2019年1月27日 · The fact that P1663 won't clear suggests that there's an electrical problem somewhere in the harness. "Easiest" is relative. You'll need a wiring diagram to find which color wires are involved and where connectors are located -- and a volt-ohm meter with a continuity option that tells you whether electricity can flow from the connector at the ...

2018年11月3日 · Since then, the car seems to consistently register P1663 along with P1354 (Bank 2 VVT malfunction) and P1155 (MAF sensor heater circuit). I'd previously replaced the Bank 2 VVT solenoid (in Apr, ~216K) due to a P1354 coupled with rough running (misfires, w/ 30X/Y/Z) when the car warmed up and just because I had the part, went ahead and replaced ...
