I don't know if that is true but is possible. Only the people at Bosch know the answer for sure. Honestly I've never heard of anyone having a failed cam position sensor. However many, many of our cars have had failed crank position sensors. I also think that people only replace the cam sensor because they get it confused with the crank sensor so therefore they just order both. I think I bought my crank position sensor on Amazon and it was about $25.00 - $30.00 US.
