Mpu9150 not working

Hi, I am trying to establish communication with mpu9150 ic. I tried to communicate with the ic using 0x68 and 0x69 with appropriate voltage to the AD0 pin. But I didn't get an acknowledgement from the device. All I get for sensor data is just zeroes.

However I found that cout it pin is at 0v. I guess that the 2.2nf capacitor is causing the issue. But still shouldn't I receive acknowledgement when I try to establish connection ? Doesn't that cpout pin corresponds to the working of the acc and gyro sensor and not related to the interface?

Any info regarding this would be helpful.

Thanks
