    Problems & Issues
    So I bought this CR-V with 150k miles on it a few years ago, has 176k on it now. Ever since around the start of this year the gas mileage has gone completely to hell. Basically there is a multitude of problems showing up. 1. I've noticed my coolant has been going down super fast lately...

    Hi, I hope this is the correct area to post this? I recently had the P2646 code on my 2004 Honda CRV. I replaced the entire spool valve assembly - part number 15810-RAA-A03 Vtec Solenoid Spool Valve & Oil pressure Sensor. I then changed the oil and filter with the recommended oil weight...

    Hi I’m new here. I’ve done a tremendous amount of research online about this error code and I’m aware it’s a general code possibly relating to the VVT, VTEC or Rocker Arm Oil Pressure Switch. The CRV is new to us, less than a month has 108,000 miles on it. The car fax record shows incredible...

    Oil level correct, new vtec assembly installed with new filter screen. Still the same p2646 code popping up. Read a bunch of similar post, with most cases having low oil/screen issues. I however have not had any luck with any of these solutions. I have bought the oil sending unit switch and...

  12. Code P2646 and VSA related?

    Maintenance and Service
    I am getting code P2646. I can handle that, I think. The weird thing is that my VSA light is coming on at the same time. I haven't seen anyone on the interweb mention that their VSA system gave them problems at the same time. The lights came (and come) on at the EXACT same time, even after...
