Hey guys, hoping someone out there can help point me in the right direction for a recurring issue I'm having with an N/A 05' Elise with 26K miles on it.
**back story**
About a month ago my car threw code P0012. Had two shops check it out and ultimately I was told the VVL sprocket/actuator/gizmo went bye bye so it was replaced. Prior to that the car was in "limp" mode and started/ran fine, just no second cam.
**end back story**
After getting the car back I could once again use the 2nd cam, car ran strong for a few days, now it's continuously throwing P2647.
The Lotus Service notes PDF I scrounged up online calls the error:
A Rocker Arm Actuator System Stuck On
So one of the first things I did was changing my air filter and cleaning my MAF sensor and throttle body. I checked for any loose or ill-fitting wires and came up dry. I checked the fuses in the engine bay, no issues there. I've searched here and Google and found a few threads from people with this error but none of their fixes have worked for me thus far.
The very last thing *we* did, and I say we because Kimgt on here helped me a ton with this, is to replace the VVL Pressure sensor as seen here:
Toyota/Lotus OEM Sensor-VVL Pressure 2ZZ (LOTUS A120E6373S)Used - TOY-83530-20030-U van Toyota OEM
We found one at AutoZone and swapped it in, drove for a bit, etc and now the code is back yet again. Very last thing I've done is to clean the wiring connector for this particular sensor in the off chance I might get lucky.
If anyone knows of something else that I should be checking, please chime in.
Here are the threads and sites I've referenced thus far:
