P0017 - Crankshaft Position - Camshaft Position Correlation Bank 1 Sensor B

I recently had this Camry brought to me with a check engine light concern. The vehicle was purchased at auction with unknown history. Fault #P0017 Camshaft Position Correlation (Bank 1 Sensor B) is the only fault stored. The vehicle drives normally and when looking under hood i noticed both cam control solenoids appear recently replaced... Verified solenoids function properly and control circuit was OK. So i scoped the both cams and crank diag​.​net/file/f44fw89mp… ​to compare the pattern with a known good. diag​.​net/file/f6avx8u2n… ​ ​I notice the exhaust cam is out of line - intake to crank looking fine. We recommended replacing the Exhaust Cam Sprocket not knowing what exactly we would find with tear down. After removing the exhaust sprocket and not seeing anything obvious we started checking some numbers we found this engine had a California Emissions Sprocket on a Federal Emission Vehicle (guessing this engine had been replaced with a used unit at some point) Keep your eye out for this issue!

Federal Exhaust sprocket # 130700V013

California Sprocket # 130700V020

I had this exact issue a few weeks ago. The exhaust Sprockets are also different across year models. the customer wanted to change the ecm instead of replacing the timing components. I researched It. It won’t work. The pins are different between the ECMs. It is essential if a used engine is installed that it comes from the correct year model and emission certification. thanks for sharing.

If we could just get all of the information together on things like this. The wrecking yard probably looked it up and said it will fit. Their info probably said it would fit...........Good find.

Great catch. I would not have thought there would be a difference like that. I'd love to know the difference between California and Federal sprockets. I mean, the have to have the same number of teeth and diameter, and the ECM would just run the timing differently.
