P0021 Diagnostic Trouble Code On 2003 Toyota Sienna Van by morgannanim: 12:13am On Jun 09, 2020
My car was running fine except that it usually throws P0301 and P0306. I changed the spark plugs(with Iridium Type) and injector nozzles
the problem persisted. The misfire codes occurs especially when climbing a steep ground. So my Mech advised than I should grind the valve seals, Top gasket, oil seals etc. After the job was done I started experiencing these codes: P0016,P0018, and P0020. To solve this we changed the Camshaft variable selenoid. Then came the P0021. Now the car performance is even worse than at the start. Can anyone out there help me out
