P0015 Camshaft Position "B" Timing Over-Retarded (Bank 1)

[hiflyer767]

Had same or similar issue about 100k miles ago after an extended OCI.

There are two oil pipes that feed oil to the oil control valve, one on each side of valve cover. At the top of those pipes, there is a bolt that holds it to the OCV. Take that bolt out, it is hollow. On the end of the bolt will be a plastic cased cone shaped filter with a metal screen. It should come out with the bolt, if not use a pick to get it out. Clean it up and reinstall screen, bolt to torque.

Also, pull the cam position sensors on the valve cover and wipe them off, may be some sludge on them.

Check PCV valve or just replace it, its cheap.

Ever since then, I change my oil every 5K.

THANKS FOR THIS INFO! It just did it to me again this past week, driving back home. I'm going to replace the OCV and the filter, as well. The oil is 500 miles away from being changed, but still clean!!!
So it's gotta be the OCV...and maybe the filter.

THANKS AGAIN!

I'm not a mechanic, but I did stay at Holiday Inn Express last night...

What causes the P0015 code?
The variable camshaft timing (VCT) oil control valve (OCV) is stuck in the open position.

The camshaft phaser is stuck in the retarded position due to damage or clogged oil passages.

Oil flow problems to the VCT piston and phaser from incorrect oil viscosity.

The OCV has an open circuit or the ECM has an open circuit.

The harness plugs are notorious for wires coming loose out of the back of the plugs when trying to pull them. Has happened to me both times I’ve changed spark plugs which had me pulling plugs, all on the driver’s side. The wires to the plugs can be repaired but you need the right crimps and crimping tools. Open circuits on these will have you unnecessarily changing expensive parts. Check every single wire at the back of the plugs.

I just had this exact same thing happen to me at only 52k. Took it to the dealer and they asked me when my last oil change was and what kind of oil I use. I usually go about 7500 miles between oil changes and the last one was about 2500 miles ago. I told them I use Pennzoil. They told me that may be the cause that some oils sludge up more than others and the Toyota oil has additives that prevents that. They did change my oil and clean my sensors and it is running smoother than it has in a long time. Could it really be the brand of oil I use?

They are full of it. I have 315K miles on a 2014 SR5 and I use Quaker State Synthetic 0w20 with change intervals of 10K miles.
