2006 Prius, 220,000mi. .. just started showing trouble codes P0011 and P0016 No other symptoms... Any suggestions appreciated.. thx
Google search reveals possible timing problems, might be due to worn timing chain. Not surprising for a high mileage car such as yours. I would have it checked out by someone who is a good Prius mechanic. Google "Prius P0011" without the quotes for more info. Sorry I can't be of better assistance on this. http://share.qclt.com/%E4%B8%B0%E7%94%B0%E6%99%AE%E7%91%9E%E6%96%AF%E5%8E%9F%E5%8E%82%E8%8B%B1%E6%96%87%E6%89%8B%E5%86%8Cpdf%E6%A0%BC%E5%BC%8F/Repair%20Manual/04pruisr/05/2054m/cip0011.pdf P0016 Error Code | PriusChat
From the 2010 DTC tables, not sure if same for your Gen 2: P0011 Camshaft Position "A" - Timing Over-Advanced or System Performance (Bank 1) - Valve timing - Camshaft timing oil control valve assembly - Oil control valve filter - Camshaft timing gear assembly - ECM P0016 Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A) - Valve timing - Camshaft timing oil control valve assembly - Oil control valve filter - Camshaft timing gear assembly (for intake camshaft) - ECM
Purely because it is the simplest and cheapest item check I would remove the camshaft oil control valve filter and clean it. This will cost nothing, but a little time. John (Britprius)
Were you able to find a resolution for the p0016 code? i have the same error code and have changed all the sensors and no solution.
After a major engine rebuilt a few years ago, I also started to get P0011 once in a while without any noticeable performance degradation. This usually occurs during a multi-hour long drive in a hot day. Replaced the oil control valve filter once when the code first showed up. I normally just clear the code or sometimes it would just clear by itself. Do not know if this is something that I need to be concerned.
How many miles on the engine? Was the timing chain replaced during the rebuild? P0011 means the camshaft timing is advanced more than 5 degrees from where it is supposed to be, so maybe the camshaft timing oil control valve has an intermittent problem, or the intake camshaft was slightly out of position vs where it should be, or maybe the timing chain stretched, or the VVT sprocket has a problem? I guess that if you haven't noticed a powertrain performance problem, then you can live with this indefinitely - if the engine was going to blow up based upon valve interference it has had a few years to do so already.
The engine has 270 k. It was rebuilt about 100 k ago. Timing chain was replaced as part of the rebuilt.
Is there a video on how to change the "CAMSHAFT TIMING CONTROL VALVE SENSOR".. I have searched youtube and can't find one for a 2007 PRius
It depends what you mean by the "CAMSHAFT TIMING CONTROL VALVE SENSOR" It seems it could be "Camshaft Timing Oil Control Valve. Was this phrase on a workshop invoice? The Variable Valve Timing (VVT) system includes the ECM, the Oil Control Valve (OCV) and the VVT controller. The ECM sends a target "duty-cycle" control signal to the OCV. This control signal, applied to the OCV, regulates the oil pressure supplied to the VVT controller. Camshaft timing control is performed based on engine operating conditions such as intake air volume, throttle position, and engine coolant temperature. The ECM controls the OCV based on the signals from several sensors. The VVT controller regulates the intake camshaft angle using oil pressure through the OCV. As a result, the relative position between the camshaft and the crankshaft is optimized, the engine torque and fuel economy improve, and exhaust emissions decrease. The ECM detects the actual valve timing using signals from the camshaft position sensor and the crankshaft position sensor. The ECM performs feedback control and verifies target valve timing. If it is the OCV, look up posts by EdtheFox as he replaced one. Some of the time, the OCV just needs the filter replaced.
Yes, that's the Camshaft Timing Oil Control Valve. Check the associated filter too. Look up Ed's post (VVT Oil Filter? Poor MPG'S?). Apart from needing a good quality tool to remove it, I didn't get the impression it was overly difficult. [EDIT} Post #1 in this thread: Replacing a 2008 Prius VALVE ASSEMBLY, CAMSHAFT TIMING OIL CONTROL Part Number: 15330-21011 might also be useful to you.
Thanks for help... this is the hex bolt for the VVT oil Filter 1 inch below "CAMSHAFT TIMING CONTROL VALVE SENSOR"
