Question on error code PS2647
Hello y’all! A little about my fit for starters, it’s an 08 GD3 with 48,000 miles on it (i know). I recently got a CEL with the “'A' Rocker Arm Actuator System Stuck On Bank 1”. I tried to remove and replace the VVT switch on the top of the solenoid it self but was unable to remove it. i ended up purchasing an aftermarket replacement VVT solenoid from autozone for about $110. The check engine light came off and they allowed me to go above 3800 RPM again. today a few days later after the installation, the CEL came on again. I figured it may be the connectors so I used connector cleaner to clean them out and redid some of the heat shrink and put some electrical tape around the bases. I fully disconnected my battery to cycle the ECU and drew out the remainder of the power. Reconnected everything and started the car CEL was off, but after giving it some gas, it came back on. i’m not quite sure what to do. I could always buy the OEM part from Honda but it’s priced at $350. any suggestions?
It wasn't mentioned so I have to ask... Did you verify that the engine oil level is within the "safe" zone of the dipstick?
The VTEC system is oil pressure based so low oil level yields low oil pressure and the rocker arm actuator can stick open or close depending on system operation.
If good, I'd check the oil filter screen for the VTEC spool valve assembly. Considering that the vehicle is around 18 years of age, there is a chance that there is a blockage/restriction hindering flow to the spool valve or one of the internal seals failed and isn't allowing adequate pressure to build within the spool valve if the seals are original.
If that checks out, then I would check continuity across the solenoid switch to verify it is good then verify that power is being sent to the switch via pin 1 which should be to a blue wire with a black tracer. If voltage is present and the switch is good, then you're having to chase down either an electrical issue such as an open in the wire or a PCM fault.
Best of luck... Usually the most common remedies are either low engine oil level (which is shockingly common for folks that aren't car maintenance savvy) or the pressure switch failing (which Honda released a service bulletin on 10 or so years ago for this very issue, TSB 13-021).
