fine???????????? wtf

[ratter]

recheck the cam timing, we have seen this code quite a few times and normally the cams are out 1 tooth, normally caused by a broken guide, the plastic breaks off the top of the moving guide and falls into the crank gear and causes the chain to jump.

[fpr000]

Nope!! Checked everything the cam gears are in line and everything, if I up the ignition by 1 degree it stops it??? Again wtf

[JVK]

Are they factory cams or have they been replaced?

[Mr_4.0]

Can you datalog Your cams on an xcal for us? Log duty cycle etc. Might give a clue.

[ratter]

log camshaft error

[Mr_4.0]

What's acceptable Mick?

[ratter]

It varies all the time as per any closed loop operating system, but have seen approx 15-16 degrees error when it has jumped a tooth.

It appears 15 degrees does not set the code and light but approx 16 does, well that's we saw a few weeks ago with one.

check the ohm resistance on your cmp sensors should be between 280-380ohm could just be a sensor fault had that on a lpg ute last week and I check valve timing ocv and vct actuators ended up being a exhaust cmp sensor mine was bank1 (intake cam) p1381 and p1340 were my codes.

You have rough idle and surging on cruise and full throttle?

Cheers neil

Thread revival!

 

I too am having this problem, I'm getting p1381 and P1386. ( bank 1 & bank 2)

I have removed the cam cover and inspected the timing chain, all of the guides are fine, and the chain looks fine.

 

I used a screwdriver and got one more click out of the tensioner but that hasn't seemed to help.

has anyone else had these symptoms?

 

I'm thinking I might remove the cam cover garnish and check the resistance on the sensor next, any other suggestions?
