NEW LAMBDA OXYGEN O2 SENSOR FOR NISSAN QASHQAI MK2 J11 1.2 DIG-T 2013 226A47260R

Restore correct air-fuel mixture, fuel economy and emissions performance on your Nissan Qashqai MK2 J11 with this direct-replacement oxygen sensor — also known as the oxygen probe, exhaust gas sensor or pre-cat sensor. Built to OEM specification and matching part numbers 226A47260R, 22690-00Q1D, A4155420100, 8200632270 and 8201035691. Also fits equivalent Dacia, Mercedes-Benz and Renault models.

Common signs of failure

A failing lambda or oxygen sensor will turn on the check engine light and commonly log fault codes in the P0130–P0167 range (sensor circuit and heater faults). Drivers typically notice a sudden drop in fuel economy, rough or fluctuating idle, hesitation under load, a sulphur or rotten-egg smell from the exhaust, and in many cases an MOT emissions failure. On modern diesels and direct-injection petrols, a stuck or slow-responding sensor can also push the engine into limp mode.

Fitment notes

Plug-and-play installation with the correct factory connector — no diagnostic coding required. Most engines run a pre-cat (upstream) and a post-cat (downstream) sensor; cross-check your existing part number and the position on the exhaust to make sure you're ordering the right one. Apply a smear of anti-seize compound on the threads before fitting and torque to manufacturer spec.

Frequently asked questions

How do I know if my lambda sensor is faulty?

An OBD2 scan showing P0130-series codes plus poor fuel economy is the clearest sign. Live data showing the sensor stuck at a flat voltage (instead of oscillating between roughly 0.1V and 0.9V) confirms a faulty sensor.

Pre-cat or post-cat — which one do I need?

Pre-cat sensors (upstream of the catalytic converter) control the fuel mixture. Post-cat sensors (downstream) monitor catalyst efficiency. Match the OEM number on your old sensor to the numbers listed above to be sure.

Will a new sensor fix my fuel economy?

If the original sensor is biased lean or rich, a correct replacement typically restores MPG within a tank or two of fuel. Drive at least 20-30 miles after fitting to allow the ECU to re-learn.
