Hi everyone, I have a 65 plate Qashqai 1.6 dCi Tekna and in general I'm very happy with it. But this week my engine management light came on so I had a diagnosis run and it came back with the following problem. P1135 O2 Downstream process sensors. With more than one sensor on the exhaust system can anyone tell me which sensor it is or help me with this problem>
Many thanks in advance for your help.

Had a look for that engine/exhaust configuration and not found. Anyway, downstream is the sensor after the cat converter. So should see a couple of wires heading that way. Prepare the blow lamp?
Function of second O2 sensor is to ensure the cat converter is working correctly.

Ditto spec car ditto problem last year dealer replaced sensor under warranty. The fact they had them in stock suggests a regular “service” item
