p0136 HO2S2(B1) nissan patrol diesel

Question

please advise me on this fault code P0136 HO2S2(B1), this fault code coming on Nissan patrol diesel but there are no more any oxygen sensor mounted in the exhaust manifold.

Answer 1

Hi there

This is the rear sensor in the exhaust pipe, not the one in the exhaust manifold. Check the exhaust pipe and I suspect you will find one AFTER the converter. This would be the sensor to replace.
