Which Codes Will This Page Cover? I felt comfortable enough to keep driving the car near the same speed, so long as I didn't let the RPMs surpass 3k. It indicates that there is an issue with rocker arm oil pressure switch. Join Date: Jul 2006. VTEC is workng fine now and I'll be driving it from Dallas to Lubbock tomorrow so I will have plenty of time to test it out.
My Pilot is about 1, 400 miles short of 60k... The Rocker arm oil pressure switch verifies the correct oil pressure in the Variable Valve Timing (VVT) mechanism, and is often referred to as the VTEC (Variable Valve Timing & Lift Electronic Control) switch. One chunk of pretty good sized iron, again I assume the rocker broke and we will find that once the other valve cover is off. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic for $114. Not made of money but can make it happen either way. The rocker arm actuator is an oil pressure switch which controls the flow of oil to critical upper engine cylinder head components. So glad someone posted this. I'll be changing it tonight and swapping out the vtec solenoid and oil pressure switch from my spare engine. I bet they just got a bad batch of these parts. And if I pull it out I may as well take care of lots of things I'd like to do.
Install the rocker arm oil pressure sensor with a new O-ring. Component Location Index Rear Door.
Oil certainly has some sparkle to it, nothing over the top but its there for sure. The actuator will measure how much oil is flowing through it and report it to the ECM. In vehicles equipped with VTEC systems, the rocker arm control solenoid supplies hydraulic pressure to the variable timing and lift mechanism. This would hurt the oil's viscosity and trigger the P2646. The dealership said he reset the system and that has resolve the P2647 problem. VSA/Hill assist lights went away later that day, only change was clearing the dtcs with an obd2 but the issue still immediately persisted and went away when I drove it a few hours later. Doubtful, but they are sure to tell you that it was caused from the "Non" Honda filter. The back of the rear seat folds down, giving you direct access to the trunk. The onboard computer (ECM) receives information from the oil pressure switch if the system is working correctly. Some months ago my vehicle went into limp mode throwing code P2652, by the time I towed it to the shop, it went away.
Make sure that it doesn't look milky. The VTEC system controls the variable valve timing in your Honda. Many mechanics may misidentify the location of the rocker arm actuator at fault. One of the first steps a technician will take when diagnosing a P2646 code is to verify that the engine maintains the correct oil level and has the proper viscosity. I cleared the code, and it came back immediately when I restarted the car. I think I have a bad switch or maybe it is due to the oil filter as the dealer suggested.
I do typically prefer to pre fill the filter and on Honda's it is usually easy as they install with the opening up or primarily in the up position. '07 model J35A6, J35A7 engines: Remove any old liquid gasket from the switch and switch mounting hole. Pulling into the parking lot it again gets very loud again and I shut it off. Shows up as an intermediate problem.
They changed my oil and filter and no issues since then. Did they at least change or even check the oil? You must login to post a review. Once it is full close the port up, wipe up any spilt oil and You will be finished.
Current oil level is full and has about 500 miles usage. Using a funnel fill the oil pan to full, but make sure to not overfill. Trace the wiring back and see if it is damaged anywhere. It is important to use a proper diagram for your specific vehicle to distinguish the two actuators. Install the parts in the reverse order of removal with a new O-ring (A), See also: Winter Tires. The engine depends on oil to produce a frictionless environment for the engine components moving at extremely rapid speeds.
