Hi all,
I have been chasing an issue with the bank two circuit A open circuit error code. It was showing a P0345. That however is now gone and I am getting this new P0020 code. Car idles rough and lacks low end power. It starts and drives pretty normal otherwise. Back story. I recently did some repairs. Swapped out AC compressor, and replaced waterpump and valve cover gasket on the side of the engine in question. I am hoping someone has a confirmed fix and some experience with this issue. I have replaced intake camshaft sensor and plug, crankshaft sensor and VVT sensor plug as some bare wire was showing. None of these items fixed or changed my issue. After I clear code, the enging light is not present, no matter how long I drive the car, BUT as soon as I shut it off and restart, the engine light is forever present. Any thought would be appreciated.
