2009 Toyota Sienna ignition malfunction. P0018, P0019 and P0300 diagnostic codes.
Code reader shows bank2 sensors 1 & 2 correlation with crank sensor issue. Bank1 has no
issue. Code P0300 also shows random misfire. Does crankshaft sensor affect Bank1 &
Bank2 independently? Will replacing crank sensor correct issue?
After having A Toyota tech come to my house to check it out, it is still not repaired. Toyota is aware of the problem. It occurs frequently after 100,000 miles on the 2GR FE engine. Toyota refuses to offer any assistance in warranty coverage and no recall is on the horizon. Toyota has a service bulletin for Toyota technicians, which involves throwing parts at it at the customer's expense. Parts include sensors and camshaft solenoids. If that does not work, the engine must be removed from the Sienna and the camshaft drive gears,(which have hydraulic advance mechanism built into them) must be replaced. The job has a 15 hour time flat rate. Toyota will not install a customer's own parts. You must buy the parts from Toyota. The total job which also can include timing chain, water pump, hoses, etc. will run around $6000.00. I am still trying to find another shop to perform the work, using parts I can purchase from aftermarket sellers. I have become very disenchanted at Toyota's callous attitude in dealing with a known manufacturer defect. I will never again buy or recommend Toyota vehicles. I
I have been fighting a problem that is getting increasingly worse. The 2006 Sienna will always crank, but won't start when cold, after about a dozen tries it seems to start most of the time. When it is warm it starts fine. I replaced the fuel pump myself, but that did not fix the problem. The dealer cleaned the Mass Air flow Sensor for another problem, then replaced the crank shaft sensor for this problem after telling me it was the fuel pump was a fault (they later decided to not replace my four month old fuel pump). One time we got a P0018 error (Cam & Crank shaft position sensor mis-match), the rest of times, no errors. I am going to replace the Cam shaft sensor next, but there is no guarantee that will work.
