Do I have to get the P2A00 upstream O2 sensor replaced too?

Question

I have an 06 Nissan Altima 2.5 S. I have the engine codes of P0725, P0335, and P2A00. After some research, I have found that the Crankshaft Positioning Sensor is a common malfunction on this car. If I have this replaced, will it clear both P0725 AND P2A00 issue out?? Do I have to get the P2A00 upstream O2 sensor replaced too?? Or is this because of the Crankshaft Positioning Sensor too??

Answer 1

HI there

The crank position sensor will usually solve the P0725 and the P0335 odes. You will have to replace the O2 sensor to resolve the P2A00 code.This isn't caused by the crank sensor.
